Title: Improvements in and relating to intermittent feed mechanism for printing and like machines
IPC: B65H23/24
Filed: 1946-10-31
Abstract: 618,188. Feeding webs; feeding sheets. JONES. K. W. Oct. 31, 1946, No. 32350. [Class 100(i)] Intermittent feed mechanism for advancing webs or sheets to printing and like machines comprises a feed unit having rotary segments 2 which as shown in Fig. 1 feed a web 1 when the segments 2 engage a rotating suction roller 3 which is constructed as described in Specifications 559,388, 570,795, or 598,148. The roller 3 constantly tends to advance the web which is, however, restrained by contact with a normally stationary suction roller 10. Just prior to the engagement of the segments 2 with the web, the roller 10 is moved in a direction to advance the web by means of a cam 17 on the shaft of the roller 3 which oscillates a lever 14 on the shaft of the roller 10. The suction boxes 8, 11 may be connected to a common exhaust device. In a modification the roller 10 may be driven from the shaft of the roller 3 by Geneva gear, and its intermittent motion may continue after the segments 2 go out of action so that the stopping of the web is controlled positively by the roller 10. The roller 3 in this modification may be a suction roller, or a plane roller engaged by spring-pressed narrow rollers mounted in pivoted arms. In Fig. 4, the suction roller 10 is replaced by a vacuum bar 28 carried in pivotally mounted arms 29 oscillated by a cam 17 on the shaft of a plain feed roller. The web is constantly kept under tension by a rotating suction roller 31 arranged in advance of the roller 3 and segments 2. A valve may be used to cause the suction effect on the roller 10 or bar 28 to be reduced while the segments 2 are in action. When used for feeding sheets the rollers 10, 3, or bar 28 and roller 31 are arranged close together, and front lays are arranged in front of the roller 3 or roller 31, and are raised before the segments 2 come into operation. In some cases back lay fingers are used.
