cylinder roll

The cylinder roll is the core processing component of roll carding machines widely used in nonwoven and textile manufacturing. Assembled with multiple rotating roll units covered in dense comb teeth, it grips scattered fibers and arranges them into ordered, aligned structures, while regulating fiber length and fineness to prevent fiber breakage under stretching force.

Its core function lies in thorough secondary carding: it processes fiber bundles peeled off by the licker-in, splitting tangled clusters into independent single fibers. Meanwhile, the cylinder eliminates short lint and foreign impurities, straightens crumpled fibers and realizes even fiber blending before delivering clean, uniform fiber webs to the matched doffer roll.

Manufactured from solid steel, our cylinder rolls provide standard diameters of φ1230mm and φ1500mm, with full custom sizing available. The rotational runout is strictly controlled between 10μm and 20μm to maintain stable vibration-free rotation. As the heart of the carding system, this steel cylinder roll guarantees consistent fiber quality, reduces waste and boosts the stability of continuous nonwoven production lines.

Parameters

The cylinder roll is universally recognized as the absolute core component of industrial roll carding machines, serving as the key functional unit that determines the overall carding quality in modern nonwoven fabric production and traditional textile processing lines. It undertakes the most critical fiber opening, combing, separation and web refining procedures throughout the entire carding workflow, directly influencing fiber neatness, web uniformity, material purity and the final physical performance of finished nonwoven products. A complete cylinder assembly consists of multiple high-precision synchronously rotating roll units, whose outer working surfaces are densely arranged with high-hardness professional comb teeth. These specially designed comb structures firmly capture loose, disordered and intertwined raw fibers delivered by the licker-in roll, systematically straighten chaotic fiber arrangements, and standardize fiber orientation, angle and spatial positioning during high-speed circulation. In addition to regularizing fiber posture, the cylinder roll precisely controls the effective length and fineness of processed fibers, effectively avoiding excessive stretching damage, fiber breakage and irregular fragment separation under continuous mechanical tension. This fundamental protection mechanism ensures stable fiber integrity and lays a solid foundation for consistent, high-quality nonwoven web forming during long-term mass production.

 

The functional value of the cylinder roll is irreplaceable, as it completes deep fiber refining that preliminary licker-in carding cannot achieve. The licker-in only performs rough primary opening of raw fiber materials and inevitably leaves large quantities of tightly tangled fiber bundles and unseparated fiber clusters. In contrast, the cylinder roll executes full-scale, meticulous secondary carding and deep untangling to thoroughly divide aggregated fiber bundles into individual, independent single fibers. During this intensive combing cycle, harmful short lint, fine dust, tiny impurities and inferior broken fiber fragments mixed in raw materials are fully screened, stripped and removed from the fiber layer, greatly enhancing the cleanliness and purity of the final fiber web. Meanwhile, the continuous reciprocating combing action straightens curled, folded and twisted fibers, promotes sufficient cross-layer fiber mixing, and realizes uniform density distribution across the entire working width. After completing standardized refining and homogenization, the clean, neat and evenly blended fiber layers are steadily transferred to the doffer roll for subsequent fiber stripping, continuous web forming and stable material output.

 

Our cylinder rolls are integrally manufactured from high-strength premium steel materials, featuring outstanding structural rigidity, excellent surface wear resistance and strong anti-deformation performance. The robust steel body fully adapts to long-duration, high-load and high-speed continuous industrial operation, effectively resisting mechanical fatigue, surface abrasion and structural distortion after thousands of working hours. The product series provides two widely adopted standard dimensional specifications: φ1230mm and φ1500mm, compatible with most mainstream standard carding machine models for nonwoven and textile production. Meanwhile, we support fully customized diameter, working length and structural parameters to meet personalized processing requirements of different fiber materials and production line configurations.

 

Each finished cylinder roll undergoes precise finishing machining and strict dynamic calibration. The rotational runout is rigorously controlled within 10μm to 20μm, ensuring ultra-stable, vibration-free high-speed rotation. The ultra-tight mechanical tolerance maintains consistent carding gaps across the full roll surface, eliminating uneven combing, local fiber sparseness, dense fiber accumulation and other common defects, and effectively stabilizing the thickness uniformity and surface flatness of nonwoven fiber webs.

