Reinforcing element for e.g. wiping roll in sanitary application, has rigid or semi rigid element formed of rings that are maintained on turns of roll such that rigid or semi rigid element is separated from roll, while driving turns of roll

摘要

The element has a rigid or semi rigid element arranged around an axis of a tissue paper roll (1) e.g. wiping roll, at the proximity of flat flanks (4), where the element is made of recyclable material i.e. cardboard. The rigid or semi rigid element is formed of rings (31, 32) that are maintained on internal turns of the roll such that the rigid or semi rigid element is separated from the roll by a traction effort along the axis of the roll, while driving the internal turns of the roll, where the width of the rings is less than half of the width of the roll.
