Description

one

The invention relates to weaving and relates to the design of the mechanism for selecting the warp yarns to the knots of the damming machine.

A known mechanism for selecting the warp threads to the nodes of a die machine, containing plates with protrusions located between the price tubes and the tensioner mounted above the plates on the pump, is a lever.

In the known mechanism when swinging and reciprocating the price tubes moving the base, the threads lie on the plates, bend over and slide along them. This leads to stretching of the filaments and the occurrence of permanent deformation. In addition, when picking up the finished, glued or glued threads, having gone over the ledge and continuing to slide along the plates, the threads are not always separated and the selection is made from several attempts.

The purpose of the invention is to improve the quality of the selection of threads.

For this purpose, the plates are mounted on the swing axis and spring-loaded, while the protrusions of the plates are made along the hooks of the beaks, with the pointed part facing the tensioner.

The drawing shows the described mechanism for the selection of warp threads.

The mechanism contains plates 1 with protrusions 2 located between the price tubes 3 and tensioner 4. Plates 1 are mounted on the swing axis 5 and spring-loaded 6. The lips of the 2 plates are made in the manner of beaks facing the pointed part 4. mounted above the plates 1 on the lever 7, mounted on the axis 8 and the carrier roller 9, interacting with the cam 10. The cam 10 is located on the shaft 11 of the nodes of the dummy machine.

Hummer 12 serves to restrict the movement of the projections 2 towards the base.

The selection of threads is carried out as follows.

The warp threads, moved by the price tubes 3, move progressively relative to the plate 1, without touching them. Pressing the tabs all threads except the last overcome the resistance of the spring 6 and deflect the tabs, jumping over them. In this case, the plates are rotated around the axis 5, and the threads move for a certain distance, without touching the plates. By the beginning of the next selection, the plates are returned to their original position by the action of the spring. If the last extreme thread is glued together with a dressing with a previous thread, then it moves along with the base. The spring is adjusted so that the bonding force of the glued threads

less force of spring tension; therefore, the extreme thread, reaching the protrusion, does not cross over the protrusion, but is delayed, separated from the base and transmitted by the tensioner lc. a device for transmitting it to the nodes of the hallway machine.

If, when filling the base into the clamps, the yarn is fastened, then the base with the crossed threads moves without touching the plates, but only touches the protrusions, and the crossed thread easily separates from the base.
