Such an object is achieved by a warp knitting machine which carries the features of claim 1 in terms of the apparatus.

As will be described in detail below, such warp knitting machines can obtain warp knitted fabrics in which three or more dense / coarse patterns are placed or two-tone patterns. In that regard, long-distance blanket movements over four or more crochet needles are made to realize the formation of dense glyph zones or the manifestation of color tone, combining the basic movement with a crochet needle that can occupy two or more positions. This is important because it allows for delicate stepping between different densified glyph zones and a delicate transition from one hue to another.

According to the configuration according to claim 2, the fringes that form the basis of the knitting together with the glyphs are floated by a single base knitting bar, and the transition from the flat glyph to the reticulated glyph by guiding the glyphs correspondingly. It becomes possible.

The configuration according to claim 3 allows a three-level dense / coarse pattern to be placed and a entangled pattern section to be provided.

According to the configuration according to claim 4, it is possible to provide a global movement over the five crochet needles to place a correspondingly staged dense / coarse pattern.

When arranging the blank knitting bar as claimed in claim 5, the pattern is placed in the blank of the knit fabric.

When arranging the blank knitting bar as claimed in claim 6, the pattern is placed on the blank of the knit fabric.

In the arrangement according to claim 7, a density corresponding to the complete knitting density of the loom is given to the glyph knitting needle. Although there are components necessary to position them in multiple positions, the glyph knitting needles do not interfere with each other.

In an optional configuration according to claim 8 the number of knitting needles is only 50% of the number of nasal knitting needles. In such a form, a stepped pattern can be placed.

According to the configuration according to claim 9, it is possible to provide three positions of the pattern knitting needle at a reasonable cost. The second control member is preferably moved across the movement direction of the pattern knitting needle. In particular, the control member can be a piezoelectric curved transducer as described in detail in DE 196 51 053.8.

The object of the invention as set out is achieved by the features of claim 10 in terms of method.

The liquor of the base yarn according to claim 11 is possible because the liquor is ligated by a glyph.

The degree of gradation of pattern placement is increased by claim 12.

Claim 13 enables the transition from a flat pattern laying to a mesh pattern laying.

Knitting patterns according to claims 14 and 15 are common in that glyphs participate in forming the basis of the knitting. However, visually different glyphs are placed.

The feature of claim 16 places a very prominent dense / coarse pattern.

Claim 18 relates to a novel knitted patterned warp knit, wherein such knit areas are created with pattern areas placed at different concentrations or densities depending on the number of pattern yarns present in the purl.

The number of stages of staged patterns can be increased by the configuration of claim 19.

The configuration according to claim 20 makes the transition from a planar pattern to a network structure. Claim 21 discloses a novel form of warp knitted fabric with a two-tone pattern. If only one hue of the two tones is present in the purl, the hue is prominent. When both tones are present in the purl, a staged blend of both shades is achieved.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments shown in the accompanying drawings.

The working zone 1 of the warp knitting machine of FIG. 1 has a series of crochet needles 2 in the crochet needle bar 3. The base yarn 4 floating to a density corresponding to the complete knitting density of the loom is supplied via a base yarn knitting needle 5 mounted on the base knitting bar 6. Such background knitting bars 6 are capable of reciprocating movement, for example in connection with tricot floats. However, it is preferable that the blank knitting bar 6 produces a liquor that forms the ground by mutually joining with the use of the pattern yarn 7 described later. The glyph yarns 7 are supplied via the glyph knitting needles 8 arranged in the four moving rows 9, 10, 11, and 12 at a density of ¼ of the knitting density of the loom. 9, 10 11, 12 are held by the support 13. In such a form, a glyph bar system 14 is formed in which the glyph knitting needles 8 are placed at the complete knitting density of the loom. Such a system has a common basic movement, for example over three crochet needles 2 (FIG. 6) or over two crochet needles 2 (FIG. 7). The basic movement control device 15 shown only implicitly is for basic movement, and the jacquard control device 16 also shown only implicitly is for movement of the pattern knitting needle 8.

An enlarged view of the needle device of FIG. 1 is shown in FIG. 2. The ground thread knitting needle 5 is disposed between the nose knitting needle 2 and the pattern knitting needle 8 arranged in four moving rows. In the embodiment according to FIG. 3, only two rows of movement of the glyph knitting needle 8 are provided, so that the glyph yarns are arranged at a density of half the knitting density of the knitting machine.