 

Cooperating precisely with licker-in and doffer rolls, this high-precision steel cylinder roll builds a complete, efficient and stable fiber carding circulation system. It significantly resolves typical production pain points including tangled fibers, high impurity content, poor fiber mixing uniformity and unstable web forming quality. Ideal for high-standard nonwoven and textile manufacturing scenarios requiring low defect rates and high consistency, the cylinder roll delivers durable and reliable long-term carding performance, greatly improves overall production efficiency, and effectively reduces raw material waste and daily equipment maintenance costs for manufacturers.

PRS Cooling Rolls Specialized Cooling Equipment for BOPP, BOPET and BOPA Tra

PRS Cooling Rolls Specialized Cooling Equipment for BOPP, BOPET and BOPA Tra
1 Introduction For enterprises equipped with biaxially oriented film production lines, stable and uniform cooling treatment after transverse stretching (TDO) is a key factor to guarantee film dimensional stability, surface flatness and consistent mechanical indexes. PRS cooling roll is the core cooling component installed in the traction section of the production line. In the standard film stretching process, three types of PRS cooling rolls will be used in matching sequence. This paper systematically expounds three surface treatment schemes for PRS cooling rolls, analyzes the hidden danger of ozone corrosion to conventional rolls, lists complete standardized technical parameters, and shares mass application cases in global film manufacturing workshops. 2 Three Types of PRS Cooling rolls Matching Different Process Segments Three differentiated surface treatment processes are developed to adapt to different working environments of each node on the film stretching line. The maximum applicable film width of all three roll types reaches 10.6 meters, and the supporting operating speed can be adjusted according to production demands. 2.1 Hard Chrome Plated PRS Cooling roll The roll surface adopts thick hard chrome electroplating process. The product features outstanding wear resistance and fast heat exchange efficiency. It is specially configured for the working section immediately after TDO transverse stretching equipment, with a maximum matching line speed of 600 m/min. 2.2 Anti-Stick Coated PRS Cooling roll The surface is covered with special non-adhesive functional coating, which can effectively avoid the adhesion phenomenon of hot soft film on the roll surface and eliminate surface sticking defects of finished products. It is suitable for the middle traction area after primary cooling, and the maximum applicable line speed is 650 m/min. 2.3 Ozone Anti-Corrosion PRS Cooling roll The whole roll body is made of anti-corrosion stainless steel substrate, which can resist oxidative damage caused by ozone generated during corona discharge. It is installed behind the corona treatment equipment, with a maximum operating speed of 650 m/min. All three series of PRS cooling rolls can be perfectly matched with the production processes of BOPP, BOPET, BOPA film and adhesive tape. 3 Ozone Corrosion Risk Analysis of Ordinary Cooling rolls In the corona surface modification procedure, high-voltage discharge will produce a large amount of ozone with strong oxidizing property. If ozone permeates the surface coating of ordinary chrome cooling rolls, long-term operation will cause chemical corrosion, resulting in bubbling, blistering and complete peeling of the coating. It is necessary for production management personnel to pay attention that simple surface recoating cannot solve the permanent structural damage caused by ozone corrosion. Once such failure occurs, the whole cooling roll must be replaced. Partial surface repair will lead to repeated coating shedding and unplanned production shutdown losses. 4 Complete Standard Technical Parameters of PRS Cooling roll All PRS cooling rolls adopt double-shell circulating water cooling structure, and the water inlet and outlet are arranged on the same end of the roll body: 1.Raw material configuration: The inner and outer barrels are made of Q345B structural steel, and the outer barrel is assembled by precision interference fit process. 2.Internal flow channel: Independent water flow pipeline can be customized according to the layout of each customer’s production line. 3.End structural parts: The driving side is equipped with high-strength low-carbon alloy steel forged flange and solid roll shaft; the operation side adopts alloy forged flange and shaft head, fixed by interference fit and full welding. 4.Precision tolerance standards: Out-of-roundness ≤0.1 mm, cylindricity ≤0.1 mm. 5.Dynamic balance grade: G2.5, which can adapt to the maximum production line speed of 630 m/min. 6.Optional surface treatment processes: Hard chrome plating, anti-stick functional coating, ozone-resistant anti-corrosion coating. 5 Global Industrial Application Cases The company has provided customized PRS cooling roll supporting schemes for more than 100 complete BOPP and BOPET production lines covering more than 10 countries and regions around the world, and has established long-term stable cooperative relations with many well-known film manufacturing groups. After replacing the old cooling equipment with our PRS cooling rolls, the film stretching process of all cooperative customers is optimized, and the overall production efficiency is increased by 5% to 10%. 6 Customized Equipment Matching Service For manufacturers who need to build new biaxial film production lines or carry out old roll replacement transformation, the professional engineering team can provide one-to-one parameter matching, personalized structural design and full-cycle technical support services.

