DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on preferred embodiments with reference to the drawings.

The knitting area 1 of the warp knitting machine shown in FIG. 1 has a series of knitting needles 2 on a knitting needle bar 3. The ground yarn 4 supplied at full gauge is supplied via a ground yarn guide needle 5 attached to a ground guide bar 6. The ground guide bar 6 can be reciprocated with a tricot knit structure, for example. However, when the ground guide bar 6 knits a chain stitch, it is preferable to use a pattern yarn 7 described below to generate a continuous base cloth. The pattern thread 7 is supplied via pattern thread guide needles 8 arranged in four displacement operation rows 9, 10, 11, 12 every ご と gauge, and the displacement operation rows are held by the support 13. The pattern yarn guide needle 8 is arranged in a full gauge on the pattern guide bar system 14 thus obtained. This system undergoes a common elementary displacement movement, for example, under three knitting needles 2 (FIG. 6) or two knitting needles 2 (FIG. 7). It is the basic displacement applying device 15 that provides the basic displacement operation, and the jacquard control device 16 provides the displacement to the pattern thread guide needle 8.

The arrangement of the guide needle 8 in FIG. 1 is shown in an enlarged manner in FIG. The ground yarn guide needle 5 is composed of knitting needles 2 and 4
And the pattern thread guide needles 8 arranged in two displacement operation rows. In the embodiment of FIG. 3, only two displacement operation rows of the pattern thread guide needle 8 are provided, and the pattern thread is only arranged by a half gauge.

In the embodiment shown in FIG.
Is on the opposite side of the knitting needle 2 with the pattern yarn guide needle 8 interposed therebetween, and is separated from the pattern yarn guide needle by the drop plate 17. Thereby, when a pattern yarn is arranged with a full gauge, drop board patterning can be achieved. In the other embodiment shown in FIG. 5, only two displacement operation rows having the pattern thread guide needle 8 are provided, but otherwise correspond to the structure of FIG.

The pattern thread guide needles 8 can be moved by the jacquard control 16 to three different stable positions, each of which is offset from one another by one stitch 18. These three positions are indicated by the letter R in FIGS.
(Right), M (center), and L (left).

The basic displacement operation on the three knitting needles 2 is controlled by three-position control of the pattern thread guide needle 8 (three different positions as described later).
Combining comprising control to move to a stable position) and the possibility of total displacement operation was specified in a column ~e column of FIG. 6 is obtained.
When the pattern thread guide needle 8 maintains its position, the total displacement operation coincides with the basic displacement operation (row a). When the left end is switched from the right position to the center position, the total displacement operation under four needles (row b) is obtained, and when the left end is switched to the left position, the total displacement operation under five knitting needles is obtained. (Column c) is obtained. On the other hand, when the switch is switched to the center position at the right end, the total displacement operation only advances under the two hands (row d),
Switching to the left position at the right end provides a total displacement movement (row e) under one needle.

On the other hand, if the basic displacement operation under only two needles is selected, the possibility shown in FIG. 7 is obtained. The total displacement operation is under two needles (f row), under three needles (g row), under four needles (row h), under one needle (i
Row) and below the 0 needle (this corresponds to the float; j
Column) can be obtained.

The possibility of achieving the three stable positions of the handle thread guide needle 8 becomes apparent from FIGS. The first operating unit 19 and the second operating unit 20 are provided on the support 13.
Are arranged, and both can be operated from the jacquard controller 16. These operating parts are configured as piezoelectric bending transducers. The pattern thread guide needle 8 is fixed to the first operation portion 19, and can reciprocate in the direction of displacement by this operation portion. The operation unit 20 is movable across the same, and supports at its lower end a stopper block 21 that can move from the position of FIG. 9 to the position of FIG. 10 and vice versa. The stopper block 21 has four stoppers fixed in the bar direction. Figure 9
In the position, the left end stopper 22 and the center first stopper 23
Are effective, and the right end stopper 24 and the central second stopper 25 are effective in the position shown in FIG. That is, the book
The “three stable positions” in the embodiment refer to FIGS.
0, the pattern thread guide needle 8 is
When it is in the stopper 23 ( 25),
It means when it is in the topper 24. For other details, reference can be made to DE 196 51 053.8.

In the organization diagrams of FIGS. 11 to 16 described below, the chain knit formed by the ground yarn 4 is not shown. The thin solid line corresponds to the basic displacement operation of the pattern guide bar system 14, and the thick solid line corresponds to the actual gradient of the pattern thread 7.

The structure diagram in FIG. 11 is manufactured with the needle arrangement shown in FIG. 2 and utilizes the possibility of the displacement operation shown in FIG. e, under one knitting needle, in area b, under four knitting needles, area a
In the area c, yarns are supplied as partial wefts under three knitting needles and in the area c, under five knitting needles. The display of the area in this case corresponds to the column display of FIG. As can be clearly seen, the number of underlaps between adjacent wales is significantly different. The thickness of the pattern decreases from the area c to the area e through the area b, the area a, and the area d. As a result, a four-step thick and thin plane pattern having an extremely thick region, a thick region, an average region and a thin region is obtained. In the region e, the pattern thread 7 extends along the chain stitch, and an opening or a net portion can also be formed in the pattern.

