Abstract

Improvements in the motor shafts for winding webs of sheet material, characterized in that the shaft maintains firm contact with a number of cores for rolls of said material distributed along a through axis and moved by means of friction devices, said cores at intervals along the tree and being fixed on the shaft by expandable expansion devices radially driven from one end or both ends of the shaft, said shaft having expansion rings suspended on the through shaft to carry each individual core or a small number of cores located side by side, said expansion rings having radially expandable sections for fixing the cores, and each expansion ring being connected non-rotatably with friction devices projected to rest on the shaft with a constant pressure.
