Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for simultaneously cutting the same weft yarn at several locations on a knitted fabric side on an automatic knitting machine, and to a weft placement.

The method and device of the invention also makes it possible to obtain two or more knitted fabric zones H, which can be collected respectively by means of a bobbin Kg taking button, [1@h knitting vy] with successive buttons and at the same time. . To be more specific, the present invention is a weft insertion type eye! lF! This invention relates to a method, τ, and an apparatus for simultaneously cutting the weft threads of a knitted fabric at several locations on a knitting machine.

It is absolutely necessary to cut the same weft thread on the knitted fabric side at the same time for all the points selected for cutting. This is a skillful sweep. In fact, the weft threads on the knitted fabric side must be under tension at the moment of cutting, and if this - at the moment when the cutting occurs in the tube place, the cutting should occur at the same moment in all the selected Ml places. For example, it is practically impossible to make a stop cut at another selected point, since the weft thread is no longer under tension.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a method and a device capable of simultaneously cutting the same weft yarn at several locations on the knitted fabric side on an automatic knitting machine.

Another object of the present invention is to provide a method and a device that can simultaneously cut the weft threads on the knitted fabric side of an automatic knitting machine at several locations, ensuring that the lengths of the cut weft thread segments are exactly equal. .

Yet another object of the invention is that the weft threads] 1 - in the form of hollow fibers;
In particular, when the hollow fiber form is used in the field of artificial kidneys, the method and apparatus are particularly well suited for cutting all the weft threads on the knitted fabric side. The hollow fibers may be made of cellulose material, for example.

Another object of the present invention is that the yarn used to form the IFmth around the weft yarn has a hollow region Sj (e.g. heated multiple yarn,
A well-suited method and equipment for cutting the weft threads in the form of hollow fibers at several points on the knitted fabric side when the non-hollow threads are in the form of I# with a diameter smaller than the outer diameter of the thread. It is to provide.

It has now been discovered that the object and power of the present invention is to
Immediately after the stitches of each warp thread are tightened around the weft threads, K during the formation of the stitches on the next thread.

This is a device for simultaneously cutting the same weft on the knitted fabric side of an automatic knitting machine at several locations, characterized by having three or more cutting elements (1N) for cutting the weft at desired locations.

Similarly, the object of the present invention is to create a J5.1 yarn of 47+1 yarn after each stitch of the yarn is formed, and while a stitch is formed at the desired location of the next +, +4 yarn. This is a method of simultaneously cutting the same weft yarn on the knitted fabric side of the automatic die cut frame in several places, which is characterized by cutting the +7/- system at several places at the same time.

The description of the method and apparatus of the present invention will be better understood with reference to the accompanying drawings, which schematically illustrate one embodiment of the invention, although the present invention is not limited to this embodiment.

The figure below further shows 1t, weight, lr, IBA, C
0PCEN-TRA A type of +? known worldwide as H8? The method and apparatus of the present invention are particularly advantageously implemented in a 1'1 thread-in type automatic knitting machine.

FIG. 1 is a schematic diagram showing in detail the basic knitting elements for forming the knitted fabric side on an automatic knitting machine as described above.

FIG. 2 is a schematic perspective view showing in more detail the relative positions of the elements and the position of the cutting element of the invention.

Figures 3 to 5 schematically show how the cut ammonium of the present invention moves when forming a stitch around a weft thread.

FIG. 1 shows the main elements that apply Vcp to form a stitch around the weft of a LIBA COPCENTRA H8 type automatic knitting machine. In particular, the guide needle support 'pP1 to which the guide needle 2 (the hook of the crease) that forms the % stitches is fixed.
, the support rod 3 of the sinker to which the needle 4 is fixed, the support frame 5 of the sliding groove to which the sliding groove 6 is fixed, the support rods 7 and U of the sinker to which the sinker 8 (picking plate) is fixed, ″j
The support rod 9 of the insertion plate, to which the thread insertion plate 10 is fixed, is particularly appreciated.

The weft thread 11 is an endless bell (k) that holds the thread with a hook.
Following the band forming the stitch, there is one belt at each end of the weft thread. In FIG. 1, the 1FBj yarns 11 are, for example, hollow fibers, but to simplify the explanation, they will all be called weft yarns 11 in the same way. The weft yarn 11 is supported by a belt (not shown) and advances to the left from the upper cloth in FIG. It is especially suitable for making fabrics intelligently.

