Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for producing a patterned pile knitted fabric on a warp knitting machine.

For example, in order to produce patterned knitted fabrics, it is known that all non-pattern-forming pile yarns are placed under the needles in alternating directions and are thus knitted as supporting weft yarns between the needle looses and sinker loops of the stitch row. It is.

The pile yarns forming the pattern are then selected by the yarn selector via the pattern device and placed in selected or unselected positions below the needles by means of additional means attached equally to all needles.

The selected pile yarn is once knitted between the needle loop and sinker loop of an adjacent stitch row by the pile sinker, and is knitted in the next stitch row in the same manner as the first stitch row.

However, in this method, the pile yarns forming the pattern are woven by the warp yarns only once in each stitch row,
There is a drawback that the knitting position is located on the pile side of the product.

In such a situation, the rubber layer covering the back side of the product will not be located at the knitting points, so that if the pile yarn or the entire pile loop is cut, these pile loops will be pulled out.

Such carpets are particularly susceptible to damage from mechanical stress during the first few months of use.

In order to eliminate this drawback, a method is already known in which the pile yarns are captured by needles and formed into stitches on the back side of the product, either by the pile yarns alone or together with the pile yarns and the warp yarns.

However, it is difficult to implement this method in the production of jacquard patterned knitted fabrics.

This is because in this case, the pile yarns that do not form a pattern also form stitches.

This requires a very large amount of pile yarn, and the development and production of knitted fabrics using the jacquard method has traditionally not been efficient.

It is an object of the present invention to avoid such large pile yarn requirements.

According to the invention, the pile yarns belonging to the first stitch row alternate in each subsequent stitch row in a manner known per se.
Each pile yarn in the first stitch row is knitted between the needle loop and the sinker mesh of the stitch row, and each pile yarn in the first stitch row is knitted as a stitch in the adjacent stitch row, and This is also done by knitting as a stitch in the stitch row.

The apparatus for carrying out this method is such that the double pile yarn guide is moved from a first position between a first needle and a second needle to a second position by approximately two needle sections, and A yarn selector located in the yarn selector is movable forward between the double pile yarn guide and the third needle together with its yarn guide groove to a position where only the third needle can knit the selected yarn. It is configured like this.

Preferably, the leading opening of the double pile thread guide is arranged approximately parallel to the longitudinal axis of the needle, above the needle front in the raised position, and the thread selector is arranged from a position above the pile thread guide. It descends to the needle amount position.

The thread selector is controllable from one leading shedding to another according to a pattern.

The double pile guide member is moved much closer in the first position than in the second position.

In order that products knitted with pile threads as weft threads, as is known, can also be produced selectively with the device of the invention, the double pile thread guide is arranged in a first position before or during the needle ascent. and the thread selector is also lowered to the bottom of the needle in the second position before the needle is raised.

Embodiments of the present invention will be described below with reference to the drawings.

The device for carrying out the method of the present invention comprises horizontally movable needles L2, 3, 4, the needle heads of these needles 1, 2, 3, 4 are fixed by a pressing member 5. There is.

The needles 1 to 4 are guided in a knockover cam 6 and supported by pile sinkers 8 fixedly attached to a fixed bar 7.

A double pile yarn guide 9 is supported by a bar 10 so as to be located immediately in front of the pile sinker 8.

The bar 10 is movable in the longitudinal and transverse directions of the needle rows and also in the vertical direction of the needle rows.The lambda double pile yarn guide 9 is bent forward.

A plurality of thread holes 11 are arranged in a horizontal plane in the horizontal portion of the double pile thread guide 9.

A vertically movable yarn selector 13 is provided above the double pile yarn guide 9.

This thread selector 13 is positioned to match one of the plurality of thread holes 11 in accordance with the pattern of the knitted fabric, and
In the upper position, it is located above the double pile yarn guide 9.

A weft thread arrangement device 14 is arranged behind the pile sinker 8 and above the needles 1 to 4.

This weft thread placement device 14 moves over at least three needles and performs a vertical movement while the needles 1 to 4 reach the knockover position and are located below the weft thread.

Further, a warp thread arrangement device 16 is arranged coaxially with the needles 1 to 4 and in front of the needles.

This warp arrangement device 16 performs the arrangement of the tassels.

The article produced by this apparatus is shown in FIG.

The knitted fabric base is formed by weft threads 15, the number of weft threads being the same as the number of needles.

These weft threads are connected to four needles in each stitch row.
will be inserted below.

Therefore, it is knitted in the stitch row of the warp yarn 17 between the needle loop and the sinker loose.

In the above example, three pile yarns 18, 19, 20 are arranged for each stitch row.

In this case, the pile yarn that does not form a pattern is knitted in the stitch row 21 as a so-called support weft yarn.

That is, these pile yarns are woven with their respective needles 2 in alternating directions from stitch row to stitch row, thereby being knitted between the needle loops and sinker loops of the warp yarns 17.

