Definitions

  • the present invention relates to a knitting machine comprising at least one needle bed in the grooves of which are housed sliding needles having at least one heel capable of occupying two levels relative to the plane of the needle bed, one in which the heel can be driven by the cams of the cam holder and the other in which the heel is out of the path of these cams, means for acting on said heels to put them in the positions corresponding to these two levels, one of these means being constituted by a cam pushing the heels back into their low level, and keys associated with each needle to bring them into the working position, in which they can be driven by the working cams.
  • the needles are provided with an elastic extension in the form of a hairpin, which may or may not come in one piece with the needle itself.
  • the end of this pin carries the heel of the needle.
  • the pin By means of a cam, the pin can be bent and by pulling it back a span of the pin is hooked behind a special bar so as to keep the heel in the submerged position.
  • the bend of the elastic pin however constitutes a weak point, even if this pin or the entire needle, in the case where the needle and the pin came in one piece, is made of high strength steel. In any case, such a needle is expensive to manufacture.
  • the present invention aims to achieve a retraction of the heels of the needles out of work by more robust and reliable means, using neither elasticity, nor delicate articulation.
  • the knitting machine concerned can be either a straight machine with one needle bed or two needle beds or a circular machine.
  • the needle bed 1 is shown in a horizontal position, but it is obvious that it is used in the inclined position.
  • a groove 2 in which is housed a needle 3 provided with a hook 4 well known per se and a heel 5 at its end.
  • the needle 3 is guided between the bottom of the groove and a bar 6, also known per se, extending all along the needle bed.
  • Each needle 3 is pushed into the working position by a key 7 of special shape, capable of occupying several levels in the needle bed and associated with an auxiliary key not shown forming part of an individual selection device described in detail in the patent CH 632 024, in which the key 7 is designated by the reference 8.
  • the bottom of the groove 2 has a first part 8, at the hook 4 of the needle, corresponding to the usual bottom of such a groove, this first part 8 being followed by a first shallow depression 9 of uniform depth with the exception of the part which connects it to part 8, this first depression 9 being followed by a second depression 10, deeper at the heel 5 of the needle.
  • This second depression 10 can be machined in each groove 2 or alternatively be made up of a single countersink extending over the entire length of the needle bed.
  • the needle 3 for its part, has a clearance 14 over a part of its length, consisting of a narrowing of its height, so that the lower edge of the needle, constituting said clearance, is oblique relative to the two sides 15 and 16 rectilinear and parallel with a conventional needle.
  • This clearance 14 extends in the direction of the heel 5 to an oblique bent part 17 connecting the body of the needle 3 to the heel 5.
  • the lower edge of this part 17 is substantially parallel to the ramp 18 which connects the depressions 9 and 10 from the groove.
  • the lower part 19 of the connection between the heel 5 and the body of the needle constitutes a sliding shoe.
  • the non-rectilinear connection between the heel and the body of the needle provides a certain elasticity, sought after, damping the transmission to the hook 4 of shocks on the heel 5.
  • the heel 5 has, on the side of the key 7, at the level of the body of the needle, an oblique ramp 20 lying below a portion 21 perpendicular to the plane of the needle bed.
  • the end of the key 7 also has a ramp 22 parallel to the ramp 20 of the heel 5 when the key 7 is in the selected position, that is to say in the high position.
  • the key 7 ends with a front face 23 perpendicular to the plane of the needle bed.
  • the key 7 also has a heel 24 and is retained in the high position by a second steel wire 25 extending over the entire length of the needle bed, this wire further retaining the heel 24 of the key in the withdrawn position. or preselection.
  • the heels 5 of all the needles are first embedded in the needle bed 1 by a special cam 26 secured to the cam carrier not shown.
  • the keys 7 are, at rest, in position 24 '.
  • the corresponding key 7 is released, as described in patent CH 632 024, and comes into position 24 ′, while the keys of the unselected needles are retained in position 24.
  • the selected key is then driven by a cam of the cam holder shown diagrammatically at 27, and its end abuts against the heel 5 of the corresponding needle by its front face 23, as shown in 24 ''.
  • the needle 3 is pushed forward and its bent part 17 abuts against the ramp 18 on which the shoe 19 rises to pass over the part 9 of the groove as shown in Figure 2.
  • the ramp 22 of the key 7 slides on the ramp 20 of the heel 5, thereby helping to lift the heel while continuing to push the needle.
  • the heel 5 protrudes from the needle bed and can be gripped by the working cams of the cam holder.
  • the felling of the needles is represented in FIG. 3.
  • the heels 5 of the needles are driven behind by a felling cam 28.
  • the heels 5 arrive opposite the depression 10, it is advisable to prevent these heels from fall prematurely into this release.
  • the heels 5 are supported until the end of their felling stroke by the keys 7, the heels of which are guided by a cam 29 of the cam holder.
  • the two cams 28 and 29 somehow form a channel of uniform width, in which the needle-key assembly is guided as if it were a single piece.
  • the keys 7 then continue on their own to the right by freeing the heels 5, to return to their initial rest position 24 '(FIG. 1).
  • the embodiment described above by way of example is of course susceptible of numerous variants.
  • the clearance 14 of the needle is theoretically optional.
  • the bent part, 17-19 of the needle could have a regular curvature or not instead of a straight part 17.
  • the depression 10 of the groove could be obtained by a complete interruption of the needle bed.
  • the heels could be held magnetically in their position embedded by magnets, for example by a strip of plastic material containing ferrite particles.