In fact, such a [1 motion 111) milling machine has a thread 11 at 4'1°, for example, a commercial name CU yen (OPI (AN's ladle 111), and a hollow 0 shi fiber (inner diameter α2 , wall thickness 0.

, 70. If you use polygostyl mesh thread 12 of 1 piece (p), you can make an artificial kidney with a hollow wire J (
It is convenient to use a silk fabric that can be made into 4 bundles. For example, it is possible to make stitches every 2-3 α with the warp 12 over the entire length of the weft 11 (about 3.2 m in length). In this case, the distance between the threads 12 is 2-5-
Tracing the inside of the guide needle 2. On the other hand, at the point where it is intended to cut the cotton yarn 11 around which the stitches are tightened, that is, at the point where the obtained knitted fabric is intended to be cut, the cutting of the obtained knitted fabric is carried out, as will be well understood in the following hooking method. It is advantageous to place some of the stitches closer together (e.g. 1-2 CFI+ spacing) so that the ends are tighter. In this case, the guide needle 2 is provided closer to those locations.

Unknown+11ti In 91, the term "knitted fabric" generally refers to mutually parallel (hollow)), 7
This term refers to all products consisting of yarn 11 and vertical warp yarns 12, in which the warp yarns 12 form entire stitches around the weft yarns 11 (including mats, knitted fabrics, etc.) .

The various knitting elements 1 to 10 that serve to form a stitch around the weft thread 110 are the cutting elements 13 at the base ξ position according to the invention.
The insertion plate 111 of the weft thread 11, the sinker 8 and the needle 4 are all spaced apart from each other, and during their respective movements the well-known luck! (There is no contact.

The sliding groove 6, referred to by those skilled in the art as a ligule, is the only one in contact with the needle 4. The cutting intersection 13 is similarly spaced apart from the other elements mentioned above.

In the device according to the invention, the cutting element 13 is fixed to the support rod 3 of the sword 4, for example at the points where the needle 4 is raised, and the sliding groove 6 is likewise held at these points. For this reason, an amputee with a total of 13, for example a cutter, has a sinker of 8
and the insertion plate 1o. FIG. 2 shows in a perspective view how the cutter 16 passes through the bar of the sinker 8 in the same way as the needle 4 with the hook 15.

Figures 3 to 5 are shown in 1.4. When a stitch is formed around H5 yarn 11, the present invention's 4%'l', -near (

FIG. 5 shows that (the thread 11 formed in each of the desired decorative bars r is threaded through the back 17 of the sinker 8 in the groove 14 of the sinker 8, Each sinker 8 is at its rightmost end and begins to move to the left, ie forward.

Each insertion plate 10 reaches its highest and previous position, that is, the leftmost position in the drawing. The weft thread 11 around which a new stitch has begun to form (at a desired location) is also trapped between the thread 12 passing through the guide needle 2 and the insertion plate 100. The needle 4 reaches the lowest position and its hook 15 is closed by the sliding ratchet 6. Each side 5 includes 3 loops of warp threads 12. Cutting, the J731 element 13 is concave with the needle 4, and the lower part of the passage 5 is also located at 'l'. The guide needle 2 begins to move backwards beyond the downward direction and toward the direction of the drawing.

It would be advantageous to provide a thread.In fact, when cutting at both ends, the thread is held again by the hook of the svelte and can be removed by the tensioner. The entire length of the weft is actually examined:
In order to make a J-shape, therefore, on each side of the automatic knitting machine, between each outer sheath 16 and the nearest endless belt (f),
It is advantageous to provide a device for making it linear, i.e. contained in the groove 14 of the sinker 8, over the extension of the same weft thread. In order to do this, place a firm and smooth metal wire mantle that can simultaneously fix the upper position on the horizontal plane and the vertical W1 plane with respect to the earth. 5- is provided with a loop-like device and is removed with a dot/tweet. Of course, it is done by aiguchi; qυ.

Other variations of method 4.5 and device 4 above are also within the scope of the invention. In contrast to cutting the weft yarn which has just been tightened and has a number of stitches formed around it at its entire length, it is also possible to cut the weft yarn at the bottom of the entire length of the weft yarn, and to cut the weft yarn at the staking point of the next camellia yarn. It can be said that the cutting element for cutting the tip is placed within 1 radius of the trunk.
The supporting rod 3 (fixing and cutting the weft thread during the upward movement of the needle P) is also considered to be pronation according to the invention.
