Title: Tucking means for a web-winding machine
IPC: B65H19/28
Filed: 1961-11-02
Abstract: 1,000,946. Winding webs. CAMERON MACHINE CO. Nov. 2, 1961 [Jan. 17, 1961], No. 39317/61. Heading B6B. A tucking mechanism for starting the leading end of a web on an empty core, particularly in a winding machine as described in Specification 898,386, has two rollers 76, 78 mounted between a pair of slide members 86, slidably adjustable in the slots 84 of a pair of suspension arms 81, keyed to a shaft 80. A cam-plate 98, Fig. 3, with two cam surfaces 108, 106 is adjustably attached to the frame of the winding machine. An arm 122, Fig. 12, is fixed to the shaft 80 and a plate 118 with a cam follower 120 is rotatably mounted on the shaft. An adjustable abutment screw 126 is attached to the plate 48 through a lug 124. The arm 122 is biased toward the screw by a spring 130. The shaft 80 and the riding roller 38 are rotatably mounted between a pair of vertically movable carriages 40. When a full roll 36F has been removed from the winding drums 20, 22 to the unload arms 46 and new empty core 36N has been positioned by load arms 62 between the stationary drums 20, 22, the suspension arms 81 are lowered by the carriages 40 to the position shown in Fig. 3, so that roller 76 urges the web on to the serrated knife edge 74. A brush 68 applies adhesive to the trailing edge 60 of the web, and the leading edge drops on to its drum 20. The load arms 62 are then rotated to the position shown in Fig. 1 so that a cam follower 138 on the roller 76 rides over a cam surface 136, and the suspension arms swing down. During the slow initial rotation of the drums 20, 22, roller 76 riding against the new core 36N and roller 78 riding on the drum 78, induces the formation of a bight 140 which is forcibly tucked into place between the core 36N and the incoming web on the drum 20. The winding machine then continues to operate as described in Specification 898,386. In a further embodiment, the tucking rollers 76, 78 are replaced by a flexible bristle brush 160, the mode of operation of which is illustrated in Figs. 8, 9 and 10. Specification 1,000,947 also is referred to.
