The invention relates to textile industry and is intended for the manufacture of fancy yarns on spinning machines.

A device for producing fancy yarns on a spinning machine is known, comprising a torsion bar and a pair of rollers with support trunnions / for feeding rovings with a variable speed to the outlet. Пару. A pair of exhaust device with an intermediate pair [1].

However, the location above the exhaust device of a pair of rollers with their bearings and drive, complicates the design and maintenance of the machine. .

The aim of the invention is to simplify the design and maintenance.

This target is in the device. for producing fancy yarn on a spinning machine containing a torsion body and a pair of rollers with support pins for feeding rovings with a variable speed to the exhaust pair of the exhaust device with an intermediate parde, is achieved by the fact that the drive shaft. pairs for feeding rovings made with an eccentric axis of rotation has guides for the free movement of its journal and is pressed against the pressure roller of the supply or intermediate pair of the exhaust device.

A pair of valines ’for feeding the roving is located on the load lever of the exhaust device.

The guides are made rectilinear, and the roller is mounted to rotate relative to its journal.

The drawing shows a General diagram of the device.

The device comprises a pair of rollers 2 and 3 with / on the trunnions located on the load lever 1 of the exhaust device for supplying rovings 4 with variable speed to the exhaust pair 5 of the exhaust device. The drive roller 3 is made with an eccentric axis of rotation 6. The roller bearing pin is located in straight guides made on the lever 1. The roller 3 is pressed against the pressure roller of the intermediate 7 or supplying 8 pairs of the exhaust device and mounted to rotate relative to its · 'axle. The roving 4 is wound off the bobbin 9 mounted on the roving frame 10. The main roving 11 is wound off “with the bobbin 12 located on the same roving frame 10, by” 956650 steps into the supply pair 8 of the exhaust device and in the form of a sliver 13 evenly leaves its outlet pair 5. Rovnitsa-4, designed for the formation of shaped effects, from bobbin 9 is fed into the clamp, formed by a pair of rollers / 2 and 3, from which it is guided through tray 14 to the exhaust pair 5. The rovings 4 are fed at a variable speed in accordance with with a change in the rotational speed roller 3 due to its eccentric landing on its axis, movably mounted ¹ on the lever of the exhaust device.

. The distance between the rollers 2 and 3, 15., Supplying the roving 4, intended for the formation of shaped effects, and the exhaust pair 5 is greater than the average length of the fibers of the roving 4, therefore its bundles are periodically torn off due to the difference in speed of the pair of rollers and the exhaust pairs 5, Variation in the feed rate of the roving 5 contributes to a variety of tearing off, fiber bundles from it, & · 25 as well as the distance between them, which eliminates the possibility of a moire effect in products from such yarn. Bundles of fibers torn from rovings 5 at the exit of exhaust pair 5, jq * are twisted with a sliver using a torsion body. 13 derived from. the main roving 11, forming a fancy yarn.

By changing the eccentricity of the roller 3, it is possible, accordingly, to modify the structure of the shaped yarn.

The advantage of the proposed device is the simplicity of its design by eliminating the elements of the Drive roller 3, as well as universal. ‘Grease, since without auxiliary-.

A pair of rollers, an exhaust device can be used to produce ordinary yarn.

The effectiveness of the proposed device is that with its help it is possible to diversify the external structure of the produced yarn without additional processing processes and facilitate the maintenance of the machine.

Claims (3)

Claim 1. A device for producing fancy yarn on a spinning machine, comprising a torsion body and a pair of rollers with support pins for feeding the rovings with variable speed to the exhaust pair of the exhaust device with an intermediate pair, characterized in that, in order to simplify the design and maintenance, the drive roller of the pair for The roving supply is made with an eccentric axis of rotation, has guides for free movement of its pin and is pressed against the pressure roller of the supply or intermediate pair of the exhaust device ” 2. The device according to claim 1, t and h (.. and further with the fact that a pair of rollers for feeding rovings is placed on the load lever of the exhaust device. 3. The device according to claim 1, with the proviso that the guides are straightforward and the roller is mounted rotatably relative to its pin.
