Definitions

  • the invention relates to a needle for a textile machine, in particular a felting needle or fork.
  • Such a needle is for example from the US 2,857,650 B known.

  • a needle board is out of the DE 3105358A1 known.
  • a needle bar of the needle holder is placed on top of the needle board and presses on the holding means of the needle butt. If the holding means is not bent at right angles to the longitudinal axis, a punctiform contact or a contact with only a very small contact surface is created between the needle bar and the transverse part. This can damage the needle bar.

  • an improved needle is to be created, wherein in particular the contact between the needle bar the needle holder of a textile machine and the needle to be optimized.
  • a working section, a lower or first shaft section, and an upper or second shaft section are arranged coaxially with respect to a longitudinal axis, which runs essentially in the direction of movement of the needle.
  • This coaxial arrangement of the three sections results in a sufficient stability of the needle, even when working at high speeds.
  • the needle foot is formed in the form of a holding means comprising two legs. The two legs of the holding means project from the longitudinal axis of the needle in two opposite directions away from each other.
  • the holding means of the needle butt extends in a straight line radially to the longitudinal axis of the needle in the transverse direction and is arranged transversely to the longitudinal axis of the needle.
  • This holding means of the needle butt thus extends away from the longitudinal axis.

  • the longitudinal axis of the holding means of the needle foot defines a transverse direction.
  • the longitudinal axis of the holding means of the needle butt or the two legs and the longitudinal axis of the needle are preferably arranged at a right angle to each other.

  • the holding means can also be made without cutting by tensile, compressive or shear forming in a simple manner, so that even difficult to bend materials can be used in the manufacture of the needle.
  • the buttress of the needle butt and the upper shaft portion of the needle may form a T-shaped retaining portion of the needle which serves to support the needle in a needle holder.
  • the holding means may preferably be symmetrical with respect to an imaginary plane of symmetry, which spans along the longitudinal axis of the needle and transversely to the longitudinal direction of the holding means in a so-called width direction.
  • the needles can be particularly space-saving in the needle holder of a textile machine order. A force on the longitudinal axis of the needle is ensured.

  • the grooves provided on an upper side of the needle board, in which the holding means of the needle butt are in the position of use of the needles, can have a narrow width corresponding to the holding means, so that more grooves can be provided on the needle board.
  • the cross section of the holding means of the needle butt in a preferred embodiment has a different from a circular contour cross-sectional shape.
  • This may for example be oval, elliptical, polygonal and in particular rectangular or hexagonal or triangular.
  • corner or edge regions of the holding means can be provided with a radius or arched, so that a corner or edge-free lateral surface results on the holding means.
