DEVICE FOR PUTTING OF THE DEFINITION

ON THE BASIC TIE MACHINE

one

The invention relates to a knit machine industry.

A device for laying a weft MITI on a base of a filling machine is known, comprising a yarn thread guide reversible along the front of the needles and thread holders located in the places of its rotation behind the working needles.

The purpose of the invention is to increase the productivity of the machine. This is achieved by the fact that the yarn feeder of the proposed machine is movable but closed in the form of a crank with a tubular axis and an eye for the thread at the free end, and the thread holders are made in the form of double-shouldered figured levers pivoting in different directions.

Thread holders can serve as links to attach a thread to the main yarn.

FIG. 1 depicts the onisable machine, the cut; in fig. 2 is a perspective view of the weft yarn; in fig. 3-7 - moments of laying the weft yarn.

The device contains a weft yarn guide 3 mounted on the bed / base of the dummy machine perpendicular to the needle bed 2. The thread guide is made in the form of crank 4 with tubular axis 5 and eye 6 for the thread, moves along the front of the needles 7 in a closed circle 8 and has a balance bar 9. The rotation of the crank 4 is carried out by means of a sprocket 10, a chain // and a sprocket 12 fixed on the shaft 13. The latter through a conical pair 14, 15 is connected to the main shaft 16 of the machine.

The yarn holders 17 are located at the turning points of the weft yarn 3 behind the working needles 7, i.e., at the edges 18 of the knitwear 19, made in the form of double-arm levers turning in different directions, and serve as links for applying the weft yarn to the main yarns.

The device works as follows.

A yarn guide with an eye for yarn 3 describes a closed circular orbit in arrow A. Holders 17 rotate in arrows B and C 1/4 turn during the turn of the yarn feeder half a turn. During each looping cycle, the yarn feeder always performs a half-turn, which is ensured by transferring the elements 10, 11, to 12 in the ratio 1: 2.

The weft thread is laid on the hook-shaped part 20 of the holder 17. At this time, the loop 21 of the weft thread is applied to the knitwear 19 by the hook-shaped part 22 of the opposite holder 17.

If the yarn feeder is from the position shown in FIG. 2 is rotated to the reverse position shown in FIG. 3, then knowing

Along the circle 8, the weft thread lies on the hooked part 23 of the holder 17 of the thread.

FIG. 6, the lower holder 17 is in the transfer position of the thread, while the upper holder 17 has already taken the thread from the yarn feeder orbit. These positions are held alternately by thread holders.

Claims (2)

1. An apparatus for laying a weft yarn on a warp of a pouring machine, comprising a weft yarn thread moveable along the front of the needles, and yarn holders located at the places of its rotation behind the working needles, characterized in that, in order to increase the productivity of the machine, the yarn guide is moved in a closed circle and made in the form of a crank with a tubular axis and an eye for the thread at the free end, and Thread holders are made in the form of double-shouldered figured levers, turning in different directions. 2. An apparatus according to claim 1, characterized in that the thread holders serve as links for applying said thread to the main threads. 23 18 play 18 17  7
