Abstract

SUMMARY OF THE INVENTION: A twine has two parallel shafts, each of which has two longitudinal holes. Rollers are located in the holes. The rods have grooves separated by jumpers. The grooves are inclined to the end of the rod at an angle of 45 [deg.] with 1 °. Flexible grooves are located in the grooves, covering grooved rings arranged obliquely and freely rotatable. The fabric in the process of working without bends and curvature enters the space between the upper and lower rods, sets in motion the flexible elements, due to which it expands. 1 s.p. f-ly, 4 ill.

Description

The invention relates to the textile industry and is intended for use on looms.

The essence of the invention is to improve the quality of the fabric.

The technical result that can be obtained by carrying out the invention is possible due to the fact that the rod in cross section has the shape of a bull with symmetrical curves with two longitudinal through holes, while the grooves in the area between the longitudinal holes are separated by jumpers, and the rings are installed in grooves of the rod by means of rollers located in the through holes, the width of the rings corresponding to the width of the grooves, the inclination of which increases from the middle to the ends from

1 to 45 °, the radius of the rings corresponds to the radius of the symmetrical roundings of the rod, with each pair of rings located on opposite sides of the corresponding bridge of the groove connected to each other by means of an infinite flexible element enveloping the outer surfaces of the rings having grooves corresponding to the profile of the flexible element.

The sheet can have one main or two rods, the second of which is parallel to the main one and installed with the possibility of changing the distance between the axes of the rods when dressing fabrics and adjusting.

An analysis of the causal relationship between the totality of the essential features of the claimed crib allows us to conclude the following:

the absence of excesses during the movement of the fabric helps to improve its quality due to reduced wear from friction;

the widening ability of the crib is significantly increased due to the location of the grooves and the guides located in them at an angle from 1 to 45 °;

the absence of needles eliminates tissue damage.

Fig. 1 shows a sheet, top view, cover removed; figure 2 is a section aa in figure 1; Fig. 3 is a view along arrow B in Fig. 1; figure 4 - section bb in figure 2.

The sheet (figure 1) consists of two parallel rods 1, 2, located one on the other (Fig.Z). The rod 1 is attached to the bed of the loom (not shown), and the rod 2 has (in any known manner) the ability to move when

wideness. Each of the rods 1, 2 in cross section has the shape of a bull with symmetrical curves and is equipped with two longitudinal holes 2 (Fig. 3), in which the rollers 3 are stationary. At least one of the rods 1, 2 is provided with grooves 4 (Fig. .4), separated by jumpers 5, inclined to the end 6 of the rod 1 at an angle a (Fig. T). The grooves located on either side of the middle of the stems (Fig. 4) are symmetrically and mirrored to create a shearing effect. Flexible elements 7 (Fig. 2) cover inclined grooved rings and have linear sections g (Fig. 2) with a length equal to the distance between the centers of the rollers 3.

The operation of the crib is as follows.

Moving in the longitudinal direction on the loom (Fig. 1) (during the usual forming process), the fabric 9 without bends and curvature enters the space between the upper 2 and lower 1 (Fig. 2) rods and is clamped between the rectilinear sections g of the flexible elements 7 inclined to the direction of its movement, mounted on the rings 8. The fabric 9, as it moves, moves the flexible elements 7, thereby expanding it.

Since the fabric 9 and the base 10 (Fig. 1) are strained, the most free movement of the fabric occurs only at the moment of surf, when its input tension is minimal. The rest of the time, starting from the moment the reed leaves (reed is not shown) until the last

As he approaches him to the front position, the crib keeps fabric 9 from any movement both in width and in length. The distance (Fig. 2) between the width bars can be changed when adjusting the expansion force depending on the properties of the fabric, changing the compression ratio of the flat sections of the elastic elements 7 holding the fabric 9. To fix the predetermined height of the edge of the fabric 9, a cover 11 of a conventional design is installed ( fig.Z). In order to uniformly increase the tensile force of the pile, the angle of inclination of the grooves 4 (Fig. 4) can progressively increase in the direction from the middle of the rod to its ends (Fig. 1).

The punch is designed for light and medium tissues.

The installation of the cotter is possible on any loom and does not affect the operation of other elements. The working boat is controlled by a bird.
