GravoSlit Drum is especially designed for handling all types of multilayer laminates used in flexible packaging like aluminum foils, polyester films, paper based laminates. These machines work on surface and center winding principle, therefore both rewind shafts are driven by dedicated AC motors and dedicated AC frequency drives. As the rewind reel is wound on center drum, soft and delicate materials can be handled carefully.
Unwinder and Rewinders are isolated by a nip with a dedicated drive through an AC frequency drive. All these drives are controlled in a closed loop by SIEMENS PLC. Touch screen panel is provided to set job parameters.
