Definitions

  • the subject of the present invention is a method of transferring a knitted fabric from the needles of one of the needle beds of a rectilinear knitting machine onto a comb-magazine located under the needle beds, according to which the last ones are passed first. knit stitches on a transfer comb, then this transfer comb on the store comb.
  • the curved ends of the needles of the transfer comb are placed at the height of the hooks of the knitting needles, the laterally curved end of these needles of the transfer comb also engaging the hook of the knitting needles.
  • the needle bed rises and the knitting needles descend, slightly driving the ends of the needles of the transfer comb, the stitches, under the effect of traction on knitting, sliding knitting needles over the needles of the transfer comb.
  • the knitting stitches are on the top of the bent part of the transfer needles, or even beyond this top, on the side of the end. It is a critical point from which the stitches risk to slip on the wrong side of the bent end of the needles of the transfer comb and consequently to escape from these needles.
  • the vertical component of the pulling force of the knitted fabric on the transfer needle is much greater than the tangential component which makes the stitches slide on the needle and the stitches like the transfer needles are highly stressed.
  • the present invention aims to overcome the drawbacks of the known method using a transfer comb.
  • the method according to the invention is characterized in that the transfer comb is brought between the needles carrying the stitches of the knitted fabric to be transferred and the knitted fabric to be transferred.
  • the very slightly bent end of the needle of the transfer comb is brought against the inclined plane, then the knitting needle is lowered by pushing the transfer comb slightly upwards simultaneously.
  • the needles of the transfer comb then engage in the grooves of the knitting needles and pass through the stitches.
  • the needles of the transfer comb come to the end of the knitting needles, without crossing them, then the knitting needles, by withdrawing, release the stitches which can then slide freely and practically vertically along the needles of the transfer comb.
  • the transfer comb is simple, the knitting of knitting needles on the transfer comb is quick and natural and the transfer process can be done quickly.
  • the invention also relates to a device for implementing the method according to the invention, for the transfer of knitting needles from a knitting machine comprising needles provided with a groove in their short underside, for their carry over mesh, a movable transfer comb, a magazine comb and means for pushing the mesh of the transfer comb onto the magazine comb, characterized in that the teeth of the transfer comb are formed by needles with thin ends and slightly curved being able to penetrate into said grooves of the knitting needles to come and take the stitches between the knitting needles and the knitting to be transferred.
  • Figure 1 is a sectional view of the upper part of the needle beds of a knitting machine showing the transfer comb in the approach position.
  • Figure 2 is a similar view showing the transfer comb in the gripping position of the stitches of the knitted fabric to be transferred.
  • Figure 3 is a similar view showing the comb at the time of passage of the mesh on the transfer comb.
  • FIG. 4 represents the position of the transfer comb at the time of the transfer of the knit on the magazine comb.
  • Figure 1 we recognize the upper part of a straight knitting machine having two needle beds 1 and 2 provided with grooves 11 and 21 in which move the knitting needles. Only needle 3 of needle bed 1 has been shown for the purposes of the description.
  • the groove 21 naturally includes a analog needle, but not involved in the comb transfer process.
  • Needle 3 is of the standard type. It has a hook 31, a valve 32, a shoulder 33, a groove 34 formed by a milling in the thickness of the needle, on the small lower side of the latter, milling opening into a lateral clearance 35 in the form of inclined plane.
  • the teeth of the transfer comb partially shown, consist of needles 4 provided with a thinned end, slightly curved 41 whose thickness is equal to that of the hook 31.
  • the needles 3, carrying the knitted fabric 5, are pushed forward in their extreme position of transfer of stitches, the knitted fabric 5 being retained by the shoulder 33.
  • the bed 1 is slightly withdrawn, that is to say lowered, to make room for the transfer comb which rises between the bed 1 and the knitted fabric 5, so that the ends 41 of the needles 4 of the transfer comb come to the height of the needle clearances 35.
  • By a slight lateral movement of the transfer comb it is ensured that the ends 41 come into contact with the recesses 35.
  • the grip of the knitted fabric by the transfer comb is shown in FIG. 2.
  • the transfer comb being in the same position as in FIG. 1, the needles 3 are pulled down in the direction of the arrow F2.
  • the tips 41 of the needles 4 of the transfer comb penetrate into the grooves 34 of the knitting needles.
  • the knit 5 descends with the needles 3 and the last stitches 51 of this knit engage around the points 41 of the needles of the transfer comb.
  • the transfer comb descends to come in front of a magazine comb whose tips 61 of the teeth 6 come to engage in the grooves 42 of the needles 4 of the transfer comb, as shown in FIG. 4, in such a way that the knitted fabric can be transferred from the transfer comb to the store comb by means of a rake-shaped pusher mounted sliding on the transfer comb.
  • the teeth 4 of the transfer comb are provided with grooves 42 in which the ends of the teeth 6 of the comb-magazine come to engage for the transfer of the knitted fabric on the comb-magazine.
  • the transfer comb is advantageously guided by its ends in two slides and performs a back-and-forth movement between the knitting needles and the magazine comb.
