Brilliant technology for a reliable winding quality

This ist how ROBUST friction winding shaft works:

The winding shaft is equipped with rotary friction elements arranged in line and independent from each other which have metal clamp bodies which guarantee a reliable grip of the sleeves. The winding shaft has three horizontally arranged slots. In each slot, there is a flat rubber hose and a pressure rail above. Once the hoses are charged with pressurised air, the friction coatings correspondingly press against the inner metal rings of the friction elements and take the rolls with them.

The shaft works with a lead of 5 - 8 % to the product track. Thus each element has the effect of an individual drum brake, which guarantees a specifically equal winding moment for all rolls on the same shaft even if they have different widths and diameters.
