Device for spreading out plastics foil covers to cover stacks - has side fold clamps between expanding plates and cutter to keep outer side fold edges constantly clamped without further measures.

摘要

The four side fold clamps (8) which detachably clamp the outer edges of a pre-spread side fold are arranged between the expanding plates and the cutter (10'). Between the foil tube supply and the expanding plates (7) is a tube retraction device (6) which draws back the side fold tube with the side fold edges remaining engaged in the opened clamps after separation of the hood until the lower edge of the side folds is located in the clamping area of the open clamps without protruding down beyond same. A holder (15) between the retractor and the tube supply fixes the tube as its free end section is drawn back. ADVANTAGE- Effective opening of the foil tube even if it is sticking together in its central area.
