Description

The invention relates to weaving and can be used in the manufacture of yarn fabrics.

The purpose of the invention is to improve the quality of the fabric being woven by reducing the deformation of the base yarn.

FIG. 1 a-g shows a step-by-step scheme for obtaining a loop of a weft yarn; FIG. 2 shows the technological scheme of the device for the implementation of the method, type c; in FIG. 3 a section in FIG. 2

The method of obtaining an elastic web is carried out with the help of a device that includes 1 shuttle 2 installed in a stationary open body with a spout 3 on the side surface for gripping the main and weft threads. Shuttle 2 is installed in case 1 with the possibility of rotation about a horizontal axis and provided with a cut-out 4 on the outer surface in front of the spout 3, Cut-out 4 forms a window with the inner surface of the fixed non-closed housing 1 for the main thread 5, Inside the shuttle 2 there is a package 6 with weft thread . Shuttle 2 is connected to gear 7, which is kinematically connected with a cog wheel 8. The device is also equipped with a lever 9, a swinging movement and supply 1 main thread 5 to the spout 3 of the shuttle 2, and the bottom plates 10.

The method for producing the elastic web is as follows.

The main threads 5 are alternately folded by the lever 9 and guided into the zone of action of the nozzle 3 of the shuttle 2. The free portion of the weft thread 1 1 is held) 5IV by means of winding with the previous main thread 5 (Fig. 1a).

Shuttle 2 turns, with its nose 3, turning the main thread b and weft thread 11 (FIG. 1, b), the stock of which is located in the shuttle in the form of a package 6.

Shuttle 2 turn further, moving the main thread 5 in the window 4, formed between the non-closed non-connected case 1 and the shuttle 2; and bending the main thread 5 weft thread 11 J we wind along with the package b (Fig. 1, h).

The nose 3 of the shuttle 2 drives the main thread 5 to the upper position, moving it in window 4 between the unlocked stationary housing .1 and the shuttle 3. and outside the shuttle, between the teeth of the drive gears, completely wrapped with the weft thread 11, the main thread 5, from a weft yarn 11, a closed loop around the main yarn 5, winding the weft thread for etog from the package b (Fig. 1, e).

The axis was further rotated by the shuttle 2. The main thread 1 was mixed in the window 4 and, together with it, the loop of the weft thread 5 formed around it (Fig. 1, e).

The main thread 5 under the action of its tensioner is retracted from the zone of action of the spout 3 of the shuttle 2 beyond the limits of the unlocked stationary case, and the reel of the weft section 1 1 (FIG. 15) wrapped around the main lii-rere 5 is withdrawn.

METHOD FOR PRODUCING ELASTIC DRAWINGS by grafting the warp and weft yarns with the formation of a loop from one of them when the warp yarns are deflected, folding the weft yarns while winding them from the package placed in the spacer, and surfing the weft yarns to the edge of the fabric, characterized in that , in order to improve the quality of the fabric produced by reducing the deformation of the main threads, a loop is formed from a weft thread when it is laid, which is carried out using a cylindrical shuttle having a spout on the side surface, while rotating it relatively horizontal axis, the deflection of the main threads is carried out sequentially by bringing each of them into the area of the spout of the plotter, and when forming a loop, the weft is bent around the main thread, followed by the discharge of the twisted main thread. | SsEsd> oe
