  • Patent number: 6044639
    Abstract: An automatic spinning start-up flyer for a roving frame which has on a flyer arm a swingably-mounted pressing finger comprised of a pressing finger bar and a pressing finger arm with a pressing finger blade. The pressing finger assembly is mounted on a pivot axis at the centrum of the connection of the pressing finger with the flyer arm and is rotated about the bobbin center. The pressing finger rod lies outside the radius along which the pressing finger arm with pressing finger blade are arranged and the pressing finger bar is actuatable by an actuating element effective transverse to the pivot axis upon the pressing finger bar to swing the pressing finger into its outwardly-swung position. With the flyer, a wide opening of the pressing finger can be effected automatically for automatic bobbin change without a loading of the pressing finger against the sleeve or bobbin.

  • Patent number: 5040765
    Abstract: A support system comprises a cantilever for taking up objects running on roller wheels. The cantilever is formed to roll the objects onto the cantilever in a first direction up to a lock position and to remove them from the cantilever by rolling in a substantially opposite direction. The roller wheels shall be locked in a rest position and removal of the objects by rolling the roller wheels from the cantilever shall be eased. In order to achieve this object the cantilever comprises a depression formed at the lock position of the roller wheels and extending transversely to the roll-on direction. A substantially plane portion is provided at the roll-on side of the depression and a roller wheel arriving in the depression contacts said plane portion.
