Winding technology

Krüger Industrieautomation GmbH is also productive in winding technology. We produce film winders, film wrapping machines and box filling machines.

 

All of the following standard models can be adapted to your needs.

VKC 500

FEM 500

Description and operating mode

 

The automatic winder type VKW automatically winds small household rolls from a master roll. The following material can be wound: aluminum, paper, PVC, polyethylene and similar.

The essential item of the machine is a revolving system with four positions. Here empty paper cores are picked up from the magazine in cycles, the foil is wound and the finished roll is removed by a gripper. The roll is deposited onto a conveyor. On request, a labelling device for allround labels can be attached.

 

The PLC- control regulates the fully automatic operation. It comprises a function monitor indicating errors as well as their position. The winding speed can be varied infinitely. The winding length is measured electronically. The operation of the machine is controlled via touch panel.

 

Available equipment:

  • Curling device for cling film rolls
  • hot melt system for film/foil start on core
  • embossing system for aluminum foil

Description and operating mode

 

The automatic rewinder type SKW 450 automatically winds small household rolls from a masterroll. The following material can be wound: aluminium, paper, PVC, polyethylene and similar. The essential item of the machine is a revolving system with six positions. Here empty paper cores are removed from the magazine in cylces, the foil is wound and the finished roll is deposited onto a conveyor. The foil is put onto the core either by vacuum or by glue.

 

The PLC-control regulates the fully automatic operation. It comprises a function monitor indicating troubles as well as their position. The winding speed is infinitely variable. The winding length is measured electronically. The operations of the machine can be adjusted over a touch panel.

 

Available equipment: Aluminum foil rolls can be closed by hotmelt dot or lable. For an easy start on clingfilm rolls, you can create a curl with a curling device. For aluminum foil there are different types of embossing systems available.

Description and operating mode

 

The automatic rewinder VKC 500 converts master rolls of film and aluminum foil to small rolls for catering use.

 

The master rolls of up to 1000mm diameter are lifted by a hydraulic unwind station. The four-spindle-turret is equipped with four servo motors. A high-speed knife cuts the film and foil. Rewinding is effected with a constant speed of up to 750 m/min or a maximum speed of 1.000m/min with interval. Made in Germany.