Principle, Structure and Performance Comparison of Electromagnetic Induction Heating Rolls for Film, Fiber and Composite Processing
1 Overview of Electromagnetic Induction Heating roll Electromagnetic induction heating roll is a self-heating cylindrical core equipment specially used for continuous processing of various industrial substrates such as polymer film, carbon fiber, prepreg and paper. Its core heating principle depends on built-in induction coils. After being energized, alternating electromagnetic fields are generated, and magnetic lines cut the metal roll shell to produce uniform Joule heat inside the roll body. A complete closed-loop temperature control system is equipped to stabilize the roll at the set temperature value, so as to realize stable heat exchange with passing materials. This type of heating roll is widely applied in PVC forming, chemical fiber spinning, composite lamination, material drying and inorganic film stretching production procedures. Compared with traditional thermal oil and water heating rolls, it has prominent advantages in temperature uniformity, environmental protection and operation safety, and has become an indispensable heating component for high-temperature and high-precision material manufacturing. The only limitation is its higher one-time manufacturing cost than oil heating rolls, which restricts its full popularization in the market at this stage. 2 Two Main Structural Classification of Induction Heating roll According to different supporting structures at both ends, induction heating rolls are divided into single-shaft type and double-shaft type to adapt to diversified production process demands. 2.1 Single-shaft Induction Heating roll This product is supported only by one end, and is mostly applied in chemical fiber spinning equipment, as well as drying and stretching production lines of special plastic films. It can be manufactured into integrated structure, split structure or integrated structure matched with driving motor. The standard assembly consists of induction coil group, roll shell, transmission support assembly and temperature detection components. 2.2 Double-shaft Induction Heating roll The double-shaft roll is supported at both ends, equipped with left and right end covers, built-in heating coils and temperature sensing devices. It has a wider range of applicable scenarios, including calendering, surface polishing, material leveling, drying, composite pressing, thermoforming and heat transfer printing. In terms of internal heating layout, there are two technical routes: built-in coil heating and external coil heating. The built-in coil scheme occupies the absolute mainstream position in the industry due to higher heating efficiency, better safety and more accurate temperature control, and more than 99% of industrial products adopt single built-in coil layout. The products developed by our factory adopt this mature design consistent with Japan’s Tokuden brand. 3 Multi-mode Temperature Detection and Signal Transmission System 3.1 Two Types of Temperature Measurement Methods Direct contact temperature measurement K-type thermocouple or PT100 resistance sensors are embedded inside the rollwall to collect real-time temperature data. Among them, K-type thermocouple has lower component cost but needs to be matched with special compensation wires; PT100 sensor has higher data stability with slightly higher procurement cost. Indirect non-contact temperature measurement Infrared temperature measurement: Based on blackbody radiation principle, it is easily interfered by rollsurface roughness, surface dirt, detection distance and angle, resulting in obvious measurement errors. Air temperature measurement: Mainly used for split single-shaft rolls in chemical fiber workshops. Sensors are placed in reserved grooves on the rollend face to detect air temperature changes, and the control system adjusts coil current through PID algorithm to stabilize heating power. 3.3 Three Common Temperature Measuring Positions Air temperature measurement: Widely adopted in chemical fiber stretching production lines rollwall temperature measurement: Drill detection holes of different lengths on the roll barrel for deep temperature collection rollsurface temperature measurement: Realized by infrared or contact thermocouple, with poor stability and rarely used in formal mass production 3.4 Two Signal Transmission Modes Direct signal transmission: The original signals of thermocouple and PT100 are directly transmitted to the PLC temperature controll Converted signal transmission: The original temperature data is converted into standard 4-20mA industrial signals before output, which supports wired and wireless transmission. Wireless transmission is not recommended for rotating rolls due to the need for independent battery power supply. 4 Comprehensive Performance Comparison Between Induction Heating roll and Thermal Oil Heating roll Comparison Dimension Electromagnetic Induction Heating roll Thermal Oil / Electric Heating roll Surface Temperature Uniformity Temperature deviation controlled within ±0.5~1℃ Surface temperature difference exceeds ±4℃ Temperature Control Precision Full digital PLC closed-loop control with high regulation accuracy Long oil pipeline leads to large temperature difference between two ends, difficult to adjust flexibly Maximum Sustainable Temperature Stable operation up to 400℃ Maximum working temperature limited to 240℃ Thermal Energy Utilization Rate Over 95% heat efficiency, power consumption reduced by up to 60% Only about 60% heat utilization rate with serious energy loss Heating Acceleration Speed Rise to 200℃ within 30 minutes It takes 90 minutes to reach 200℃ Remote Control Function Reserved communication interface for remote data viewing and parameter adjustment No built-in remote control module Production Environment Impact Oil-free and pollution-free, clean workshop operation Thermal oil leakage and volatilization risks exist, with potential fire hazards Operational Safety Internal magnetic heating structure, stable and reliable long-term operation Oil pipelines are easy to block, causing unexpected production shutdown Floor Space Requirement No external supporting pipelines, compact overall structure Matching oil temperature machine and complex pipelines occupy large workshop area Average Service Life Stable operation for more than 10 years Average service life only 3 to 5 years Procurement Cost Higher initial investment cost Low upfront purchase price 5 Customized Heating roll Matching Service For manufacturers engaged in plastic film, non-woven fabric, carbon fiber, prepreg, industrial paper and composite material production, our engineering team can design exclusive electromagnetic induction heating roll solutions according to the actual production line speed, target working temperature and installation size limits of customers.

