1299022 Winding webs BUTLER AUTOMATIC Inc 10 Aug 1971 [14 Aug 1970] 37518/71 Heading B8R Web winding apparatus comprises stationary standards 40 constituting a normal winding station for a web roll 38 rotated by means of mandrels (48, 52), one of which is driven (Figs. 6, 7 and 9, not shown) carried by movable arms 54 pivoted at 58 in floor-mounted blocks 60. An arbor with adhesively prepared winding cores 44 is carried by pivoted arms 146, and a knife (178), Fig. 5 (not shown), is mounted on further pivoted arms 158. When the roll 38 has reached its required diameter a switch (not shown), is operated, the drive is stopped, the roll is braked, and the web comes to a standstill, surplus web being accumulated in a storage festoon 20; the arms 158 are then lowered and the arms 146 raised to cause the knife to sever the web and to attach the new end of the web to the replacement arbor. As soon as the roll 38 stops the mandrels are disengaged, the arms 54 are pivoted to a generally vertical position (Fig 3, not shown) and the replacement arbor is then gripped by the mandrels. Winding of the new roll is commenced in the arbor position whilst the completed roll is removed from the standards 40 and the arms 54 are then pivoted to transfer the new roll to the standards 40 without interrupting the winding operation.
