Abstract
A device for winding webs of material onto winding shafts comprises a movable bearing supporting a winding shaft during winding, through which the supply roll being formed can be moved towards a contact roller and which can be moved in a position away therefrom for the removal of the completely wound supply roll. A new winding shaft accelerated approximately up to the speed of the web and onto which the cut leading end of the web can be wound, is inserted in the movable bearings. To prevent damage to the web, the weight of the supply roll is supported on the contact roller. The movable bearing is formed by two pairs of holding means, each pair of which can be moved synchronously with the other pair but also independently thereof. The pairs are adapted to hold a supply roll jointly as well as individually to hold a completely wound supply roll or a winding shaft with the leading end of the web wound thereon.