MDO Preheating Rolls Key Heating Components for BOPP and BOPET Biaxial Film Stretching Production Lines
1 Introduction For enterprises equipped with biaxially oriented plastic film production lines, MDO preheating roll is an indispensable core heating component in the longitudinal stretching section. Standardized and stable preheating treatment is the premise to realize uniform longitudinal stretching of film substrates, which can comprehensively optimize the physical properties of finished films and improve the market competitiveness of packaging film products. This paper systematically expounds the core processing value of MDO preheating rolls, three customized surface coating types, complete precision manufacturing standards, and a full series of alternative heating roll products for multiple industries. 2 Core Processing Functions of MDO Preheating rolls The MDO preheating roll is installed at the front end of the longitudinal stretching section of polyfilm production equipment, which evenly heats the raw film before stretching. The moderate thermal softening effect enables the film to complete uniform plastic deformation in the subsequent stretching process, bringing three obvious quality improvements to finished products: First, the tensile strength and rigidity of the film are significantly improved, and the finished film can maintain stable performance in multiple secondary processing links without damage. Second, the optical performance indicators such as transparency and surface gloss of the film are optimized, which greatly improves the appearance quality and added value of packaging film products. Third, the film has better heat sealing performance and ink adsorption capacity, which expands the applicable scenarios of finished products in printing, compound and other post-processing procedures. 3 Three Optional Surface Coating Types for MDO Preheating rolls Different surface coating processes are matched according to the production parameters of BOPP and BOPET film lines to meet differentiated production demands: 1.Teflon coated MDO preheating roll Applicable to BOPP film production lines, the standard specification range is 614mm × 900mm to 614mm × 1500mm, with anti-adhesion and easy-release surface characteristics. 2.Hard chrome plated MDO preheating roll Adopts the same size specification as Teflon coated rolls, suitable for high-load continuous BOPP stretching production, with high wear resistance and long service life. 3.Ceramic coated MDO preheating roll Mainly used for wide-width BOPET film production lines, the mainstream standard specification is Φ350mm × 3300mm, with excellent high temperature and oxidation resistance. 4 Complete Precision Technical Parameters of MDO Preheating rolls All MDO preheating rolls adopt heavy-duty double-shell integral structure and strict precision control to adapt to long-term high-speed continuous operation: The inner and outer barrels, side discs and roll shafts are all made of Q345B steel, and the shaft and disc components are processed by interference assembly and full welding process. Independent welded heat circulation channels are reserved between the inner and outer shells to ensure uniform heat distribution on the whole roll surface. Geometric precision indicators: total runout ≤0.01mm, cylindricity ≤0.01mm; dynamic balance grade reaches G2.5 to eliminate vibration under the maximum operating speed of the production line. 4.1 Parameter Index of Two Main Surface Coatings 1.Hard chrome coating Coating thickness range: 150μm–200μm; surface hardness: HRC 68–70; surface roughness Ra: 0.01μm–0.02μm 2.Teflon coating Optional green or black coating surface; hardness index: HB 220–250 V; coating thickness: 80μm–100μm; standard roughness Ra: 0.1μm–0.4μm; ultra-smooth customized Ra range 0.03μm–0.4μm is available for special process demands. 5 Full Range of Supporting Industrial Heating roll Products In addition to MDO preheating rolls dedicated to biaxial film stretching, the company supplies diversified heating roll products covering multiple processing industries to meet cross-industry equipment matching demands: Induction heating rolls: with low energy consumption and low maintenance frequency, with high safety performance in long-term operation Steam dryer cylinders: customized supporting equipment for various paper production lines Oil-water circulation heating rolls: general heating components for all kinds of flexible web processing equipment Thermal oil calender rolls: special heating equipment for hot forming of nonwoven fabrics 6 Customized Equipment Matching Service As a comprehensive professional heating roll manufacturer, we provide integrated services including customized design, production manufacturing and after-sales technical support for all types of thermal processing rolls.

