Abstract
A system and method for detecting and diverting sections of web having splices on a continuous web is provided. A splice detector is located adjacent a source of continuous web, typically a roll. The movement of the web from the roll is tracked, and the relative location of the splice within the web stream is noted by a controller. Downstream, a web utilization device is provided with a movement detector also connected to the controller. Movement of the splice-containing section through utilization device is tracked so that the splice-containing section is not processed by the utilization device, or is reprocessed on a non-splice-containing section. A cutter is also provided with a movement detector, also connected to the controller. Movement of the web from the utilization device to the cutter is tracked and the section containing the web is cut. A diversion mechanism can be used to remove the cut section of web containing the splice so that it does not appear in the final stream of finished cut sheets.
