Expansion couplings (Vorwald)

The Vorwald expansion couplings are an economical alternative for the conventional mechanical constructions utilised for printing labels.

The expansion coupling can be utilised in both winding directions and permits secure clamping both with regard to safe torque transmission as well as securing against axial displacement.

• Very quick conversion to other core diameters
• Small weight of the coupling
• Simple handling
• Take-up bore according to customer specification
• Eminently suitable for narrow webs and thin walled cores
• Different standard sizes: 70, 76, 100, 120, 150, 152 and 152.4mm
