VORRICHTUNG ZUM SCHNEIDEN VON BANDFOERMIGEM MATERIAL

摘要

A strip is composed of a plurality of successive groups of successive strip sections. The strip is provided with end-of-group indications coordinated with the ends of the respective groups of strip sections. The strip is transported backwards along a predetermined path so that each end-of-group marking precedes the first section of the respective group of sections. A detector located at a predetermined position along the transport path detects the end-of-group markings and generates corresponding end-of-order signals. The end-of-order signals are applied to a storage device. In response to each end-of-order signal, the storage device activates a separating device for separating one order from the next. However, the activation occurs only after the elapse of a time delay compensating for the backward transport of the strip. Thus, if prior to such backward transport the strip is transported forward for processing and during such forward transport fed to a take-up roller, the possibility of performing the detecting and separating operations during backward transport of the strip makes unnecessary unrolling and rerolling of the strip for a renewed forward transport.
