FIELD OF THE INVENTION The invention relates to the textile industry and relates to devices for arranging chemical yarns subjected to oiling.

A pitcher is known, advantageously to the mechanisms of the layout of chemical filaments, consisting of two plates forming a channel for the passage of the filament.

The known yarn feeder removes the lubricant from the thread by the edges of its working part, thereby disrupting the uniformity of its distribution in the thread, and sprays the lubricant in space, complicating the operation of the mechanisms located nearby.

In order to improve the quality of the displayed yarn, the passage channel of the yarn has the shape of two trapeziums connected by smaller bases in a transverse section. In order to reduce the overturning min. Of the yarn feeder, when laying out the plates, they have shaped cuts.

FIG. 1 depicts the described pitcher installed in the layout mechanism, axon-metric projection; in fig. 2 - yarn feeder in cross section.

In the slide mechanism 1 of the pickup 2, the yarn feeder is rigidly fixed, consisting of two thin-walled plates 3. Faced to one another, the plates 3 form a channel

for the passage of nitp 4, having in cross-section the shape of two trapezoids connected by smaller bases lp. Rounds are formed in the upper part of the channel along its entire length. The plates 3 are made in the form of a hard box section of a thin-sheet material strengthened, for example, by chrome plating. To reduce the tilting moment of the folding system, the center of mass

a slider with a yarn feeder is as close as possible to the axis of symmetry of the friction surfaces by forming shaped cuts on the horizontal surfaces of the plates.

In the course of the layout, the oiled 4 passes through the microcamera 5 of the channel formed by the plates 3, with which the thread is in contact only in its middle part. The channel gap 5 is adjusted depending on the thickness of the unfolded thread 4. Excess oil consumption. applied to the thread, is collected in the microcamera 5 - and is evenly redistributed to the thread 4 by dwelling or pressing out of the lip as it passes through the yarn feeder. The trapezigvidp form of the microcamera 5 ensures the holding of lubricants in it, facilitating the molecular adhesion forces of the wetted surfaces of the yarn feeder channel.