Each pattern pile yarn M is guided to an adjacent needle 3 in the first stitch row, is gripped by the hook of this needle 3, and forms a stitch together with the warp yarn 17 of this stitch row 22.

Since the pile sinker 8 exists between the two needles 2 and 3, the pile yarn M forms a pile loop.

In the next stitch row, the pattern pile yarn 19M is again knitted into its own stitch row 21.

However, since this pile yarn occupies another position by being knitted into the adjacent stitch row 22 as a stitch, in this case it is again passed through the needle head by the pile sinker 8 to form a stitch.

The non-patterned pile yarns 18, 20 are arranged below the needles in the direction from left to right in FIG.

In addition, in the action explanatory diagrams shown in FIGS. 2 to 7,
In the range of four needles 1 to 4, only the double pile yarn guide 9 and the yarn selector 13 are shown for ease of understanding.

The mode of operation of the weft thread placement device 14 and the warp thread placement device 16 is likewise only shown.

This is because they are generally known to those skilled in the art.

Next, the effect will be explained.

The hands are numbered 1-4 from the right.

In the starting position, the double pile thread guide 9 is above the needle shank and between needles 1 and 2.

All the pile threads 18, 19, 20 extend from behind the needles 2 to the double pile thread guide 9.

The yarn selector 13 is connected to the double pile yarn guide 9 in the ready position.
It is located between needles 3 and 4 above the horizontal part of .

That is, the yarn selector 13 has already selected the yarn hole 1 of the desired patterned pile yarn 19M by the jacquard device (not shown).
It is adjusted so that it is within the plane of 1.

To begin pushing out the needle in the first working cycle, the double pile thread guide 9 is moved to the left so that the thread selector 13 can be lowered downwardly between this double pile thread guide and the needle 3 (third (Fig. and Fig. 8).

The unpatterned pile threads 18, 20 extend freely from the rear side of the needles 2 past the needles 3 into the respective thread holes 11 provided in the double pile thread guide 9.

Next, the yarn selector 13 descends, and the pile yarn 1
9M is held in place, and this pile yarn 19M is pressed against the shaft of the needle 3.

Almost simultaneously, the warp threads 17 are moved to the warp thread arrangement device 16.
inserted by a rocking motion.

In the subsequent stitch escape movement of the needle 3, the needle 3 grips the warp yarn 17 and the pile yarn 18M with its needle head and forms both of them into a stitch.

When the first working cycle is completed, the weft thread placement device 16 inserts the weft thread 15 over the stitches and under the needles 1-4, and when these needles 1-4 are raised, a second working cycle begins.

The thread selector 13 has already been raised again to its starting position and is preparing a new selection via the Jacquard device.

The double pile thread guide 9 is returned to its starting position between the needles 1 and 20 again.

The pile threads 18, 20 again extend from behind the needle 2 past the lower edge of the double pile thread guide 9 into the respective thread holes 11 (FIGS. 10 and 11).

On the other hand, for pile type 19M, pile sinker 8 is inserted from the back side of needle 3.
and extends beyond the needle 2 towards the underside of the double pile thread guide 9 and into the respective thread hole 11 (shown in dotted lines in FIG. 10).

At this time, the needle 2, which is moving forward, moves between the pile yarn 19M and the pile yarns 18 and 19 to the raised position, where the double pile yarn guide 9 allows the pile yarn 19M to reach the hook of the needle 2, and the warp yarn is threaded by this needle 2. 17 until a stitch is formed.

After the stitch escape, the process starts from the beginning, in which case the yarn selector 13 selects the three pile yarns 18, 19, 20.
can be arranged according to a desired pattern.

After this operation, the pile yarn M always forms two pile loops, the front and back, so that approximately square pattern points are produced according to the spacing and thickness of the pile material.

When cutting the pile, a cutting device is attached to the pile plate extending downward.

With the device described above, the pile yarn M can be knitted during insertion of the weft yarn according to known methods.

However, in this case, it is necessary that the thread selector 13 has already been pushed down to the bottom of the needle 3 during the rise of the needle 1, and in the next stitch row, the double pile thread guide 9 must also be pressed down before the rise of the needle. It must be pushed down below the needle.

The above device forms pile gaps according to a pattern by not inserting a single pile thread, and the remaining piles can be knitted in various colors or material types.

Interesting pattern effects can also be obtained by varying the material strength and type of pile material.

As described above, according to the present invention, by knitting the pile loops as a mesh with the rubber coating layer on the back side of the product, even when human silk yarn is used as the pile material, almost perfect pile can be achieved. Fixation takes place.

The method of the present invention provides a viable method for producing shirt card pile products on a much more efficient warp knitting machine, while at the same time obtaining the additional advantages of a greater maximum pile height and the use of human silk threads. shown for the first time.
