Definitions

  • the invention relates to a device on a spinning preparation machine, for. B. card, stretch or the like, for guiding and compacting a fiber structure at least one sliver, in which at least two funnel-like in a row Guide elements are present, which have several wall surfaces in a row which the fiber structure slides along and is brought together, with between the inlet opening and the outlet opening have at least one wall zone in which the fiber structure is connected to the outside air via an opening stands.
  • the two are at right angles to each other opposite wall surfaces each on one side with a third Wall surface connected while the other, this opposite side as through opening is formed, d. H.
  • the guide element is on one side open.
  • the two opposite wall surfaces of the guide elements are - seen one behind the other - aligned parallel to each other.
  • the pile funnel points closed wall surfaces on all sides. This device bothers that inside of each guide element the compression of the fiber material and the result of Compression of air emerging from the fiber material are asymmetrical. This also takes place with respect to the two funnel-like guide elements Compression and the air outlet asymmetrical to each other.
  • one carding machine is used by two nip rollers wafer-thin, about 1 m wide, undensified fiber pile delivered by a only guiding element is passed down.
  • the guiding element exists corresponding to a training of only two and according to another Formation from four opposite wall elements.
  • the four Wall elements are arranged side by side and in such a way that all four Wall elements without opening with the outside air form a closed structure. In neither embodiment is an arrangement of two provided one behind the other guide elements.