GODET ROLL

High Precision Induction Heating Godet Rolls for Carbon Fiber, PTFE and High-Performance Synthetic Fiber Manufacturing
Introduction Enterprises engaged in the production of high-performance synthetic fibers including carbon fiber, PTFE yarn, PEEK fiber and PPSF fiber have long been plagued by multiple common production defects in the stretching process, such as frequent fiber fracture, uneven surface heating and fluctuating stretching tension. As the core temperature-controlled transmission component of fiber stretching equipment, high-precision induction heating godet rolls can fundamentally resolve the above production bottlenecks and stabilize the physical performance of finished fiber products. This paper systematically sorts out the structural types, core performance advantages and intelligent linkage control system of induction heating godet rolls, providing reliable equipment reference for fiber factory managers and mechanical engineers. 1 Basic Overview of Induction Heating Godet roll The godet roll is an essential heat transfer component installed on all types of high-performance synthetic fiber stretching production lines. Its internal heating assembly consists of matched electromagnetic induction coils and independent digital control hardware. Two structural specifications are available for different production processes, namely fixed godet roll and rotary godet roll, among which the rotary type has become the mainstream configuration adopted by most large-scale fiber manufacturing workshops. The fixed godet roll does not need supporting power transmission parts, but its overall operation stability cannot meet the requirements of long-time continuous stretching load, which will lead to frequent yarn breakage and substantial raw material waste in mass production. The rotary godet roll is equipped with matched driving components, which can form ultra-smooth conveying paths for fiber yarns. This structural design effectively reduces tension fluctuation during high-speed operation and significantly cuts the reject rate caused by fiber fracture. 2 Core Performance and Functional Advantages 2.1 Wide Adaptable High-Temperature Working Interval The induction heating godet roll can operate stably under a long-term continuous working temperature of 250℃ to 400℃, fully matching the thermal forming technical requirements of various high-temperature resistant special fibers. A 300mm temperature buffer area is reserved at both ends of the roll’s effective working surface to offset heat loss generated by side baffles and bearing components. This structural design ensures uniform temperature distribution in the central working area of the roll and avoids local temperature difference that damages the internal molecular structure of fibers. 2.2 Multi-Protocol Industrial Communication Compatibility The supporting electrical control system is embedded with multiple mainstream industrial communication interfaces, covering ProfiNET, RS-485 and RS-232 protocols. The roll can realize seamless data connection with the central host control system of the workshop, uploading real-time data including roll surface temperature, operating linear speed and equipment fault codes to the unified monitoring platform. 2.3 Synchronous Linkage Control of Rotational Speed and Temperature Two sets of linkage control schemes are reserved to adapt to different production line matching conditions. When matched with the proprietary driving motor supplied by our factory, the supporting control cabinet can display real-time temperature and operating speed data on a single screen to facilitate on-site staff observation. If customers adopt third-party customized driving motors, technicians only need to input the corresponding motor model parameters into the control panel.
