Label inspection slitter/rewinder
Abstract
Abstract This invention provides a web processing device which has an unwinding mandrel and a rewinding mandrel, and is adapted to receive rolls of web on the former and rewind the web on the latter. Between the mandrels, the unwinding web is made to follow a path which brings it sequentially to a web inspection location and a splicing location. Braking means are provided for halting the movement of the web along the path. The distance along the path between the web inspection location and the splicing location is long enough to permit the braking means to halt the movement of the web before a given point on the web can move the full distance from the web inspection location to the splicing location. In this way, there is no need to provide reverse drive facility on the unwinding mandrel for the purpose of moving the web backwards should a faulty section detected at the inspection location over-shoot the splicing location.
