Shaft handling (Vorwald)
Expansion shaft pullers for Vorwald shafts and other brands
Vorwald shaft pullers (EA) are utilised in numerous different versions in all branches of the paper, plastic, metal foil and laminate materials processing industries. Constantly increasing reel weights and dimensions, automated production sequences and stricter regulations regarding work safety have led to the increasing replacement of manual handling of expansion shafts by automated shaft pullers. Shaft handling devices serve for pulling the expansion shafts out of the finished reel and for introducing them into the core. Further functions such as automated core loading from the core magazine or pick up and removal transportation of the finished reel, are available and can be included as one complete turn-key package.
Features and advantages
- Many years of experience in handling expansion shafts
