Description

one

The invention relates to the field of textile industry.

The weft yarn plotter is known to the pharynx and to the edge of the fabric, designed to work on a weaving stack with a fixed weft reserve and a fixed reed, which includes a housing carrying a free-flowing disk, an entrance to the opening corner of the weft yarn, eyelets for guiding the thread and drive element for insertion into the shed.

In its movement in the throat, this plotter rests on a fixed reed, which causes its premature wear.

The iB of the proposed plotter for improving wear resistance of the housing is provided with rollers and resting on a fixed reed and means for clamping a piercing weft yarn made in the form of an elastic element equipped with a hemispherical protrusion inserted into one of the lugs and controlled by a rotary feeder hinged on case.

FIG. 1 shows a weft yarn plotter (the upper part of the body is removed and indicated by a thin dashed line); in fig. 2 plotter, general view; in fig. 3 is a view along arrow L in FIG. one; in fig. 4 - position of the plotter before entering the pharynx, top view; in fig. 5 - position of the plotter in the throat;

in fig. 6 is a section along BB in FIG. five; in fig. 7 - position of the plotter at the beginning of the exit from the pharynx.

The plier / weft yarn comprises a body consisting of a support plate 2, a side vertical wall 3 and an upper part 4 in which eyelets 5 E 6 are made to guide the weft yarn 7.

Between the plate 2 and the upper part 4 of the housing, there is a vertical axis 8 attached to the part 4 by a screw 9. On this axis there is a freely rotating disk 10 that protrudes from the housing beyond the supporting plate 2. Near the disk W there are protruding from the housing through slots 11 and 12 in the wall 3, the rollers 13 and 14 freely rotating around the axes 15 and 16. The axes are placed in the supports 17 and 18 fixed with screws 19 on the vertical wall 3 of the housing.

The front end 20 of the support plate 2 is bent upwards at the location 21 and has an eye 22. Located in the plane 23 of the plate. On the case of the plotter, a yarn thread guide 24 of a weft thread having 25 eyes 26 at its end is hingedly attached. A resilient element 27 connected at the end 28 directed downward with a hemispherical protrusion 29 is connected to the yarn feeder. The thread guide 24 together with the elastic element 27 rotates about axis 30 rigidly connected to the plate 2, and

Both parts (yarn feeder 24 and element 27) are fixed on axis 30 with nuts 31 and 32 (see FIG. 3). The protrusion 29 of the elastic element periodically enters the eyelet 22 and clamps the weft thread passing through it.

The rear end 33 of the plate 2 has a series of holes 34-37 for connecting the plotter body to the drive element 38, made in the form of a rapier, for informing the plotter of reciprocating motion in the throat. The drive is installed in such a way that the body of the plotter does not come into contact with the warp threads during movement in the open shed.

During operation, when the plotter moves to lay in the shed 39 of the next weft thread 40 (see Fig. 4) unwound from a fixed weft reserve, the plotter end 25 hits the stop 41 located at the edge 42 of the fabric 43, as a result of which the yarn feeder 24 rotates about the axis 30 and informs the elastic element 27 of the rotational motion. In this case, its hemispherical protrusion 29 enters into the bore 22 on the plane 23 and clamps the weft thread 40, which passes through this eyelet. At this time, the throat changes, the previously laid thread 7 is clamped by the warp threads and the cutting elements 44 and 45 are cut off.

During the further run of the plotter to the inside of the shed 39 for passing the weft thread 40, the rollers 13 and 14 are in contact with the fixed reed 46. A simultaneously rotating disk 10 rolls the inserted thread 7 onto the opus 47 of the fabric 43 produced, and the weft surf occurs under a pressure equal to and the opposite pressure of the rollers on the reed; the disk 10 rotates freely.

After completion by the runner

through the pharynx, the end 48 of the weft thread 40 enters the clip 49, located at the edge 50 of the fabric 43. At the beginning of the reverse movement of the mouth piece, the weft thread 40 rotates the feeder 24, while the hemispherical protrusion 29 comes out of the thread 22, the weft thread 40 is released from the clip its protrusion 29. With further movement, the yarn feeder emerges from the pharynx, laying the weft thread 40, the end of which is located in the clamp 49, along the lower 47 of the fabric. During the reverse movement of the plotter into the throat and the pre-change, the throat 40 is trimmed with cutting elements 44 E 45 and is nailed with a rotating disk 10 to the lower part of the fabric.

Further, the cycle of laying of weft threads in the throat and their subsequent surfing to the edge of the produced tissue continues in the same order.

Subject invention

A weft yarn plier in the throat and surf it to the fabric weave on a loom with a fixed weft reserve and a fixed reed, comprising a housing carrying a freely rotating disk entering the shed angle for the weft yarn, an area for guiding the thread and a drive element for insertion

0 to the pharynx, characterized in that, in order to increase wear resistance, the housing is provided with rollers supported during the movement of the sealer inside the pharynx to the fixed reed, and means for clamping the weft yarn made in the form of an elastic element equipped with a hemispherical protrusion one of the sliders and a controlled rotatable yarn feeder hinged to the body.
