Abstract

The invention relates to textile machinery, can be used on weaving machines in the development of dense technical fabrics and allows you to expand the technological capabilities of the machine by providing the ability to change the stiffness of the elastic dressing. The main yarns 11, going from side to side 3, bend around the motionless rock 1 and the movable rock 4. Then roll 6 and skew around the roll 5. Skip angles around the rollers 5 and 6 of the base stitch 11 allow individual adjustment of the rolls 5 and 6. The rigidity of the elastic filling of the machine, depending on the fabric article number. In addition, the roller 5 allows adjusting the tension of the warp branches that were cut into the remises to expose the spade line. Hard fixation of the rollers 5 and 6 on the additional roller allows to reduce the load on the movable rock 4 at the time of formation of formation and the gear, to reduce the oscillations of the movable rock 4. 1 sludge.

The invention relates to textile machinery and can be used on weaving machines in the development of dense and technical fabrics.

The aim of the invention is the expansion of technological capabilities by providing the possibility of changing the stiffness of the elastic filling

The drawing shows a device for tensioning warp threads on a loom.

The device for tensioning the warp threads comprises a fixed rock 1 mounted on the frame 2 of the machine between Navoy 3 and the movable rock 4, and a pair of rollers 5 and 6 mounted behind the movable rock 4 along the movement of the warp threads of the rollers 5 and 6, one in 5 brackets 8, and the other 6 is mounted in brackets 9. An additional roller 10 is mounted on the frame 2 of the machine under a pair of rollers 5 and 6, while the brackets 8 and 9 are mounted on an additional roller 10 with the possibility of angular rotation for individual adjustment of rollers 5 and 6 height and depth of the machine.

The individual adjustment of the rollers 5 and 6 to the height and depth of the machine allows changing the rigidity of the elastic filling of the machine by periodically changing the tension of the warp threads.

When the machine is in operation, the main threads 1 going with 3, go around the stationary rock 1 and the movable rock 4. Then roll 6 and the roll 5 on top. Change the pick angles of the rollers 5 and 6 with thread 11 of the base by individually adjusting the rollers

Tensioning the branches of the warp, which were cut into remises, set the spade line. Hard fixation of the rollers 5 and 6 on the additional roller allows reducing the load on the movable rock 4 at the time of formation and surfacing, reducing the oscillations of the movable rock 4o 1 silt.

5 and 6, it is possible to quickly change the rigidity of the elastic filling of the machine, depending on the article of cloth produced on the machine. So, when fabricating a Filtropress, the position of the roller 5 should be at an angle of 80 ° to the horizontal, and the roller 6 should be at an angle of 90. In addition, the roller 5 allows adjusting the tension of the warp branches that were cut into the remises to expose the spade line.

Hard fixation of the rollers 5 and 6 on the additional roller 10 reduces the load on the movable rock 4 at the time of formation and surfacing, reduces the oscillations of the movable rock 4 and the uneven tension of the threads in the machine cycle.

The invention allows to expand the technological capabilities of the shuttleless weaving machine, for example, the type of STB, when making technical

5 and especially dense fabrics due to a change in the rigidity of the elastic filling of the machine depending on the fabric, to reduce the load on the movable rock at the time of shedding and surf, and

0 also reduce the oscillations of the moving rock and the uneven tension of the warp threads in the machine operation cycle.
