2092908 9205959 PCTABS00011 A rotary label die cutting apparatus and process comprises a servo motor (24, 70) driving either a rotary die cutter (20) or its backup roll (26), preferably the latter, a servo motor driven roll (30) pulling a web (10) carrying the labels (11), under the die cutter (20) and an electronic processor (40), controlling the relative position and speeds of the die cutter (20) and web (10) through commands to the servo motors. The apparatus includes means for observing eye marks (14, 15) on the web (10) and the angular position of the die roll (20). This apparatus has the unique ability to control the cutting action while the cutting is taking place. Labels of different lengths can thus be generated from one die (21, 22).
