Definitions

  • the knitting tool mentioned at the outset is characterized according to the invention in that the hook, starting from a maximum value of the cross-section in the region of the neck, towards the end of the hook or at the beginning of the hook tip, with a cross-section which is continuously tapering in both cross-sectional dimensions, is formed such that all cross-sectional areas at least the hook in the areas of the taper are similar to one another and that its side-limiting edges, while maintaining the rectangular shape, are rounded or chamfered at least in the areas of the taper.
  • each rectangular cross-sectional area in the region of the taper points with its longer sides either in the direction of the width dimension or the height dimension.
  • the latter training is particularly advantageous in view of the lateral thread clearance.
  • any rectangular cross-sectional area in the area of the taper can also be square.
  • the punched latch needle shown in FIGS. 1 to 6 has a needle shaft 1 which merges into the needle face 2 with the maximum needle face height indicated at 3a. This is followed by the molded-on needle neck 4, which is finally followed by the curved needle head or hook 5.
  • a tongue slot 6 is worked out, in which a needle tongue 7 is pivotally mounted about a tongue axis 8, as can be seen from FIG. 1, in which the tongue 7 is illustrated in the closed state and, in dashed lines, in the open state.
