In front of the feed pair, a bar 25 is installed in the direction of the threads, with guides 26 of the surge threads 6 and 7, which is located along the feed pair with the possibility of longitudinal reciprocating movement by means of a drive. The drive of the bar contains an electric motor 27 connected by a V-belt transmission 28 with the shaft 29 mounted on the frame 30. At the end of the shaft 29 a disk 31 is fixed with an eccentrically placed roller 32 located between the stops 33 fixed on the 25 "bar 15 The thread guides 34 "are fixed at the exit of the threads from the feed pair between the spindle and the hollow spindle.

The working surface 35 of the driving cylinder 8 of the feed pair has the shape of 20 two truncated cones mated with large bases, and the working surface 36 of the pressure roller 9 has the shape of two truncated cones coupled with a smaller base. In the zone J5 The junction of the cones on the roller and the cylinder is provided with annular grooves 37 and 38 for the passage of the core yarn 5. The length of the displacement of the bar 25 in both directions is less than the length of each Chenne cone of the cylinder and the roller.

The device works as follows.

Guiding rods 39, nitenate - Residents 40 and hooks 41 of the control switch sensor are passed through different colors of the threads 5, 6 and 7, being unwound from the feeding packages. Next, the core thread 5 enters the annular grooves 37 and 38 of the cylinder 8 and the pressure roller 9 of the feed pair, mine it passes through the thread guide 34 at the speed of the exhaust shaft.

At this time, the surge threads 6 and 7 (for example, red and white) come under the elastic conical surfaces of the roller 9. Linear The feed speed of the surge threads, reported by the feed pair, is different, since at the points of their clamping between the roller and the grooved cylinder the latter diameter, and exceeds the linear speed of the exhaust pair by an amount determined by the specified shaped effect of the shaped thread 17.

At the outlet of the feed pair, the filament threads pass through the thread guides 34 and, due to the difference in speeds, form effects on the core thread 5

loops or boucle depending on the effect.

The blank of the shaped thread 42 passes through the channel of the hollow spindle 12 and is secured by the thread 15.

The workpiece 42 at the exit of the hollow spindle 12 makes one complete revolution around the reel 16, where the spin turns in the opposite direction and the final consolidation of the resulting effects occurs.

Next, the finished thread 17 is supplied to the outlet pair 10 and 11, when leaving it, the thread conductor 43 bends and is wound on the receiving package 23, driven by the winding drum 19.

The resulting shaped thread 17 has effects in the form of loops or boucle, depending on the given ratio of feed and discharge speeds. The ratio of the release rate to the rotation frequency of the hollow spindle determines the rapport of the arrangement of effects.

When the surge threads are in an unchanged position relative to the feed pair, the shaped thread has a hue or completely the color of that surge string, which has a higher surge value (linear feed rate).

Conditions for producing a de-effect. It is pleased that the total amount of surge, the surge threads must be constant (this provides a constant yarn structure), and the magnitudes of the surge (excess) components change alternately and inversely.

Smooth color change of shaped effects, i.e. the effect of degradation (from red to white and vice versa) occurs due to an alternate increase in the magnitude of the surge (the linear feed rate) of one of the surge strings and, accordingly, the same decrease in the other. This is achieved by simultaneously moving, with the aid of a strip, the surge strings 6 and 7 in the feed pair from the position in FIG. 2 to the position in FIG. 3

The process of smooth color change proceeds as follows. A direct current motor 27, tuned to a specific rotational speed, transmits a rotational movement to the disk 31 by means of a V-belt transmission 28.

When the disk 31 is rotated clockwise, the roller 32, eccentrically located at its end, presses on the stops 33 of the bar 25, carried out its longitudinal movement along the feed pair.

When depicted in FIG. In the 2 positions of the red surge thread 6 and the white surge thread 7 in the shaped thread, the red color is almost invisible and it has white color.

The bar smoothly shifts the clamping point of the red surge thread 6 to the side where the corrugated cylinder 8 has a larger diameter. In this case, the line-1 on the speed of the surge thread is inversely increased in comparison with the linear feed rate of the white surge string 7, and the color gamut

Vani rotational speed of the motor shaft and the selection of interchangeable pulleys of the V-belt transmission 28.

The proposed device allows producing an original shaped thread, in which the color of shaped effects smoothly changes from one scale to another, in appearance resembling yarn, obtained by chemical methods of dyeing, which greatly expands the assortment of shaped thread. The change of color range can be in the range from 1 m to 10 km.
