Definitions

  • the present invention relates to a needle arrangement for knitting machine according to the preamble of claim 1, and more particularly to a transfer needle which has an integrally formed transfer-shoulder.
  • Needle arangements of this kind are known for loop transfers from cylinder needles to dial needles (US-A-2 953 914) as well as for loop transfers from cylinder needles to adjacent cylinder needles (DE-A-3 239 111).
  • Fig. 1 to 10 illustrate the structure of a further conventional needle for the loop transfer between cylinder and dial needles.
  • the conventional cylinder needle 1 is formed below a hook 12 and a latch 13 with a fixed groove 15 which has two fixing edges 14 at each side.
  • a transfer-shoulder 11 of the needle 1 is welded to the fixed grove 15, forming an eye 16 of transfer needle thereat.
  • the transfer-shoulder 11 of the needle 1 tends to be compressed and therefore become flattened.
  • a flattened transfer-shoulder 11 of the needle 1 will cause faults in needle transfer, as illustrated in Fig. 6.
  • a yarn tangled with the needle 1 during the process of transferring will cause an upper end of the transfer-shoulder 11 to deform and tightly press against a stem of the needle 1, making the dial needle 5 be detained in the eye of transfer needle 16 of the needle 12 and causes difficulty in the transfer of the dial needle 5 and accordingly, faults in the stitch, as shown in Figs. 7. to 9.
  • Such tangled yarn and deformed eye of tansfer needle 16 result in frequent faults in the knitting, inferior quality, and increased production cost.
  • needles 1 are respectively seated in needle grooves 41 formed on a needle bed 4 and are located and separated only by every two adjacent projected needle walls 42. Since the needle bed 4 has top gaps between every two projected needle walls requiring extended space to meet the need of knitting, needles 1 unstably shake either to the left or the right during transfer. This also results in products with inferior quality.
  • a primary object of the present invention is to provide an improved needle arrangement for a knitting machine.
  • the needle arrangement according to the type above specified includes the characterizing features of claim 1.
  • each cylinder needle is formed with a hook and a latch and a transfer-shoulder being provided on a stem of the needle below the latch and forms an integral part of the needle.
  • the transfer-shoulder of the needle is so formed that it has a curved cross section and an outward and downward inclined top edge which forms a shoulder clip between the transfer-shoulder and the needle.
  • the stem of the needle and the integrally formed transfer-shoulder together form an eye of transfer needle which extends across the projected needle wall formed on the needle bed when the needle is seated on the needle bed.
  • the shoulder clip permits the yarn tangled with the cylinder needle to be easily hooked by the dial needle without causing faulty loop transfer and adversely affecting the quality of the products.
  • the present invention relates to an improved needle structure which includes a needle 2 having a hook 22, a latch 23, and a transfer-shoulder 21 integrally formed with a stem of the needle 2 below the latch 23.
  • the transfer-shoulder 21 has a downward and outward inclined upper edge from where an eye of transfer needle 24 and a shoulder clip 25 are formed. With the transfer-shoulder 21 so formed, a yarn tangled with the needle 2 can still be transferred to a dial needle 5 without faulty loop transfer.
  • the needle 2 is seated on a needle bed 3.
  • a plurality of axially extended and outwardly projected needle walls 31 are formed around a peripheral wall of the needle bed 3 so that a needle groove 32 is formed between every two adjacent projected needle walls 31.
  • the projected needle wall 31 each has a narrowed upper ridge portion 311 and an extended lower portion.
  • the needle 2 is located in the needle groove 32 with the narrowed ridge portion 311 of the needle wall 31 received in the integrally formed transfer-shoulder 21 of the needle 2, such that the needle 2 has a controlled travel, that is, to stably move up and down in a shuttling movement in the needle groove 32.
  • the problems of a deformed cylinder needle 2 preventing the dial needle 5 from hooking up the yarn as well as the products with inferior quality can therefore be avoided.
