Abstract
Apparatus for cutting and moving a leading end of a web, including a frame (70, 186); a crank (188) mounted for rotation on the frame; an upper platen (210); a pair of linear guides (212) for the upper platen; a first crank arm (196) connected between the upper platen and the crank; a lower platen; second and third crank arms (218, 220) connected between the lower platen and the crank; an upper die shoe (262) mounted to the upper platen; a lower die shoe (260) mounted to the lower platen; a pair of linear guides (264) between the die shoes; a slide (96) mounted on the frame; a shuttle arm (98) mounted on the slide for movement between the die shoes; an actuator arm (114) pivotably connected to the shuttle arm; a vacuum head (88) pivotably mounted to the shuttle arm; a cam follower (144, 146) connected to pivot the vacuum head; a cam (148, 158) pivotably mounted to the frame for engaging the cam follower; a link (258) rigidly connected to the cam; a fourth crank arm (252) pivotably connected between the link and the crank; and a drive system (287-304) for rotating the crank and oscillating the drive arm. The shuttle arm is moved back and forth on the slide by the actuator arm and the vacuum head is pivoted by the first link to grip the web as the upper and lower die shoes move toward each other to cut the web, in synchronism with movement of the upper and lower die shoes.
