A fabricator made with a leno weave works as follows. Before the movement of the device 4 for the staple yarn with this thread 7 is in the position of the lower pharynx and in this position is indicated by the position 7G. The base member 16 is supported on the base 20 of the gap 13 (Figures 1 and 2a). If the winding weave 14 of the openwork weave moves downwards through the lower leg 15 along the track 11, then it passes the guideway 14 of the openwork weave is in the position of the upper mouth in the left track 11. The needle

The plowing element 16 is in the passageway 24 and slides off through the inclined base 20 in the direction to the right (there it is indicated by the position 14). At the same time, the needle 4 with a yarn thread 7 of the interlacing from the heddle frame 3 moves upward to the position of the upper shed. The stitching thread 14 of the openwork weave and the stitching thread 7 of the twisting intertwining intersect with each other, while the winding thread 14 of the openwork weaving crosses the insertion weave 28 from above, and the stitching 7 of the winding weave - from the bottom. Thus, the weft thread 28 becomes connected (FIG. 3).

Then the next weighted thread 29 is inserted. At the next change of the throat, the winding thread 14 of the openwork weave rises, while it crosses the weft thread 29 from the bottom. When it moves in the upward direction, the winding thread 14 of the openwork weave pushes the guide element 16 to the left and creates a passage 30 between its shoulder 19 and the inner side 22 of the yarn feeder for the winding thread of the openwork weave (Fig. 26) and from there goes to the right track 12. The thread 7 of the winding weave moves simultaneously in the downward direction and in the polo Appendix 7, wherein it crosses the top weft yarn 29. The guiding member 16 slides back to the position marked in Figure 2B. After the next weft yarn 31 is introduced, a subsequent change of the pharynx follows, with the winding yarn 14 of the openwork weaving moving downward to the track 12, the holding yarn 7 of the winding weaving upwards. The lanyard 14 of the openwork weave slides through the passage 26 between the middle web 10 and the right shoulder 19 and enters the opening 17 of the guide member (Fig. 2c). At the next change of the throat, the winding thread 14 of the openwork weave moves upwards, displaces the guide element 16 in the left direction and creates a passage 32 between the tapered part 10 of the middle jumper 10 and the left shoulder 18 of the guide element (Fig. 2d). During upward movement of the winded thread

14, the openwork weave on track 11, the staple thread 7 of the leno weave moves downward. In this way, the leno loop ends.

If the fabric should be provided with a cut edge, i.e. with two adjacent edges made

Q by the interlining weave, between which the fabric must be divided, the device is doubled (FIG. 4). Both fabrication devices I and II, made with a weave, are formed on a common base 33. Device I, which is made with a weave and made weave, consists of a yarn feeder 34 for the yarn

0 an openwork weave with a guide element 35 and a needle 36 for a stitching winding thread. The guide element 35 is U-shaped and has two arms 37 and 38, which surround the middle jumper 39. The guide element 35 passes through a thread in the yarn feeder for an openwork interlacing. For this, the outer side of the shoulder 37

0 has a groove 40, the protruding edges 41 and 42 of which cover the base 33 with a sufficient gap to pass the lace weave 43. The same applies to the outer side of the shoulder 38 of the guide element 35. The thread guide 44 for the curling thread of the openwork weave of the fabric manufacturing apparatus II, made by the graft web, is constructed in the same way. Each of the devices I and II operates in the same way, as discussed for the device in FIGS. 1 and 2a-b, but asynchronously. Thus, two arise: the edges 45 and 46 of the fabric, made by the interlacing, with the cutting edge 47 located between them, where the fabric is later separated

l (6). This doubling is also applied when, for example, is woven in the presence of a very smooth yarn. The number of devices depends on the current requirements. Referring to Fig. 7, the yarn feeder 48 for the laced yarn of the openwork weave has a U-shaped guide member 49 in the form of a wire formation of spring wire.
