Trim Winders Accessories
Ashe trim winders are designed specifically for the high speed collection of narrow width trim off-cuts that are removed from foils and films during the converting process.
Operation
The spindle drive is controlled by a digital inverter drive, capable of both driving and stopping the motor. Material is fed to the spindle via a spring-loaded dancer for tension control, equipped with a position feedback sensor. Together with the PID controls on the trim winder control board, this provides a speed reference for the spindle drive. The system operates to maintain the dancer in a fixed position, thus providing static rewinding tension.
The tension is set by the position of the dancer. When the dancer is close to the infeed roller, the trim tension is high. When it’s furthest away from the infeed roll, the tension is low. Dancer position is set by the internal set tension potentiometer. The dancer is mounted on a cross travel mechanism, and acts as a layering guide to the trim.
The cross travel is controlled by a lead screw and nut with automatic end reversing, so that the lead screw always rotates in one direction. The traverse motor is controlled by a digital inverter drive operating directly from the AC supply. A setpoint isolator on the control board links the winding motor speed reference with the traverse motor so that they operate in unison.
The winder can either be stopped and started from the remote control push buttons or linked directly to the main feed machine. A trim break detector on the control operates three seconds after start up to stop the winder if the dancer hasn't been pulled off its end stop position.
