Abstract
Lowering mechanism is disclosed for the foil roll in a device for the winding of a foil web, particularly a synthetic-material foil web. A roll core with the finished foil roll can be received at its ends by lowering arms. It can be deposited on a discharge level by means of a lowering-arm drive. The lowering arms can again be raised with the aid of the lowering-arm drive. For each of the lowering arms, the lowering-arm drive has a lowering cam plate, these being identically built, congruently arranged and provided with an outer leading edge, which is basically shaped as a numeral 6. The lowering arms are guided on the leading edge by means of a guide element. The lowering cam plates are driven by a simple electromotor.
