Definitions

  • the invention relates to a provided for knitting machines latch needle with a needle tongue, which is pivotally mounted in a tongue groove of the latch needle and has a tongue shaft, a tongue spoon and a transition region between the tongue shaft and the tongue spoon.
  • a tongue tongue is used to open and close a hook space of the latch needle, which is mounted at a pivot point in the needle shaft of the latch needle.
  • This needle tongue is actuated by the mesh, which is located either in the hook space of the latch needle or on the needle shaft behind the needle tongue.
  • the latch needle is expelled.
  • the mesh located in the needle hook slides on a needle neck of the latch needle in the direction of the needle shaft. This movement pivots the needle tongue to its open position. Then the stitch slides over the tongue shaft and over a tongue spoon and then passes from the tongue spoon to the back of the needle.
  • the latch needle is retracted so that the mesh can be dropped.
  • the stitch which is located on the back of the needle behind the needle tongue, slides in the direction of the needle hook. By this movement, it pivots the needle tongue in its closed position. Upon further needle movement, the stitch slides over the tongue shaft and the tongue spoon and passes over the needle hook in their mesh.
  • a part of a latch needle according to the teaching of the prior art is in the Fig. 2 shown.
  • the known latch needle is in the open position comparable to the latch needle according to the invention Fig. 1d ,
  • a needle tongue 20 is pivotally mounted at a pivot point in the needle shaft 21 .
  • a transition region 22 between a tongue shaft 23 and a tongue spoon 24 has a breast region with a width seen transversely to the longitudinal direction of the latch needle, which is identical with respect to the width of the back region of the tongue Transition area is.
  • the transition region 22 has a small extension and is relatively abrupt.
  • the US 2,282,824 describes a latch needle, the tongue but has no spoon, but engages in a notch in the needle hook.
  • the tongue widens towards the tip.
  • a latch needle which has a leaf-shaped tongue shaft, to which a spoon is attached, which engages around the shaft laterally and is rounded in these areas. however, the shank overhangs these lateral spoon areas, allowing the edges of the shank to break the stitch.
  • the invention has for its object to reduce the sliding resistance of the mesh in the transition region from the tongue shaft to the tongue spoon.
  • the width of the transition region tapers transversely to the longitudinal direction of the needle tongue, starting from the tongue spoon in the direction of the tongue shaft.
  • the contact surface for the mesh widens continuously from the tongue shaft to the tongue tongue width to avoid a sudden transition.
  • another embodiment may have a tongue back with a transversely to the longitudinal direction of the needle tongue extending width of the transition region, which is smaller than the corresponding width of a tongue breast of the transition region.
  • Fig. 1a to 1d and Fig. 2 is the part of a latch needle relevant to the invention shown, namely the end of the latch needle, ie where a needle tongue acts.
  • a latch needle 100 has a needle shaft 1, a fixed to the needle shaft 1 needle hook 2 and a needle tongue 3 , which is pivotally mounted at a pivot point 4 .
  • the needle tongue 3 comprises a tongue shaft 5 , a tongue spoon 6 and a transition region 7 between the tongue shaft 5 and the tongue spoon 6.
  • the transition region 7 is formed identically on both sides of the needle tongue 3 and extends in the longitudinal direction of the needle tongue 3 between a shaft end 8 and a Spout end 9 and transversely to the longitudinal direction between a tongue chest 10 and a tongue back 11th
  • the edges of the transitional region 7 are determined transversely to the longitudinal direction by the tongue breast 10 and the tongue back 11 and result in the longitudinal direction from the arrangement of the tongue spoon 6 and the pivotable mounting 4.
  • the transition region 7 therefore has a parallelogram-like shape in side view and plan view.
  • This form has at the tongue breast 10 the starting point 12 , at which the tongue shaft 5 emerges from a tongue groove 19 when the needle tongue is closed, and an end point 13 , which is given by the wall thickness of a groove 14 for the needle hook 2.
  • this form has a starting point 15 (FIG. Fig. 1c ), on which the tongue shaft 5 emerges from the tongue groove 19 when the needle tongue is open, and an end point 16 , which in turn is given by the wall thickness of the groove 14 for the needle hook 2.
  • the transition region 7 tapers in its transverse width to the longitudinal direction of the needle tongue 3, starting from the LöfFelende 9 of the tongue spoon 6 to the width of the tongue shaft 5, the transition region 7 has a back portion 17 with a smaller width compared to a chest region 18 (FIGS. please refer Fig. 1d ) on.
  • Fig. 1b shows a view of the tongue back of the needle tongue 3, the tongue shaft 5 is partially received in the tongue shaft 1 formed in the tongue groove 19 .
  • Fig. 1d The view of the tongue breast 10 according to Fig. 1d shows that the transition from the tongue shaft 5 to the tongue spoon 6 on the side of the tongue chest 10 is formed relatively flat. In Fig. 1d the transition region 7 is again clearly indicated by dash-dotted lines.
