ABSTRACT:
An apparatus of the type for the supply of webs to a processing station is described, in which by means of a controllable drive mechanism, each of several webs is advanced to the processing station in superimposed guide channels. The front portion of the web, following processing, is cut from the web and the front end of the web, following separation, is retracted out of the processing station. For this purpose, the controllable drive mechanism can be selectively engaged with one web in the vicinity of the guide channel of the web for the complete forward and return transport of the web before and after a processing operation. The drive mechanism preferably has reversibly drivable rollers. For producing an engagement between a web and a drive roller the guide channels are preferably pivotable with respect to the rollers. The processing station is generally a printing means, in which, for example tickets of differing color are to be printed.
