Description

A weaving loom with a wave-shaped shed is known, which contains a grill with a channel for a weft thread plotter, a movable reed formed by a helical set of plates on the shaft, provided with teeth to prevent the weft thread plotter from moving. In this weaving loom, a grid with a channel for a weft nanthi made of fixed plates creates an inconvenience in maintenance and also reduces the reliability of the machine.

In the proposed loom to increase the reliability of its operation, the grating with a channel for the weft liner consists of two parts, one of which is stationary and the other is pivotally mounted on the first and interacts with the weft thread plotter, and the weft thread plotter is made in the form of paired polyhedra, have channels for weft threads and brake jaws.

FIG. 1 is a side view of a grate with a channel for a weft yarn and a movable reel; in fig. 2 - weft plotter; in fig. 3 - weft plotter, section along A-L on fng. 2; in fig. 4 is a diagram of the mutual arrangement of the details of the grid and reed.

Cutting the pads with 3 rods 4 and mounted on the support 5 of the machine Between the plates of the lattice, the enters of the thread of the base 6 are placed. The plates of the lattice 2 partially form a channel 7 for the passage of the weft yarn plotter 8 9. The lattice consists of two parts, one of which is fixed and the other 10 is mounted movably on the hinge 11 of the first part of the lattice and is attached to her spring 12.

The loom of the weaving machine is formed by a set on the shaft 13 of the plates 14. The plates 14 are assembled on the straight key 15 of the shaft 13, the keyway of each plate is mixed with respect to the groove of the preceding Clashes by the angle necessary to form the screw surface of the teeth of the 16 plates 14, which serve to move the weft yarn 8 and bring it to the edge of the fabric 17.

Between the plates of the lattice and the plates 14 byrd, plates-strips 19 fastened on the chest 18 of the machine tool are placed, which guide the teeth 16.

the form of paired polyhedra 20 and 21, each of these polyhedra has a channel 22 for weft threads 9 n spring-loaded brake jaws 23. For charging the weft thread plotter nozzle 24 pointed

spring-loaded sponge 23 and blows into the channel 22 a measured segment of the weft thread 9.

During operation, the process of laying the weft yarn and forming the fabric is carried out by moving the plotter 8 of the weft thread through the channel 7 in the sheds of the warp 6 as a result of the interaction of the teeth 16 of the plates 14 receiving rotation from the shaft 13 with the bevels 25 of the weft thread plotter. The weft yarns 9 are laid and nailed by the teeth 16 to the edge of the fabric 17.

A cantilever with channel 7, consisting of two parts, fixed and movable 10, allows, if necessary, to quickly remove from the channel 7 or to insert into it a plotter 8 of the weft thread.
