Definitions
- the present invention relates to a needle arrangement for knitting machine, and more particularly to a transfer needle which has an integrally formed transfer-shoulder.
- Figs. 1 to 10 illustrate the structure of a conventional needle.
- 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 groove 15, forming an eye 16 of transfer needle thereat.
- the dial needle 5 When a loop formed by the cylinder needle 1 is transferred toward a dial needle 5, as shown in Fig. 3, the dial needle 5 must extend through a central portion of the loop and the eye 16 of transfer needle to pass through a shoulder clip 17 on the needle 1.
- the cylinder needle 1 When the cylinder needle 1 is lowered, it causes the loop to be transferred to the dial needle 5 and be hooked by the dial needle 5.

- 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 1 and causes difficulty in the transfer of the dial needle 5 and accordingly, faults in the stitch, as shown in Figs. 7 to 9.
- 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 knitting machine.
- the improved needle arrangement according to the present invention includes a cylinder needle which works with a corresponding dial needle to form loops, a needle bed, and a plurality of projected needle walls formed on the needle bed.
- the cylinder needle each is formed with a hook and a latch.
- a transfer-shoulder is 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.

Abstract
Description
- The present invention relates to a needle arrangement for knitting machine, and more particularly to a transfer needle which has an integrally formed transfer-shoulder.
- Figs. 1 to 10 illustrate the structure of a conventional needle. As shown in the drawings, the
conventional cylinder needle 1 is formed below ahook 12 and alatch 13 with afixed groove 15 which has twofixing edges 14 at each side. A transfer-shoulder 11 of theneedle 1 is welded to the fixedgroove 15, forming aneye 16 of transfer needle thereat. When a loop formed by thecylinder needle 1 is transferred toward adial needle 5, as shown in Fig. 3, thedial needle 5 must extend through a central portion of the loop and theeye 16 of transfer needle to pass through ashoulder clip 17 on theneedle 1. When thecylinder needle 1 is lowered, it causes the loop to be transferred to thedial needle 5 and be hooked by thedial needle 5. In the case the loop density is high and it is not easy for thedial needle 5 to extend through the center of the loops, the transfer-shoulder 11 of theneedle 1 tends to be compressed and therefore become flattened. A flattened transfer-shoulder 11 of theneedle 1 will cause faults in needle transfer, as illustrated in Fig. 6. Moreover, a yarn tangled with theneedle 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 theneedle 1, making thedial needle 5 be detained in the eye oftransfer needle 16 of theneedle 1 and causes difficulty in the transfer of thedial needle 5 and accordingly, faults in the stitch, as shown in Figs. 7 to 9. Such tangled yarn and deformed eye oftransfer needle 16 result in frequent faults in the knitting, inferior quality, and increased production cost. Further,needles 1 are respectively seated inneedle grooves 41 formed on aneedle bed 4 and are located and separated only by every two adjacent projectedneedle walls 42. Since theneedle 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. - It is therefore tried by the inventor to develop an improved needle arrangement to eliminate the above mentioned drawbacks existed in the conventional needle.
- A primary object of the present invention is to provide an improved needle arrangement for knitting machine. The improved needle arrangement according to the present invention includes a cylinder needle which works with a corresponding dial needle to form loops, a needle bed, and a plurality of projected needle walls formed on the needle bed. The cylinder needle each is formed with a hook and a latch. A transfer-shoulder is 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.
- With the arrangements provided by the present invention, 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 can be better understood by referring to the following detailed description of the preferred embodiment and the accompanying drawings, wherein
- Fig. 1 is a front elevational view of a conventional needle;
- Fig. 2 is a side elevational view of the conventional needle shown in Fig. 1;
- Fig. 3 illustrates the manner in which the conventional needle cooperates with a dial needle to transfer and knit loops;
- Figs. 4 and 5 illustrate the process of knitting by the conventional cylinder needle and dial needle;
- Fig. 6 illustrates a compressed and flattened transfer-shoulder which prevents a loop from transferring to the dial needle;
- Figs. 7 to 9 are side elevational views of Figs. 3 to 5, respectively;
- Fig. 10 is a front elevational view showing the needle bed for the conventional needles;
- Fig. 11 is a fragmentary front elevational view of a needle according to the present invention;
- Fig. 12 is a side elevational view of Fig. 11;
- Figs. 13 and 15 illustrate the knitting process by the needles according to the present invention;
- Fig. 14 is a fragmentary and enlarged view of Fig. 13;
- Fig. 16 is a schematic view showing the needle bed according to the present invention;
- Fig. 17 is a fragmentary and enlarged perspective view of Fig. 16;
- Figs. 18 and 19 show the unstable transfer of the conventional needles from the needle bed, as well as knitting carried out by the unstable needles with offset gating; and
- Fig. 20 and 21 show the stable transfer of the needles of the present invention from the needle bed, as well as knitting carried out by these stable needles with centralized gating.
- Please refer to Figs. 11 through 15. The present invention relates to an improved needle structure which includes a
needle 2 having a hook, 22, alatch 23, and a transfer-shoulder 21 integrally formed with a stem of theneedle 2 below thelatch 23. The transfer-shoulder 21 has a downward and outward inclined upper edge from where an eye oftransfer needle 24 and ashoulder clip 25 are formed. With the transfer-shoulder 21 so formed, a yarn tangled with theneedle 2 can still be transferred to adial needle 5 without faulty loop transfer. - Please further refer to Figs. 16 through 21. The
needle 2 is seated on a needle bed 3. A plurality of axially extended and outward projectedneedle walls 31 are formed around a peripheral wall of the needle bed 3 so that aneedle groove 32 is formed between every two adjacent projectedneedle walls 31. The projectedneedle wall 31 each has a narrowedupper ridge portion 311 and an extended lower portion. Theneedle 2 is located in theneedle groove 32 with the narrowedridge portion 311 of theneedle wall 31 received in the integrally formed transfer-shoulder 21 of theneedle 2, such that theneedle 2 has a controlled travel, that is, to stably move up and down in a shuttling movement in theneedle groove 32. The problems of a deformedcylinder needle 2 preventing thedial needle 5 from hooking up the yarn as well as the products with inferior quality can therefore be avoided.
