Description

The invention relates to a crocheted weave formed by knitted warp by interlacing, including looped poles, and between them mutually on the basis of weaving weave, a repetitive basic and weft system formed by the connecting broach of the looped poles.

Known in the stitched webs formed by knitted warp basal weave, consisting of looped columns, between which are placed the main thread, interlacing with the connecting broaches on the basis of weaving. The data in non-woven canvases, cited, for example, in Czechoslovakia patents N 146269, cl. D 04 W 39/06, 1977, ed. St. USSR № 162119 and ed. St. USSR Ns 162120, manufactured on-the-job in the hall machine according to ed. St. USSR No. 153246. based on the principle of laying elements deviating (swinging) in an open shed.

From the point of view of the significantly different processing of the main and weft yarns, each thread system is wound on an independent shaft, or weft yarns are fed from a spool mounted on the machine. This installation is difficult in terms of placement.

German application DE-OS 2034120, cl. D 04 B 39/06, 1969 describes both into zapped cloths formed by knitted warp basics by weave interlacing, including looped poles and, based on weaving weave, mutually intertwining main and weft systems, formed by connecting broaches of looped poles.

This type of fabric could be made on a weaving-in a haunting machine, in the German application DE-OS 2034120, in which the haul mechanism of this machine is formed in loops of needles, flankingly moving reed. The last two form layers

items in the hall mechanism. However, this weaving machine is not used in practice because of a number of disadvantages; Especially because when laying weft threads on hooks in the hallways or by lateral movement of the bead, the base is also stiffened, and the resulting web is held in the surf strip only by the loops caught in the needle needles. The transverse movement of the reed with the main and weft threads takes place with open throat, when the tension of the warp is the highest and reaches approximately 1000-1500 N per 1 m width of the warp.

However, it is possible to produce in a new type of weaving machine in a dressing machine, in the hall mechanisms of which are formed by the helix eyes of the heald or jacquard mechanism in the function of laying elements and the system in the needle needles moving in the first open mouth from their original position, in which they are parallel to the main threads, to the left paving position to the original position, and in the second open throat - to the right curse dyval position and back to its original position. This new type of weaving machine is similarly equipped with two shafts for main and weft threads.

The task of the invention is to design a new type in a rolled-up canvas, which would simplify the weaving-in the intake machine.

This condition is essentially fulfilled in a knitting fabric formed by knitting warp by interlacing, including looped poles and, inter alia, based on weaving weaving, the interlacing main and weft systems formed by the connecting pulls of the looped poles, according to the invention. that, in the repeat of the weave, the data of the rows and columns have, for all the yarns of the knit base of the hall weave, no-essentially the same processing.

In the repeat pattern of the interlacing of a pair of connecting wires, coming out of one loop and always connecting a pair of columns, the next two columns are placed between them; at the transition between the columns of this pair of columns, they mutually intertwine in the weft system and the main system.

The formation of the weft system means that the connecting weft in the relevant area is intertwined like a duck with a connecting one.

which are intertwined in the main system at the corresponding site, and vice versa, the formation of the main system means. that the connective stretch is intertwined in the corresponding section of the rapport

0 interlacing as a base with interlocking broaches that interlace in the corresponding section of the interlacing of the interlacing in the weft system.

According to one of the primary

5 samples in a rolled-up web forms one of the connecting strings of a pair of connecting stitches when passing between a pair of posts a weft system, while the second connecting stitch of the same pair of connecting stitches forms a sequential weft system, the main system and the weft system.

According to a subsequent advantageous embodiment in a rolled-up web 5, both connecting paths between pairs of columns are interlaced, successively based on weft interlacing, main and weft interlacing. In the repeat pattern of interlacing, the number of rows is always a multiple of the number of bars. A new type in a rolled-up cloth according to the invention allows the manufacture of this product on a weaving in a haul machine. equipped with a single shaft for the yarns of knitwear basics of the meshed interlacing, and also expands the range of zipper fabrics for attractive non-paring webs.

During the development of the need to

0 adjust the length of the yarns between the shaft and the surf strip of the textile cloth by convenient, known means, for example, using a device for compensating the tension force of the thread.

5 The exemplary designs in the folded web according to the invention are schematically shown in FIGS. 1 and 2.

The knitted warp knit 1 of the yarn system 2. is characterized by columns 3 loops 4. forming rows of 5. The columns 3 are connected by connecting rods 6a, 6b. exiting from one loop 4.

The rapport S weave forms so5 according to figure 1, four columns 3a-3d and eight rows. The columns 3 are arranged in pairs For, 3d and 3b, For, and the columns of each pair are always separated by two successive columns 3. In this case, a pair of columns are For. 3d separated by columns

ЗЬ Зг, and a pair of columns ЗЬ З by columns Зс. 3d, etc.

From loop 4, for example, column Za and row 5a indicated, there is a pair of connecting wires 6a, 6b, which form in row 5a, parallel to the gap 7 between columns Zb. The weft system A. Next, the connecting broach 6a continues in the same gap 7. in the opposite direction, unlike the connecting broach 6b, to the next row 5b, in which it forms up to column 3d. also the weft system A, Connective broaching 6B continues in gap 7. six rows of 5h, 5g. 5f, 5e, 5d. 5c to pd-5b in the main system B. then continues in this row of 5b up to the 3d column again in the weft system A.

According to FIG. 2, a pair of connecting rods 6a, 6b is formed from loop 4, for example, column Za and rowa 5a. in p de 5a. in parallel to the gap 7 between the columns 3b, 3c, the weft system A. Then the connecting broach 6a in the gap 7 continues through four rows of 5L-5e, up to the row of 5f. From the main system B, and then to column 3d again in the weir system. The connecting broach 6b passes in the gap 7 in the opposite direction, in contrast to the connecting broach 6a, through two rows of 5h, 5g to row of 5f. in the main system B. and later in the same row de 5f to column 3d in the weft system A. Also in this case, rapport S forms four columns 3a-3d and eight rows 5a-5h.

The zapped cloths of Figs 1 and 2 are made on a weaving and dressing machine, the hall mechanisms of which are formed by the eyes of the hem of the hem or Jacquard as a function of the laying elements and the system in the needle needles. moving in the first open mouth from its original position, in which they are parallel with the main threads, to the left feed position and back to the original position, and with the second open mouth, to the right feed position and back to the original position.

In order to fabricate the woven webs according to the invention, it is necessary for the needle needles in their original position to be guided between the laying elements.

Pale remise or Jacquard take both upper and lower positions to place the threads in the upper or lower branches of the pharynx, in accordance with the weaving, and also occupy the feeding position that is different from the above upper and lower positions, e; corresponding thread on the needle of the needle, which is in the feed position, according to the repeat of the knitted warp knitting.

Each rapport S of the weave pattern is always defined by four columns 3, this is given by the above arrangement in the hall mechanism. The number of rows in the repeat of the weave is always even depends on how long the individual yarns 2 of the knitted bases intertwine - the meshed weave 1 in the main system B. During the weave of the corresponding thread 2 in the main system B, this thread alternates between the top and bottom branch x throat, according to the weaving weave. From this it follows that it is possible to form various variants of knitted base webs, according to the length, or after how many rows of this interlacing, the corresponding thread in the main system is woven.

Obviously, for some simple knit basics of entanglements, a remise is sufficient, controlled by a heald carriage. For more complex weaves it is necessary to use

jacquard machine.
