ABSTRACT:
System for cutting a travelling web (20) of paper being wound on a spool (24) and transferring the cut edge to an empty spool (27) to continue the winding; the system including a drive roll (36) for pulling a cutting tape (33) from a supply source (35) and propelling it through a guideway (30) underneath the travelling web (20) of paper from a near end to a far end just short of the nip (29) between the roll (24) of paper being wound and an empty spool (27) to begin winding; an applicator (46-50) for applying a short length of adhesive to the forward end of the tape before it is propelled to the far end; a sensor (51, 52) determines the passage of the forward end of the tape (33) through the guideway (30) toward the far end; another sensor (53, 55) to detect whether a short length of adhesive is present or absent from the forward end of tape; a brake (59) to clamp the tape (33) and prevent the forward end from advancing to the far end of the guideway (30) while the remainder of the tape (33) behind the brake (59) is diverted into a temporary storage area (69) for a large loop of the cutting tape; a cutter (41) to cut the tape to an appropriate length to perform the operation of cutting the web (20) of paper; and a guideway switch (65, 66) to shunt off to a waste collection area a length of cutting tape (33) having no adhesive on its forward end.
