2026-08-02
In rubber and plastic extrusion lines, the stability of the traction equipment directly impacts product yield. Dual‑belt traction units, with their flexible clamping and synchronized conveying capabilities, are well suited for producing soft profiles such as silicone and butyl rubber, addressing issues like slippage, indentation, and profile distortion. When integrated with extrusion and shaping equipment, they help enhance quality and boost efficiency across the entire production line.
The haul‑off unit is a critical component of rubber and plastic extrusion lines. The dual‑belt haul‑off, with its flexible clamping design, addresses common challenges in soft‑material processing—such as compression damage, web misalignment, and slippage—while ensuring consistent product dimensions and helping manufacturers enhance line quality and efficiency.
Many rubber and plastic manufacturers, when purchasing production lines, place primary emphasis on the extruder while overlooking the importance of the traction equipment. The traction unit handles the shaping and winding processes, and its operational condition directly affects the quality of finished products such as sealing strips and adhesive tapes.
Traditional traction devices each have their own limitations, whereas the 90 dual‑belt traction machine employs flexible upper and lower polyurethane belts for uniform force application. When processing soft materials such as silicone, butyl rubber, and foamed rubber, it avoids indentation and flattening defects. The pneumatic pressure is continuously adjustable, making it compatible with a wide range of adhesive strips and tubing specifications.
The equipment features dual-belt synchronous drive, effectively preventing profile twisting and deviation; it supports servo and variable-frequency configurations, enabling speed control in coordination with the extruder to precisely regulate the stretching ratio. This ensures stable, long-term continuous production speeds, reduces dimensional tolerances, and significantly lowers the defect rate.
The equipment features a compact design that facilitates production line layout, with easy belt removal and installation, low ongoing maintenance costs, and an optional photoelectric web‑guidance system, making it suitable for continuous vulcanization and long‑line production of butyl tape.
Line upgrades represent a comprehensive system optimization; only through the coordinated operation of extrusion, shaping, and traction equipment can production capacity be maximized. Appropriate twin‑belt traction systems help minimize production losses, ensuring stable operations for your enterprise.
