ABSTRACT:
A device for winding up a foil web, particularly a foil web of synthetic material, into a foil roll on a roll core, has two swivel arms having roll-core receiving portions at their ends, a contact roller, and an actuating cylinder-piston arrangement for the swivel arms and the roll core drive. The swivel arms are swung according to the indication of the increasing diameter of the foil roll. In the area of the contact roller, a winding device with two swingable winding arms is arranged. A roll-core magazine is assigned thereto, having two magazine disks, which are oppositely located and rotatable about a horizontal axis and have corresponding receiving portions for the roll-core ends. To each magazine disk, a basically L-shaped guiding element is assinged which on the vertical flank of the L has an arched leading edge following the path of the roll-core receiving portions, which--over an assembly trough--continues with a downwardly inclined level which is a discharge edge. The winding device has winding arms swingable about a horizontal axis, which for the purpose of introducing a new roll core coming from underneath, grasp the ends of a roll core located in the assembly trough with their receiving ends and, by entraining the magazine disks and by winding the sectioned foil web over the inclined plane, bring it into contact with the contact roller, where the swivel arms of the device receive the roll core, whereby a further roll core of the roll-core magazine reaches the assembly trough.