The organization diagram of FIG. 12 is also manufactured by the needle arrangement of FIG. The basic displacement operation indicated by the thin line proceeds on the two knitting needles 2 as in FIG. Here, in the area j following the area i in which the total displacement operation proceeds under one needle, the pattern thread 7 is set as a floating thread. Next, a region f having a total displacement operation under two knitting needles, a region g having a total displacement operation under three knitting needles, and a region h having a total displacement operation under four knitting needles. There is. Accordingly, three areas f, g, and h, in which the number of underlaps of the pattern yarn 7 extending between adjacent wales gradually increases, that is, three-step thick and thin plane patterning can be obtained.

The organization diagram of FIG. 13 is also produced with the needle arrangement of FIG. 2 and has the three-stage basic displacement operation of FIG. 6, in which the pattern yarns 7 of different materials, in particular of different colors, are shown.
(Solid line) and 7 '(dashed line) are alternately woven.
The expression "color" also includes any other possibilities conceivable for various materials, including, for example, matte patterned yarns, glossy patterned yarns. In the area l, the pattern yarn 7 is supplied under five knitting needles, while the pattern yarn 7 'is supplied only under one knitting needle. The pattern yarn 7 forms two underlaps between adjacent wales and appears in a distinct color, while the pattern yarn 7 'fed along the chain stitch is hardly visible. A similar situation is obtained in the area m, where the pattern thread 7 'is fed under four knitting needles, and the pattern thread 7 is fed under one knitting needle.
Here, two colors clearly appear. The middle stage is the region n, o
Where one pattern yarn is fed under three knitting needles and the other pattern yarn is fed under one knitting needle. Other combinations providing various mixing effects can still be formed using the three positions of the pattern yarn guide needle.

14 is manufactured with the needle arrangement of FIG. 3 and has a basic displacement operation under three knitting needles 2. In this organization chart, the knitting needle 2 and the ground yarn guide needle 5 have full gauges. However, the two displacement rows of the handle thread guide needle 8 only have a half gauge in common. A region a having a total displacement operation under the three knitting needles is followed by a plurality of mixed regions having different total displacement operations in the weft direction. Areas a and e where the total displacement operation under three knitting needles and the total displacement operation under one knitting needle alternate, and the total displacement operation under four, five, two and one knitting needles Areas b, c, d, e where displacement operations are adjacent
And regions b, a, and c where the total displacement operation under the three, two, and five knitting needles is provided in the weft direction.

The connection region e has a total displacement operation under one knitting needle, and the region c has a total displacement operation under five knitting needles. In this way, a two-stage thick and thin plain pattern with half the number of pattern yarns is obtained.

The organization diagram of FIG. 15 is manufactured with the needle arrangement of FIG. 4 and is processed by a basic displacement operation under three knitting needles. Because of the falling plate pattern, the pattern thread 7 is looped,
The stitches of the chain stitch formed by the ground yarn 4 are combined. Here, too, the regions d, 1 with the total displacement movement under the two knitting needles
Area e having a total displacement action under four knitting needles, area b having a total displacement action under four knitting needles, area a having a total displacement action under three knitting needles, five The area c having the total displacement motion under the knitting needle and the other areas a and f are obtained. From this, a four-tiered and thin pattern can be obtained visually on the surface of the cloth thanks to the drop plate. The pattern yarn forms a true chain stitch in the region e, and a shifted chain stitch in the region f.
Therefore, a net structure is also possible.

The structure diagram of FIG. 16 is manufactured with the needle arrangement of FIG. 5, and has a basic displacement operation under the three knitting needles shown in FIG. Here, an area a having a total displacement action under the three knitting needles 2 is followed by mixing areas a and e, where 3
The total displacement operation under one knitting needle and the total displacement operation under one knitting needle alternate. Subsequent mixed areas b, c, a, d
In 4, the total displacement operation under the four, five, three and two knitting needles is continuous in the weft direction. In the mixing areas b and a provided thereafter, the total displacement operation under the four knitting needles and 3
The total displacement movement under the knitting needle of the book is continuous. Next comes region e, which has a total displacement movement under one needle, from which chain knitting of patterned yarns is also formed. Then, the area c of the total displacement operation under the five knitting needles comes. Also from this, a two-step thin pattern can be obtained on the surface of the cloth with half the number of pattern threads.

In many cases, it is sufficient to generate a pattern only by the above measures. However, additional effects can be achieved by adding other known patterns. As shown in FIGS. 14 and 16, the patterning changes not only in the warp direction but also in the weft direction. This also corresponds to the case where patterning is performed according to FIG. 11, FIG. 12, FIG. 13 or FIG.
