Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to stockinette knitting needles, particularly knitting needles for stitch transfer in stockinette knitting.

[Conventional technology]

Generally, in stockinette knitting work, when knitting a stockinette with an odd knit, the knitting needle automatically transfers the loop held by the knitting needle to the adjacent knitting needle, but a knitting needle that has this stitch transfer function A special knitting needle uses a flat plate for the stem to form a stepped loop shoulder, and below the loop shoulder, the side of the stem is curved, or bulged, to form a concave part that continues to the lower edge. , one is known in which it is easy to accept adjacent feeding needles (Japanese Patent Application Laid-open No. 78855/1983).

[Problem that the invention attempts to solve]

Conventional transfer needles use a flat plate, so the hook formed at the tip must be wire-drawn into a circular cross section and bent into a hook shape, which is not only difficult but also requires swaging. It is not possible to do this, making the processing cost relatively high, which is not good in terms of quality control.Furthermore, it is slender and weak in strength, and has a short lifespan.In addition, high-speed needle movement causes problems such as high wear and tear and a high tendency to break. .

Also, when transferring stitches, a step is provided to lock the loop, but this step alone will cause the loop to slip easily, and if this loop is not held properly, the loop will move all the way to the back and be transferred. The knitting needle could not penetrate into the loop, and there was a risk that efficiency would further decrease as the speed increased.

The present invention accurately eliminates these conventional drawbacks,
The object of the present invention is to provide a stockinette knitting needle for stitch transfer at a low cost, which allows stitch transfer work to be carried out efficiently and stably by maintaining the loop in an optimum state for transfer.

[Means for solving the problem] The present invention forms a hook 2 at the front end of the needle stem 1,
It is provided with a latch 3 for opening and closing the hook 2, and a butt 4 on the opposite side of the hook, and a stepped portion 5 for loop engagement on the upper surface of the needle stem behind the pivot point of the latch 3. In a transfer needle that is provided with an elastic piece 6 that can perform a stitch transfer operation on the side surface, spanning at least the side part of the step part 5, at a corner of the step part 5, the side surface of the needle stem on which the elastic piece 6 is provided is A thread retaining groove 7 for hooking a loop is formed on the opposite side with a smooth curve, and the elastic piece 6
This stockinette knitting needle is characterized in that a stepped portion 6' is formed along the upper edge of the stepped portion 5.

[Effect]

With this transfer stockinette knitting needle, when transferring a loop held by one knitting needle to an adjacent knitting needle during stockinette knitting, the loop held is expanded while sliding on the elastic piece 6 for loop expansion. It is inserted into the latching thread holder groove 7 in the part 5 and is prevented from slipping. Next, the tip of the knitting needle to which the loop is to be transferred enters the knitting needle entry gap in a state where it passes through the loop, and then the knitting needle to which the loop is to be transferred moves to the retracting process, and the loop is held in the thread holder concave groove 7 at the advanced position. The loop passes between the tip of the knitting needle to be transferred and the hook by the elasticity of the elastic piece 6, and when the loop comes off the knitting needle to be transferred, the knitting needle to be transferred moves to the backward process, and the loop is completely completed. It will be held only on the knitting needle that is transferred to the knitting needle. In this case, the loop is formed between the elastic piece 6 and the step 5.
Since the loop is held securely by the thread retaining groove 7 provided in the section, the position of the loop is extremely accurate, and even at high speeds, the hook of the knitting needle being transferred remains accurately within the loop without moving backwards. Since it enters into
This allows stable operation to continue.

〔Example〕

Embodiments of the present invention will be described based on examples in FIGS. 1 to 4.

A hook 2, a latch 3, a butt 4, a step 5 for locking the loop, and an elastic piece 6 for expanding the loop.A thread holder for hooking a loop is provided on the side surface at the base edge of the step 5 of the needle stem 1. Concave grooves 7 are formed to constitute transfer stockinette knitting needles. In this case, the thread retainer groove 7 is a hollowed-out recess having an arcuate surface that is on the side opposite to the side where the elastic piece 6 is provided and that is continuous with the vertical corner (edge) straight line of the stepped portion 5. It is formed as a thread holder, and in any case, it is formed by passing the side edge of the front upper surface of the stepped portion 5 of the needle stem 1, and is formed with a smooth curved surface.

The elastic piece 6 is made of a spring plate material such as a tapered plate spring, and at least one end of the elastic piece 6 is fitted and locked into a mounting groove 8 formed on the side surface of the needle stem, so that the needle is positioned so that the stepped part 5 is located in the center. It is provided on the stem 1 and is curved convexly in the side direction of the needle stem to form an entry gap for the knitting needles into which the stitches are transferred. Furthermore, the tip of this elastic piece 6 is a free end, extends toward the hook 2, and is fitted into the side groove 9 of the needle stem 1, so that the formation of the loop expansion portion by the elastic piece 6 can be properly maintained. There is. Furthermore, one end of the elastic piece 6, which becomes the base, is fixed by fitting into the mounting groove 8 and crushing at least a portion of the groove wall so as not to protrude from the side surface, but it may also be fixed by pivoting or other welding means. can. The elastic piece 6 is provided with a step 6' along the step 5.

In addition to the loop expansion function, this elastic piece 6 can also cushion the impact as the knitting machine increases in speed, reducing the impact on the knitting needles and reducing breakage and wear, as well as reinforcing the parts of the knitting needles that are subject to high wear and tear. It also has the effect of significantly extending the lifespan. The thread retainer groove 7 is provided at the corner of the stepped portion 5 so as to straddle both vertical and horizontal edges, as shown in FIGS. 5 and 6.
In addition, when the needle stem 1 retreats, it is best to continue with a gentle curved surface so that it does not follow the retreat, that is, it exits from above the needle stem 1 (relatively) smoothly, and sharp lines and points are avoided. Care has been taken to prevent this from occurring, eliminating the risk of the knitting yarn being damaged.

[Effect of idea]

In the present invention, in a transfer needle, a thread retaining groove for catching a loop is formed at a corner of the stepped portion, the groove being smoothly curved on the side opposite to the side of the needle stem where the elastic piece is provided. At the same time, by forming the step part along the upper edge of the step part in the elastic piece, the size and position of the loop can be made more preferable when transferring the loop, and the position of the loop can be made more preferable. Because it can be held accurately, it is possible to efficiently knit beautiful fabrics, and its movement is extremely good at high speeds, so it does not damage the knitted fabrics, and it is possible to knit products with high added value, thereby reducing efficiency and product loss. It has practical effects such as being useful for quality control and improving productivity as it can provide durable stockinette knitting needles.
