ABSTRACT:
A system and method for cutting continuous web that provides a simplified and direct feed path during loading, and thereafter a more-complex serpentine feed path at an infeed unit for reliable infeed of the web, arranged as either a free loop or a moderately tensioned configuration. Downstream, an indexing drive intermittently pauses the web for the cutter knife to operate. The indexing drive and infeed unit's drive are synchronized by a controller to produce a small horizontally disposed buffer loop therebetween. The buffer loop is maintained within a predetermined range using a sensor, operatively with the controller, that measures the location of the end of the loop, modulating the drives to maintain the buffer loop's (returning) end within a predetermined location about the sensor's sensing field. The system includes an adjustment drive motor for moving a plurality of edge guide sets toward and away from each other in synchronization.
