Description

Machines are known for producing tulle from the shuttle nnten and a closed row of nz crossing threads of the warp, equipped with movable shuttles with spools, a cushion of w with warp threads moving in one direction along a closed contour drawn along the line of the tulle production and moving around this the warp lines of the warp yarns forming two endless rows moving towards each other.

In these masts, the base rollers with H1tm move together with the thread guides stepwise and progressively to ensure that the warp threads intersect, that the performance of the machine due to the inertial forces that occur when reciprocatingly moving the relatively heavy coils together with the thread guides and complicates their drive movement.

In the described machine, the noted disadvantage is eliminated by the fact that the stepped and translational movements inform yarn feeders independently of the translational movement of the base coils. To accomplish this, the machine is equipped with two endless pivot chains, moved by drive and tension sprockets, each set obliquely one to the other under an acute angle facing upward on the reciprocating movable slide, each carrying the thread carriers attached to their links by means of screws. angle combs.

In order to eliminate the arbitrary slipping of the warp threads from the combs, the machine is provided with a fixed strip with longitudinal grooves for the teeth of both rows of combs, which are freely included in them, installed between the upper converging branches of both chains.

The machine is equipped with movable shuttles / carrying spools 2 with threads 3 and moving reciprocatingly along the guide 4 by means of gears in the form of gear rollers 5. The naravlye 4 are fixed on bars 6, shifted in the direction opposite to the plane of the drawing for intertwining the shuttle threads 3 with threads 7 bases. Tulle 9 is formed from the main n shuttle threads at the baffle 8.

The coils 10 (Fig. 3) with the warp threads 7 are placed in a closed contour 11, stretched along the web of the produced tulle, and move in one direction, according to the arrow B. The machine is equipped with thread yarns of the warp threads moving in the same direction , made in the form of two rows of filaments 12 bent above the corner (Fig. I, 3, 4 and 5). The comb through screws 13 (fig. 1, 4, and 5) are attached, with the possibility of replacing these combs, to the links 14 of two articulated chains, which are guided by the drive and tension sprockets 15 (fig. 1 and 2) each.

The sprockets are set obliquely to one another at an acute angle on two drive sled 16, reciprocatingly moving along arrow G (Fig. 2).

To eliminate the possibility of arbitrary slipping of the yarns 7 (fig. 1) of the base of the dies 12 (figs 1, 3, 4 and 5), the machine is provided with a fixed strap 17 (figs 1, 2 and 3) fixed to the rods x 18 (fig. 1 and 2).

The machine is equipped with driven ends of a nlanka 17 driven yarn guide 19 (Fig. 2), mounted by means of its axes 20 on a skid 16 and carrying out the transfer of the warp yarns 7 from one dies 12 to others.

The production of tulle on the described machine is as follows. The drive of the machine moves but the closed contour of the roller 10 with the warp threads. At the same time, the guide cages 12, mounted on links 14 of the hinged chains, move in one direction in the same direction.

Movable reciprocating postunal across and along the plane of the produced cloth 9 shuttles / non-intertwining shuttle threads 3 with threads 7 tulle bases, carried out the interweaving of these threads in a predetermined pattern.

Claims (2)

1. A machine for producing tulle from the shuttle threads and a closed row of intersecting warp threads, equipped with movable shuttles with spools, spools of warp threads, unremovable in one direction but closed contour, stretched along the line of the tulle production, and mixing around this the warp yarn lines are yarn feeders, forming two endless rows moving towards one another, characterized in that, in order to simplify the yarn feeders and drive them and ensure the stepwise and progressive movement of yarn feeders, Depending on the movement of the thread rolls of the base, it is provided with two endless pivot chains moved by the drive and tension sprockets each set obliquely to one another under an upright acute angle on the reciprocating movement of the slide each of them and carrying thread carriers attached to their links by means of screws in the form of bent nodes nod angle. 2. The form of the machine according to claim 1, characterized in that, in order to eliminate the arbitrary slipping of the warp threads from the combs, it is provided with a fixed plate with longitudinal grooves for the teeth of both rows of combs that are freely included in them, mounted between the upper converging branches of both chains.
