Definitions

  • the invention relates to a transfer needle for a knitting machine, wherein the transfer needle has a needle breast and a transfer spring, in particular Kastenum vonfeder, with a spring chest.
  • Such a Um exchangeadel is for example by the DE 31 45 708 A1 known.
  • this clearance is realized by cap springs, preferably by Kastenum von aggrn, wherein one end of the Kastenum von aggr is firmly connected to the needle body of the transfer needle.
  • the US 4,646,542 describes a latch needle with a separate, lying next to the needle in the needle channel capstan, which is displaceable between an inactive position and a Um yogaposition in the channel. A mesh division is not possible with this combination of needle and cap spring.
  • the Applicant has set itself the task of being able to make a mesh division using a transfer needle with a needle tongue and a trained as Kastenum von cognitive capping spring.
  • a transfer needle with the features of claim 1.
  • the spring breast of the Kastenum von yogafeder in the Um yogaposition is congruent with the needle breast and covered in the mesh separation position part of the needle tongue when it is in the open position.
  • the longitudinally displaceable Kastenum von yoga (transfer needle) from its Um psychologyposition In Position are brought to the mesh parts.
  • the transfer needle is driven out into position to the mesh parts, wherein the mesh to be split opens the needle tongue and comes to rest against the spring breast of the box suspension spring.
  • the stitch can not slip behind the needle of the transfer needle.
  • the further transfer needle take-over needle is then expelled into its entry position into the loop to be divided.
  • the storage and guidance of the box suspension spring can be formed by at least one groove of the transfer needle extending in the longitudinal direction of the transfer needle.
  • a first formed on one longitudinal side groove is provided, which continues in a formed on the other longitudinal side of the second groove, which in turn continues in a formed on the first longitudinal side of the third groove, wherein the needle body between the end of the first groove and the Beginning of the second groove and between the end of the second groove and the beginning of the third groove in each case has an opening, and wherein a correspondingly formed Kastenum cognitivefeder mounted in the grooves and passed through the apertures.
  • the length of the openings determines the maximum displacement of the box suspension spring.
  • the height fixation learns the Kastenum vonfeder by the first two longitudinal grooves.
  • the lateral fixation of the Kastenum vonfeder done at its end by a bent Kastenum vonfeder Symposium Foundation, which is arranged in the third groove.
  • the movement of the Kastenum von chest between their Um von foundation and their mesh sharing position can be easily done over a foot of the Kastenum von yogafeder.
  • the foot can be moved using a knit lock.
  • a transfer needle 1 has a displaceable in the longitudinal direction of its needle body 11 box suspension spring 3 .
  • the box suspension spring 3 can be brought at least into the following positions: first in the transfer position UN and secondly in the mesh separation position MT. Furthermore, positions are still possible in which the spring breast 35 is behind the needle breast 12 .
  • Fig. 1a shows the transfer needle 1 in the view in which can be looked at a nose 31 of the box suspension spring 3.
  • the box suspension spring 3 is in a retracted position, in which its spring breast 35 is congruent with a needle breast 12 of the transfer needle 1. This is the wrap position UN when transferring a loop from the transfer needle to the transfer needle.
  • the needle breast 12, a needle neck 13, a needle hook 14 and a needle tongue 15 largely correspond to a Um contemplatadel with rigid Kastenum von yogafeder, as in the prior art.
  • the needle body 11 is along its longitudinal side, on which the nose 31 of the longitudinally displaceable Kastenum suitfeder 3 is provided with grooves 16 and 16 ' , which are designed in their width and depth so that they provide a guide for the longitudinally displaceable Kastenum cognitivefeder 3 form.
  • a groove 17 is formed, the depth of which corresponds at least to the thickness of the box suspension spring 3. Its height is slightly greater than the height of the Kastenum cognitivefeder 3.
  • a groove 19 extends into the needle neck 13. Its underside is at the same height as the bottom of the groove 16. Its height is slightly greater than the width of the nose 31.
  • the lateral fixation of the Kastenum rehabilitationfeder 3 is given by their cranked Kastenum cognitivefeder Society 34 is guided in the groove 17, and their Kastenum cognitivefeder Societye 32 and 33 in the grooves 16 and 16 'are guided.
  • the movement of the transfer needle 1 is initiated via a butt 10 .
  • the longitudinal movement of the Kastenum vonfeder 3 in the needle body 11 is initiated by her foot 36 .
  • Fig. 1b protrudes a Kröpfungsstelle 37 of Kastenum therapeuticfeder Schemes 32 through the opening 18.
  • a Kröpfungsstelle 38 protrudes through the opening 18 '.
  • Characterized the Kastenum concerningfeder Scheme 34 is located on the opposite longitudinal side of the Kastenum vone 32 and 33, whereby a lateral guidance of the Kastenum vonsky muscle 3 is realized on the needle body 11.
  • a box-shaped widening 39 of the box suspension spring 3 engages with the tip of the nose 31 in the groove 19th
  • Fig. 1c shows the transfer needle 1 accordingly Fig. 1a ).
  • the Kastenum vonfeder 3 has been moved by an application of the foot 36 in the direction of an arrow 50 from its Um yogaposition UN in their mesh separation position MT.
  • the spring breast 35 of the box covering spring 3 covers a region of the needle tongue 15 located in the reserve position and thus in the open position.
  • a stitch can not slide behind the needle tongue 15.
  • Fig. 2a) to 2f show method steps of a mesh division with a needle according to the invention.
  • the illustration is on the transfer needle 1, which is referred to as transfer needle, a participating in the stitching second transfer needle 1 'of the opposite needle bed, which is referred to as takeover needle, a dividing, carried by the transfer needle 1 mesh 6 of the knitted fabric 61 and the central axis 100 of the knitting machine reduced.
  • Fig. 2a shows a representation in which the transfer needle 1 and the take-over needle 1 'are in their basic position.
  • the stitch 6 of the knitted fabric 61 is located in the needle hook 14 of the transfer needle 1.
  • the longitudinally displaceable box suspension spring 3 'of the take-up needle 1' remains in a retracted position.
  • the longitudinally displaceable Kastenum von plausible relation 3 of the transfer needle 1 is brought in the direction of arrow 60 in its advanced mesh separation position MT. It remains in the mesh separation position MT throughout the process of meshing.
  • the transfer needle 1 is driven in the direction of an arrow 70 in its position to the mesh parts.
  • the loop 6 slides from the needle hook 14 on the opening needle tab 15 until it comes to rest against the spring breast 35 of the box suspension spring 3.
  • the mesh 6 can not slide behind the needle tongue 15.
  • the take-up needle 1 'begins a shoot-out movement in the direction of an arrow 80 into its entry position into the loop 6.
  • the transfer needle 1 ' is moved further in the direction of the arrow 80 to its final position of stitch transfer. It slides with her needle hook 14 ' in the expansion 39 of the Kastenum vonbericht 3, and thus by the widened mesh. 6
  • the transfer needle 1 is retracted in the direction of an arrow 75 .
  • the stitch 6 slides back from the needle tongue 15 in the direction of the needle hook 14 of the transfer needle.
