ALPHATRIM P winders have pneumatic powered traverse movement with a simple web path for quick threading. The traverse rate can be adjusted by the operator and automatically switches off when the line stops.

Each trim winder is driven by its own variable speed motor running under closed loop tension control from a precision pneumatic dancer.

Alternatively, where space is at a premium, the winder motor can be operated under direct torque control. Full sized rolls can be unloaded quickly and the winder restarted. ALPHATRIM winders are fitted with a remote air inflation system on winding shafts for paper cores or a quick release mechanism on coreless shafts.

Examples shown:

  • Standard pneumatic traversing trim winder with pnematic coreless chuck.
  • Pneumatic traversing trim winder with pull roll constant tension drive section for nonstop manufacture of flooring products.
