bi-oriented film rolls

Engineered for high-speed primary winding and heavy-duty rewinding sections, our High-Precision Contact Roll (Winding Pressure Roller) is the industry standard for securing flawless roll structures. Positioned at the critical final convergence point of film lines, this contact roller applies micro-calibrated, synchronized linear pressure against the growing film log to forcefully evacuate entrained boundary air. Available with specialized lightweight engineered cores and wrapped in advanced anti-static elastomers (such as premium polyurethane, conductive NBR, or super-smooth micro-matte hard chrome), it effectively eliminates defects like telescoping, starring, and tension wrinkles. Backed by strict ISO G1.0 dynamic balancing and micron-level straightness tolerances (≤0.01mm), our Contact Roll guarantees smooth, scratch-free web scaling and uniform winding hardness profiles for wide-format packaging and premium optical functional films.

Engineered for ultra-high-speed secondary slitting and rewinding sections, our High-Precision Slitter Contact Roll (Grooved Winding Roller) is the definitive solution for achieving flawless roll profiles and edge alignment. Operating at the final stage of film converting, this contact roller applies synchronized, uniform linear pressure against the winding log to effectively expel entrained air, eliminate bagginess, and prevent telescoping. Wrapped in advanced anti-static elastomers (such as premium polyurethane or customized synthetic rubber) and precision-engineered with spiral or longitudinal venting grooves, it protects delicate film surfaces from micro-scratches and static accumulation at speeds up to 1000 m/min. Backed by rigorous ISO G1.0 dynamic balancing and exceptional structural core concentricity, our Slitter Contact Roll guarantees optimum winding hardness and pristine roll aesthetics for your premium flexible packaging and functional film products.

Engineered to act as the ultra-responsive "dynamic buffer" for high-speed web handling lines, our High-Precision Floating Roll (Dancer Roller) delivers unmatched sensitivity for real-time tension transient absorption. Operating across critical web accumulation and acceleration zones in film orientation, coating, and converting lines, this roller features an ultra-low inertia architecture—utilizing advanced thin-walled aviation aluminum alloys or high-rigidity carbon fiber. It eliminates mechanical lag and breakaway friction, allowing the roller to pivot or translate instantly to absorb sudden tension shocks from cutting or turret roll-changes. Featuring absolute geometric straightness (≤0.01mm) and meticulous ISO G1.0 dynamic balancing, our Floating Roll prevents signal chatter and film flutter, ensuring an exceptionally stable, scratch-free web path for delicate packaging and functional optical films.

Engineered to sustain immense radial compression forces and massive winding torques, our Heavy-Duty Winding Core (Winding Mandrel / Steel Core Shaft) is the industry benchmark for high-speed primary winding and precision slitting operations. Functioning as the structural spine at the final winding station of wide-format film extrusion and specialty paper lines, this mandrel is fabricated from high-tensile forged alloy steel or stress-relieved structural tubes. It guarantees maximum deflection resistance under continuous log weight accumulation up to dozens of tons. Featuring sub-micron geometric concentricity and rigorous ISO G1.0 high-speed dynamic balancing, our Winding Core completely eliminates mechanical vibration and web flutter at line speeds up to 1200m/min. Tailored with optimized surface treatments or mechanical expansion locks, it ensures zero slip and scratch-free roll initialization for premium packaging, optical films, and non-woven substrates.
