SU427518A3 - DEVICE FOR PRODUCING COMPONENT WRINK YARN - Google Patents

Description

The invention relates to devices for producing on a ring spinning machine a component twisted yarn consisting of two or more wool fibers.

The prior art device comprises an exhaust device for separately feeding components to the point of their connection and a twisting mechanism for their simultaneous twisting.

In order to obtain shaped twisted yarn with a periodically varying number of turns along the length of the thread and improve the structure of the yarn in the proposed device, a device for cycling the point of connection of the components along the axis of the yarn produced is installed between the stretcher device and the twisting mechanism.

The fixture can be made in the form of a tube connected to a pneumatic suction with a longitudinal goal for a yarn at the end, which is led into an oscillatory movement.

According to another embodiment of the invention, the fixture may be two rods, guiding the yarn and making a return-received movement towards each other and perpendicular to the axis of the yarn produced.

FIG. 1 shows schematically a device by means of which the effect of yarn formation is obtained with a periodically varying number of twists of twists

components; in fig. 2 - the same, front view; in fig. 3 is a section along the / 1-L in FIG. 2; in fig. 4 — fixture tube for moving the point of connection of the yarn components; in fig. 5 is a section along BB in FIG. 2; in fig. 6 shows an embodiment of the device; in fig. 7 - component twisted yarn.

Component torsional strand is formed when two components 5 and 4 are exhausted from exhaust 1 n 2 exhaust devices and their joint twisting on one spindle.

In order to obtain a yarn structure with a periodically changing number of twists, the device has a device 5 for cyclically moving the point of connection of the components (point y) along the axis of the yarn 6 produced to point X and vice versa, as a result of which periodically yarn and yarn are formed then with a large, then with a smaller number of turns twist. At this time, in section I, where the degree of twist is high, the degree of twist of its individual components 3 n 4 is low, and vice versa, in section II, the degree of twist of the yarn is low, and of individual components is high.

The device comprises a series of exhaust devices 7 and 8, the exhaust pairs of which feed the yarn components to a device for mixing the component connection point along the axis of the yarn produced. It is installed between the exhaust prioor and the torsion mechanism 9. The device is designed as a tube 10 attached to the pump outpump mounted on the pump shaft of the shaft 11 and vibrated movement of the cam mechanism 12 from the cam 13. The cam is driven by a chain gear 14 from the gear wheels 5 mounted on the drive shaft of 16 corrugated cylinders 17 exhaust devices. The outer end of the tube 10 has a slot 18 for receiving yarn.

Separate plates 19 are used to isolate each device on the machine, which also serve to trap the end of the component during a break.

According to an embodiment of the device, the device for moving the connection point can be made in the form of two guide components of the nuts 20 and 21, reciprocating towards each other and perpendicular to the axis of the yarn produced using gears 22 and 23. The bars are provided with fingers 24 and 25 interacting with components moving from exhaust devices. In this case, the suction pipe 26 is fixedly mounted.

The components supplied by the exhaust vapors of the exhaust devices are fed separately into the slot of the tube 10, where they are connected. When the tube moves from the junction point y to the point X, the yarn components get a periodically varying number of twists. Depending on the periodicity of change of the twist triangle and its dimensions, a different structure is obtained. Next, the yarn is fed through the thread guide 27 to the slider 28, where it is twisted by the combined action of the slider and the spindle 29 of the twisting mechanism and wound into the package 30.
