Abstract
Web from a depleting roll of web in use is directed along a vertical line by rollers. A knife member is mounted for movement across the line and has a knife edge on its lower surface to cut the web. Vacuum ports are provided on each side of the knife member to hold the end of a spare roll which is trimmed flush with the knife edge. A piece of tape is applied to and overlaps the end of the spare web. The spare web end is positioned on the side of the knife member facing away from the line. A pair of cutting plates are positioned on opposite sides of the line below the knife and are movable vertically. Tape pressing bars are pivoted to the plates. The plate on the opposite side of the line from the knife is positioned with its top edge aligned with the knife edge. The other plate is spaced from the knife edge so that the bar acts against the tape applied to the spare web end. The web is stopped during the splicing operation by a clamp carried by the lower plate and by a pair of nip rolls locked against rotation. The knife member is moved across the line to cut the tape in use and butt the end of the spare web thereto. The tape press forces the tape against the cut end of the web in use. The clamp is released and the nip rolls unlocked. A second piece of tape held to one of the nip rolls by vacuum is applied to the other side of the splice as the web moves past the rolls.
