Abstract
Abstract A system (50) includes a labelling machine (52) and a digital data processing system (54) connected to the labelling machine (52). A cutter (56) of the labelling machine (52) has a shaft (58) with a mark (60), which is sensed by a sensor (62). The sensor (62) supplies shaft (58) information on line (3) to digital data processing system (54). The digital data processing system (54) supplies control signals on line (64) to feed roll (66) stepper motor (67). The digital data processing means (54) is also connected to an optical sensor (76) by line (78). The optical sensor (76) senses the position of position mark (74) on the labels (70), which is correlated with the position of shaft (58) in order to feed the labels (70) to the cutter (56) at the proper rate so that the labels (70) are always cut at the kerf (72) between each label (70).