In the embodiment according to FIG. 4, the base yarn knitting needles 5 are disposed on both sides of the nose knitting needles 2 and the outer surface of the pattern yarn knitting needles 8 so that the pattern yarn knitting needles 8 are formed by the fall plate 17. Separated from. Thereby, a fall pattern can be placed in a pattern yarn arranged at a density corresponding to the complete knitting density of the loom. In FIG. 5 only two moving rows with a patterned knitting needle 8 are provided but the rest of the configuration is shown the same variant as in FIG. 4.

The glyph knitting needles 8 can be moved by the jacquard control device to three different stable positions, each separated by a needle passage 18. Such three positions are indicated in FIGS. 6 and 7 by the letters "R" (right), "M" (center) and "L" (left), respectively.

Combining the basic movement over the three crochet needles 2 with the three-position control of the glyph knitting needles 8, the overall movement scheme as given in the "a" through "e" rows of FIG. 6 will be realized. Can be. When the glyph knitting needle 8 is kept in its original position, the overall movement coincides with the basic movement (the "a" line). If it is moved from the left end to the right position to the center position, a global movement within four crochet needles is obtained (line "b"), and if it is moved from the left end to the left position, the overall movement within five crochet needles is achieved. Is obtained ("c" line). On the other hand, if it is moved from the right end to the central position, there is a global movement within only two crochet needles (line "d"), and if it is moved from the right end to the left position, it is within one crochet needle. A global move is made (line "e").

On the other hand, if the basic movement over only two crochet needles is selected, the global movement shown in FIG. 7 can be achieved. That is, a global movement across two crochet needles ("f" row), a global movement across three crochet needles ("g" row), a global movement across four crochet needles ("h" row), Overall movements within one crochet needle (“i” row) and global movements within zero crochet needles (ie corresponding to thread entanglement, “k” rows) can be obtained.

8 to 10 it is possible to find out how the three stable positions of the patterned knitting needle 8 are reached. The support 13 is provided with a first control member 19 and a second control member 20 which can be operated from the jacquard control device 16 side. Such control members 19, 20 are formed as curved transducers by piezoelectricity. The pattern knitting needle 8 is fixed to the first control member 19 and can be reciprocated in the movement direction by the first control member 19. The second control member 20 can be moved across the direction of movement of the patterned knitting needle 8 and supports the stopper block 21 at the lower end, which stopper block 21 is shown in FIG. 10 from the position of FIG. And vice versa. The stopper block 21 has four stoppers fixed to the bar side. Among them, the left end stopper 22 and the first center stopper 23 act in the position of FIG. 9, and the right end stopper 24 and the second center stopper 25 in the position of FIG. 10. Do it. For further details see DE 196 51 053.8.

In the knitting operations of FIGS. 11 to 16 to be described later, the liquor formed by the base yarn is not shown. The thinly drawn lines correspond to the basic movement of the glyph bar system 14 and the thickly drawn lines correspond to the glyph's actual path.

In the knitting operation according to FIG. 11 made by the needle device of FIG. 2 and using the movement scheme of FIG. 6, the glyph 7 spans within two nose knitting needles in the “d” zone, “e”. Within 1 nasal crochet needle in the zone, within 4 nasal crochet needles in the "b" zone, within 3 nasal crochet needles in the "a" zone, and within 5 nasal crochet needles in the "c" zone, respectively. Knitted as a partial weft. In that case, the zone name corresponds to the name of the row in FIG. 6. From this, it can be clearly seen that the number of purl between adjacent nose bars is very different. That is, the density of the pattern laying decreases from the "c" zone to the "e" zone via the "b" zone, the "a" zone and the "d" zone. Thereby, four levels of dense / coarse planar patterns are laid out by very dense, dense, intermediate and coarse zones. In the "e" zone, glyphs 7 may extend along the tufts, forming gaps or nets in the pattern.

The knitting operation of Fig. 12 is also made by the needle device of Fig. 2. The basic movement, drawn in thin lines, is carried out over two crochet needles 2 as shown in FIG. 7. Such work diagrams are followed by an "i" zone in which collective movement is carried out within one crochet needle, followed by a "k" zone in which the glyphs 7 are entangled. Subsequently, the "f" zone entails global movement within two crochet needles, the "g" zone entails global movement within three crochet needles, and the "h" enclosing global movement within four crochet needles. "Area is provided. Correspondingly, three zones are given, "f", "g" and "h", in which the number of purl's purl extending between adjacent nose bars is gradually increased. That is, three levels of dense / coarse planar patterns are placed.

