DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slider-type knitting needle for a knitting machine, a so-called composite needle, and more particularly to a needle having a beard and a slider having a bat, a nose and a stitch holding shoulder, and the nose of the slider. The present invention relates to a slider-type knitting needle for a knitting machine in which a slider is movable with respect to a needle so as to open and close a beard and to move a stitch by moving a stitch by a nose and a shoulder portion of the slider.

[0002]

2. Description of the Related Art Knitting needles of the slider or piston type have long been known.

[0003] The first slider-type knitting needle used industrially was developed in 1924 by J.F.
F. WILCOMB) and has a needle that is moved within the slider. This structure only closed the needle beard, and the stitch could not be transferred by the slider.

US Pat. Nos. 4,043,153 and 5,186,026 and German Patent Application Nos. 3,151,150 and 3,220.
Nos. 049 and 4231 015 disclose slider-type needles, the actual needles being in the form of a slider, in which a piston is moved, the piston being a needle. Up his beard. The use of a piston to close the needle whiskers makes it possible to eliminate the conventional needle spatula, thereby obtaining a more robust needle and reducing the stroke of the needle when a stitch is formed. I do. Further, the piston allows for stitch transfer from one section needle to the opposite section needle. The structure with a piston and a needle in the form of a slider has also been adopted by other manufacturers. The needle is always below the piston except in the construction of U.S. Pat. No. 4,434,627, in which the piston is U-shaped and located below the needle. doing.

[0005] In order to effect stitch transfer, slider-type needles sometimes have an additional part which is fastened to one side of the needle (see DE 36 24 038).

[0006] Composite needles with lateral springs and needles with double sliders are also known.

Generally, in prior art piston-type knitting needles, the transferred stitch is always received by the needle whiskers and received therein. Thus, if the stitches are already in the whiskers of the needle, it is difficult to distinguish subsequent stitch transfer or knitting steps for each of these stitches.

On the other hand, it is necessary to use an auxiliary section for the operation of transferring a set of stitches from a certain number of needles to a laterally adjacent needle, usually called "punching". In its auxiliary section, the needle or punch picks up the needle stitches and transfers them to other needles.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to create a slider-type knitting needle which offers new knitting possibilities, and in particular enables punching without the need for auxiliary sections or punches. It is to be.

[0010]

According to the present invention, there is provided a knitting needle of a slider type according to the present invention, wherein the slider has a U-shaped shape, and the slider straddles the needle, whereby the slider has an end region forming the nose. And allow the opposite needle or slider to pass to perform stitch transfer or punching.

In a flat knitting machine having two longitudinally movable sections, the slider-type knitting needle according to the invention not only performs the known stitch transfer function, but also
It is also possible to perform a punching function on the needle of the opposite section as a result of the movement of one section. Thus, the auxiliary sections and their punches can be eliminated.

[0012] Because the slider straddles the needle, the needle can be retracted into the slider with one or more stitches, while the other stitches rest on the slider located higher. it can. The stitches on the slider are then transferred to the slider or to the same section needle beard or to the opposite section needle. Thus, the stitches can be separated by one and the same needle and act on them in different ways.

[0013] In order not to damage the stitches located in the slider in this way, the slider has, in a part of its length, an inner width substantially larger than the thickness of the needle, starting from its nose. Have a stitch that is located within the whiskers of the needles.

The movement required for the various operations of the slider-type knitting needle according to the invention is of very low amplitude. This reduces the length of the cam holder, reduces the travel of the carriage and increases the productivity of the knit.

In summary, the slider-type knitting needle according to the invention makes it possible to: a) receive stitches on a slider with one or more stitches in the whiskers of the needle corresponding to the receiving slider. B) receiving stitches on the needle stitch, c) transferring this stitch or other stitches while holding one or more stitches in the needle beard corresponding to the slider to be transferred The stitches on the needle whiskers are subsequently moved or knitted; d) the slider can be used as a relay element for moving one stitch or a set of stitches of the same section by punching. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. The accompanying drawings show an example of a slider-type knitting needle according to the present invention as an example. FIG. 1 is a side view at a knitting position, FIG. 2 is a side view of only a slider, and FIG. 5 is a top view of the slider as viewed in the direction of the arrow, and FIG. 4 is a cross-sectional view as viewed in the IV-IV direction of FIG.
6 shows a slider-type knitting needle in a stitch transfer preparation position, FIG. 6 shows a slider-type knitting needle in a stitch transfer position, and FIG. 7 shows a slider-type knitting needle in a position punched by a needle slider in an opposite section. Is shown.

The knitting needle of the slider type shown comprises a needle 1 and a slider 2, and the inside of the slider 2 is
Moves. The needle 1 has a beard 3 at one end. In the illustrated embodiment, it is assumed that this needle is driven by a key, so that needle 1 does not have a bat. However, the needle can also include one or more bats so that the needle is driven by the cam of the cam holder. The slider 2 has a U-shape (FIG. 4)
The slider 2 has a needle 1 due to this shape.
Straddling. At the rear, the slider 2 has a butt 4 for driving the slider 2 and at the front, the slider 2 has a nose 5, the upper part of the nose 5 being located below the level at the back of the slider. To form a shoulder 6. Above the nose 5, both sides of the slider 2 are closed again along the connecting line 15, thereby forming a round sliding surface for the stitch. Furthermore, the ends of these two side surfaces are connected to the end surface of the nose 5 and the slider 2.
Are rounded off with the lower end portions 8. Behind the shoulder 6, the U-shaped profile is interrupted for a certain length, forming a passage 7 on the back of the slider. Starting at its nose 5 over part of the length of the slider, the average width of the U-shaped shape of the slider is substantially greater than the thickness of the needle 1. 1, 5, 6 and 7 schematically show the profile of two opposing sections 9 and 10 of a flat knitting machine with two sections.

In FIG. 1, the beard 3 of the needle 1 is closed by the nose 5 of the slider so that the thread 11 is captured by the beard of the needle.

FIG. 5 shows a state in which the slider-type knitting needle is at a preparation position for stitch transfer. Needle 1 is at a high position. By sliding over the needle, the thread 12 is lifted above the nose 5 of the slider.

In FIG. 6, the needle 1 is shown in a state in which the needle 1 is turned down. The slider 2 is lifted and the stitch rests on the shoulder 6 of the slider. Opposite section 1
0 needle 1 'can engage slider 2 and slide 2
Through the slider 2 through the passage 7
Pick up the stitch held in the stitch and transfer the stitch. In this position, it can be seen that the beard 3 of the needle 1 is within the U-shaped part of the slider. The play between the needle 1 and the slider 2 allows the stitches located at the whiskers of the needle to engage in the slider without damage.

FIG. 7 shows a slider-type knitting needle in the same position as in FIG. 6, but instead of the opposite needle 1 'engaging with the slider 2, a corresponding slider 2' Is engaged. When the slider 2 is turned over, the stitch at the nose of the slider 2 is positioned on the slider 2 '. Here, therefore, the function of the slider 2 'is that of a punch. Section 10
Can be moved to the left or right so that the stitches held in the slider 2 'can be moved onto the needle 1' of the section 9 or the slider 2
It is possible to transfer on. All possibilities are provided in this way.

It is highly preferred that a plugged hole technique is possible and that a comb transfer is also possible with this slider, as described in EP 0 362 126.
