Definitions

  • the invention relates to a method for producing the tongue bearing in a latch needle for textile machines, in which, starting from a latch needle with a longitudinal tongue slot arranged in the needle shaft, a needle tongue with an end bearing part is introduced into the tongue slot and positioned in the correct position, whereupon an elongated axle pin is inserted into captive, transverse bores in at least one of the needle shaft cheeks delimiting the tongue slot and in the bearing part of the needle tongue and is captively fixed.
  • a device for performing the described method with the features mentioned at the outset is characterized according to the invention in that it has a device for notching the wire fed to it and means for breaking off individual axis pins on the notches in the axis pin spacing, which are subsequently subjected to a heat or cold treatment Notching in a brittle, broken wire has that between the bearing means of the counter-punch and a die of the clamping means a transversely to the axis of the punch between a receptacle and an insertion position movable transfer element of the break-off means is arranged, the at least one axis pin receiving and this exactly axially parallel to the punching die axis holding receiving means that the transfer element are assigned loading means through which each with an axis pin in the receiving position standing in the receiving means is ringable, and that when the transfer element is in the insertion position, the axis pin held in its receiving means is aligned with its axis to the punch axis.
  • the notched and hardened wire 13 is fed to the device according to FIGS. 3 to 6.
  • This device has a dimensionally accurate support 26 and one to this on one side adjoining die 27, which together with a jaw 28 that is moved toward and away from it forms clamping means for a preassembled latch needle, the needle shaft 1 of which in the area of the needle shaft cheeks 5 in the area from FIGS 6 apparent manner on the support 26 is clamped between the die 27 and the jaw 28.
  • the needle tongue 6 was inserted into the tongue longitudinal slot 4, which is fixed in position in such a way that its bearing hole 10 has a precisely predetermined spatial orientation.