In the knitting operation diagram of FIG. 13, which is also made by the needle device according to FIG. 2 and has a basic movement across three crochet needles according to FIG. 6, a pattern consisting of different materials, in particular of different shades of material. Yarn (7) (solid line) and glyph (7 ') (dotted line) alternately float. In that case, the expression "hue" encompasses all other possibilities that can be considered for different materials such as, for example, matte and gloss. In the " l " region, the glyph 7 floats within five crochet needles, while the glyph 7 'floats within only one crochet needle. The glyph 7 which performs two purlations between adjacent nose bars shows vivid hue, while the glyph 7 'which is placed along the tuft is hardly noticeable. A similar situation also occurs in the "m" zone where the glyph 7 'floats within four nasal needles and the glyph 7 floats within only one nasal needle. In such zones two shades are vividly expressed. Intermediate stages of color tone occur in the "n" and "o" zones, where one glyph is floated within three nasal needles and the other glyph is floated within one nasal needle. Three positions of the glyph knitting needle can be used to create another combination that induces different mixing effects.

In the knitting knitting operation of FIG. 14 made by the needle device of FIG. 3 and with basic movement within three nasal knitting needles, the crochet knitting needle 2 and the ground thread knitting needle 5 have a complete knitting knitting of the loom. While a density corresponding to the density is given, two moving rows of the pattern knitting needle 8 are commonly given a density corresponding to half of the knitting density of the loom. The zone “a”, which involves global movement within three crochet needles, is followed by a number of mixing zones that involve different global movements in the weft direction. That is, the overall movement within the "a", "e" regions, four, five, two and one nose needles, in which the global movement across three crochet needles and the global movement across one crochet needle are alternating. "B", "a", "where movements are confined to the adjacent" b "," c, "d", "e" zones, and collective movements within three, two and five crochet needles in the weft direction. c "zone. The starting zone" e "zone is given a global movement within one crochet needle and the" c "zone is given a global movement within five crochet needles. Two levels of dense / coarse, flat patterns are placed.

The knitting operation diagram of FIG. 15 is made by the needle device according to FIG. 4, and the operation is carried out with a basic movement within three crochet needles. The glyph 7 is ligated as a ring in the nose of the liquor formed by the base thread due to the dropping of the drop pattern. In that case too, the "d" zone entails global movement within two crochet needles, the "e" zone entails global movement within one crochet needle, and the ensemble movement within four crochet needles. "b" zone, zone "a" involving global movement within three crochet needles, "c" zone with global movement within five crochet needles, and additional "a" zone and "f" zone This is provided. Thereby, four levels of dense / coarse glyphs are placed, but the glyphs do not appear to be in the same plane as the plane of the knit, but appear to be on the knit due to the fallout. The glyphs form typical tufts in the "e" section and displaced tufts in the "f" section, so that a reticulated structure can also be achieved.

The knit knitting operation of FIG. 16 is made by the needle device according to FIG. 5, with basic movement over three crochet needles as shown in FIG. 6. The "a" zone followed by a blanket movement across the three crochet needles is followed by an "a", "e" mixing zone where the blanket movement across the three and one crochet needle is alternating. Subsequently, a "b", "c", "a", "d" mixing zone is provided in which overall movements within four, five, three and two crochet needles are continuous in the weft direction. Subsequently, a "b", "a" mixing zone is provided in which the overall movement within four and three crochet needles is continuous. Subsequently, there is provided an "e" zone, which involves a blanket movement within one crochet needle and also causes the glyph to form tufts, and a "c" section, which involves a blanket movement within five crochet needles. Thereby, two levels of dense / coarse pattern are also placed on the surface of the knitted fabric, which is half the number of pattern yarns.

In many cases, glyph placement is made entirely by the aforementioned measures. However, additional effects may be obtained by further adding known patterns. As shown in Figs. 14 and 16, the pattern may be placed not only in the warp direction but also in the weft direction. The same applies to the case of performing the pattern placement corresponding to FIG. 11, 12, 13, or 15.

According to the warp knitting machine according to the present invention, a method of producing a warp knitted fabric and a warp knitted fabric, the long-distance general movement is carried out over four or more crochet needles to realize the formation of a dense pattern area or the expression of color tone; Combining the basic movement with knitting needles that can occupy two or more positions allows for finer stepping between different densified glyph zones and a delicate transition from one hue to another, resulting in more than three levels of dense A new type of warp knit can be obtained with either a long / long pattern or a two-tone pattern.
