ALPHATRIM TWM trim winders are designed to provide compact, high speed, efficient removal of trim from converting lines without the noise, dust and high cost of installation associated with many vacuum systems.

The ALPHATRIM TWM is a stand-alone unit which does not need any integration with the host slitter. Each trim winder is driven by its own variable speed motor running under closed loop tension control from a precision pneumatic dancer, which automatically tracks the speed of the host slitter.

Rewinding is either on a cardboard core or coreless to provide even easier recycling opportunities.

With speeds up to 600mpm and operator adjustable tension and oscillation control the ALPHATRIM TWM provides a very simple and efficient trim winding solution.
