Definitions

  • the invention relates to a needle holder for a textile machine with a needle board.
  • a needle holder serves to receive needles, such as felting needles or fork needles, and may be used in textile machines, e.g. Felting machines are used.
  • a needle holder with a needle board is for example from the DE 31 05 358 A1 known.
  • the grooves provided in the groove board have a dovetail-shaped cross-section, wherein the groove width seen transversely to the direction of the grooves in the region of the top of the needle board is smaller than the diameter of a foot portion of a needle which projects into the groove in the position of use of the needle. This is to prevent accidental dropping out of the needle from the needle board.

  • the needle foot which is arranged at one end of the needles, has a holding means, which protrudes into the needle inserting the needle into the corresponding hole passing through the groove.
  • the holding means ensures that the needle is held securely in the needle board. It serves to hold the needle in the needle board in the direction of its longitudinal axis and in the direction of the central axis of the bore and for specifying the rotational position of the needle about its longitudinal axis.
  • the diameter of the bores which receives a region of the needle shaft is greater than an average value of the groove width or greater than the groove width in the region of the groove base. This makes it possible to arrange the grooves closer together, without affecting the stability of the remaining between the grooves Nutenstege in the needle board.
  • the holes of two adjacent grooves can be seen offset in the direction of the grooves arranged to each other.
  • the center axes of the holes are arranged in the direction of the grooves spaced from each other. This makes it possible to arrange adjacent grooves even closer together.
