Safety Chucks and Special Solutions

The safety chucks presented here, are easy and simple to use and have the following advantages:

  • The basic version already comes as a wearing part exchange bearing.
  • The open mechanism slides and offers a lower crushing hazard, compared to flap bearing.
  • An optimal torque transmission

They are offered as flange or pedestal bearings and can be delivered with or without square gudgeon.

After the material web is clamped by the pneumatic shaft with leaves, it is ready to begin the winding process.

The web can be clamped easily, using a special designed leaf (picture 4)
