SU704876A1 - Apparatus for forming tubular cop - Google Patents

Description

 ; t. ,

The invention relates to a textile industry in the field of yarn rewinding on weft winders and is intended to form tubular cobs.

A device for forming tubular cobs is known, which contains a winding head with a device for forming a cob nest / pressing carriage, a nitena guide and

nitenate resident 1.1

A disadvantage of this device is the lack of a constant tension when rewinding synthetic fibers.

The purpose of the invention is to ensure the formation of a cob from synthetic yarns. This is ensured by the fact that the device is equipped with a compensating roller and is connected to it with a two-arm lever and a damper, and at this point the thread guide is a freely mounted roller.

FIG. 1 shows the device, a general view; in fig. 2 - tubular nest of cob.

The device comprises a bobbin holder 1 for the reel being wound, spring-loaded brake discs 2, thread guides 3 and 4, guide rollers 5 and b, spindle 7, a cone 8 for forming a nest of the cob, a yarn spreader 9, a straightener 10 and a pressing carriage 11.

The roller b is freely mounted on t of the spring damper 12..

Buckle 10 serves to prevent the cone 8 from being squeezed from the cob nest and to create a cone of the correct shape: WE. .

The pressing carriage 11 provides a certain winding density. To foil the cob nest 15 of the cob, one cone 8 is used, which eliminates sintering of individual turns of the cob at a high transfer rate.

The device works as follows.

The weft thread 13 (see Fig. 1), removing it from the reel, passes through spring-loaded brake discs 2, neither the guide 3, bends around the rotating

25 guide rollers 5 and b.

Then the thread passes through the thread guide 4 and the thread spreader 9, a modern reciprocating motion, and enters the zone of forming the nest of the tubular cob.
