Description

This invention relates to textile machinery and can be used on shuttleless looms.

The purpose of the invention is to improve the technological design without reducing performance.

FIG. 1 shows the plotter, a general view; in fig. 2 - plotter, top view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 is a sectional view BB in FIG. one.

The plotter contains a composite case made of two symmetrical parts 1 and 2, mounted in the case of the weft yoke 3, the branches 4 of which are longitudinally located in the body cavity and have sponges 5 at their ends for clamping the weft yarn 6, Parts 1 and 2 of the case are connected along the plane 7 of the connector, located in the plane of the grip 3 by means of the dowel pin-clamping elements 8 installed in the front and tail areas of the casing 8. 9 and 10, which can be performed, for example, E as a rivet The plotter is equipped with

at least one means for fixing the housing parts 1 and 2, which is located in its tail area and is intended to prevent these parts from moving relative to each other. Said means is made in the form of a pin 11, the ends of which are inserted into recesses made in parts of the housing. The connecting element 10 and the locking device (pin) 11 are installed between the branches of the grip with a gap.

The plotter works as follows.

Under the action of an opener (not shown), the branch 4 of the gripper 3 is diluted, and the weft thread 6 is introduced into the gap formed between the jaws 5. In this case, the opening of the sponge 5 opens the weft thread under the action of the elastic forces of the branches. Further, the combat mechanism (not shown) accelerates the plotter.

The execution of the plotter’s hull with prefabs of two symmetrical parts simplifies the manufacture of the hull, and the presence in the liner

Claims (2)

A tool that prevents these parts from shifting relative to each other ensures that its performance characteristics remain at the same level. Claim 1. Plotter weft yarn to a loom, containing a composite case, fixed in the case capture weft yarn, made in the form of a clip with clamping jaws, the branches of which are longitudinally located in the cavity of the case, characterized in that, to improve the manufacturability of the design without reducing its operational characteristics, the casing is made of two symmetrical parts connected along the plane of the connector located in the catch plane, with the help of clamping elements, while the plotter is provided with at least one means of fixing the housing parts relative to each other, and the connecting-clamping element located in the tail area of the housing, and fixation means are installed between the gripping arms with a gap. 2. The plotter of claim 1. distinguishing the fact that the fixation means is made in the form of a pin, the ends of which are inserted into recesses made in the body parts. -7 mn AT one 2 Figtn 2 A-Awo8epHymo) B-B (turned) .
