Film Edge Cutter Film Roll Trimmer

EC-TRON ROLL EDGE CUTTER for cling film rolls Trimming

Automatic Film Roll Edge Trimmer converts PVC and PE cling film rolls from an extrusion line or printing press into a higher quality product. Designed and built in Canada, the TRONOPLAST Roll Edge Trimmer will automatically cut the edges of cling film roll on paper cores, resulting in uniform finished rolls of film with clean, burr-free, square edges. Finished film rolls are centered on their cores, easy to unwind. All mechanical movement is controlled by the PLC.
The TRONOPLAST Roll Edge Trimmer is easy to use. There are two symmetrical cutting knives with a motor and gearbox driving one core chuck, the opposite chuck is free turning. The roll turns against the fixed knife blades which simultaneously cut through the film roll toward the paper core. The offcuts fall into discharge chutes and the finished roll is removed by the operator. All parameters are set on the HMI including final film width; core outer diameter and roll outer diameter.
Manual positioning of the knives relative to the print (cycle interruption). Knife positions are indicated by laser pointers. The PLC codes and software licenses are free.
