SU68768A1 - Twisting-winding mechanism of multiple twist - Google Patents

Description

The twist-and-winding mechanisms of multiple twist are known, in which the torsional organ is made in the form of two rings rotating in different directions around the diametral axis of these rings, coinciding with the axis receiving the twisted yarn string.

The outer ring in such mechanisms provides double twisting of the thread passing through the rings.

 The proposed mechanism differs from the known ones in that the inner ring carrying out the third twist of the thread is used as a guide for the reciprocating yarn guide forcedly moving along it, folding the twisted thread along the spool.

FIG. 1 is given a longitudinal section of the mechanism; in fig. 2 - the same, cross section; in fig. 3 - a detail of the mechanism, side view.

The mechanism is made in the form of an outer ring 1, which provides a double twist of the thread that envelopes the ring during the semicircle, and an inner ring 2, which performs the third twist of the thread. Ring 2 is concentric to ring 1, but rotates in the opposite direction.

The diametrical axis around which the rings rotate coincides with the axis of the pin 3, which receives the twisted thread.

The inner ring is composed of two concentric hoops, in the gap between which, symmetrically to the middle plane of both hoops, two rings 4 are placed freely. They form a yarn feeder performing a cross-folding of the twisted thread along the spool 3. On the outer edges of the rings 4 there are hooks 5 in the form grooves for the thread.

The inner edge of each ring 4 has a ring gear that interacts with the drive bristle 6 when this ring is pressed against the gear by the tension of the winding thread.

To drive all parts of the mechanism, a block 8 is suspended on a hollow bushing 7, in the cavity of which two Gears 9 are placed, rolling N 68768-2 -

The outer crown gears of this sleeve are provided. The axis of one of the gears is provided with a gear for rotating the inner ring 2 in the direction opposite to the outer ring L connected to block 8, and the axis of gear 9 is two gears, one of which is designed to transfer the spindle with springs 10; 3, and the other 12 - gear 6, alternately vimosodeystvuyuschey with a ring gear of one of the rings 4.

The lower end of the spool 3 rests on the spring center 13.

The thread 14 enters the channel of the sleeve 7, leaves it through the side opening below the block 8, bends around the outside half of the circumference of the ring 1, receiving a double torsion, passes through the eye of the center 13 into the catch or recess of the corresponding ring 4 of the yarn feeder and, having obtained the third twist, winds on the spool 5.
