Definitions

  • the invention relates to a feed device according to the preamble of claim 1.
  • sliver processing machines for Example of wrapping machines, respectively a group of slivers are fed to a drafting unit, which is above a feed table for the Winding machine is located. Usually there are two or three such drafting units in a row above arranged the feed table. The individual slivers are made from cans over a jug assigned role deducted and the respective drafting unit fed. The jugs are in rows next to the Feed table set up. That means the feeding of the slivers takes place transversely to the longitudinal direction of the feed table.
