(54) KNITTING MECHANISM

The invention relates to a knit machine industry, in particular to single-circular circular hall masters.

The known mechanisms in the draw of single-fingering circular machines do not ensure uniform web tension along the perimeter of the cylinder. The main reason for the non-linear tension of the blade around the perimeter of the cylinder is that the chin of the platinum extends beyond the limits of the platinum corolla. Thus, for example, in the zone of maximum chin protrusion of platinum beyond the limits of the platinum corolla, the tension of the web increases by 25-35%.

The closest in technical essence is the mechanism in an under-known round-hole filling machine consisting of a cylinder / block with wedges i rings with platinum locks, a ring with yarn feeders, a platinum ring,

platinum corolla, tongue needles and platinum A disadvantage of the known mechanism in the underlay is the exit in the process of looping platin chins beyond the platinum corolla, which causes the uneven tension of the knitted fabric and has a significant effect on the quality of the knitted fabric produced and the non-uniformity of the loop structure. In addition, the release of platinum beyond the platinum corolla leads to the appearance of a tilting moment, which causes additional loads on the pays well, which leads to increased wear of the working surfaces of the platinum locks,

to the platinum corolla and platinum ring ..

The purpose of the invention is to improve the quality of knitted fabric at the expense of excluding additional local

15 tension in the platinum zone.

The goal is achieved by the fact that in the mechanism in the drill, containing a needle cylinder, tongue needles, platinum whip and platinum, butt end

The chin of the platinum is shaped according to the shape of the cross section of the platinum corolla, while the chin length is such that when platinum is in position at the moment of pulling, the end of the chin is flush with the platinum corolla.

FIG. 1 shows the mechanism in the underside of a single-bottom circular machine, section, and FIG. 2 - mutual

30 the position of the platinum and platinum corolla with the maximum extension of the platinum p to the center of the needle cylinder in the known design of the mechanism in under; in fig. 3 - the moment of maximum advancement of platinum of the proposed mechanism in the low.

The mechanism in the thread consists of a needle cylinder 1, in the slot of which the tongue needle 2 is located. A platinum rim 3 and a platinum ring 4 are rigidly attached to the cylinder. Platinum 5 is installed in the groove of the platinum rim and platinum ring. looping. An NSSch-platinum ring fixedly mounted ring b, to the surface of which is fastened a platinum lock 7, informing the movement of the platinum during operation of the machine. The ring of thread-guides 8 is rigidly connected with the ring b to the thread-guides 9 fixed to it. On the outer side of the axis of rotation of the cylinder, a block of 10 locks is mounted with a stand 11 with a control plate 12 fixed firmly on it and 13 wedges that impart movement machine operation. An adjusting screw 14, used to adjust the raft, is installed in the lock block;

The mechanism in the undercut, as well as the previously known mechanisms, is intended for performing the process of looping. The principle of its operation is as follows. When the cylinder 1 rotates, the tongue needles 2 make a reciprocating movement, which is communicated to them by the snout 12 and enclosing 13 wedges, rigidly fixed on the rack 11 of the block 10 of the locks.

; Together with the cylinder, the platinum ring 4 and the platinum halo 3 rotate, in the grooves of which platinum 5 are located making radial motion, imparted by platinum locks 7 fixed on the ring 6. Needles being in the upper position, passing by the yarn feeder 9 fixedly mounted on the ring 8, a thread is captured (not shown), its wire to the zone in the undercoat. Platinum 5, which is maximally advanced at this moment to the center of the machine, protrudes the old loops only with its mouths, without having an effect {additional tension by picking

on the fabric, which eliminates the contact of the platinum with the fabric in the process in the low and enhances the quality of knitted pblotna, reducing

This wear of the parts of the mechanism in no.

This technical solution makes it possible to increase the reliability of the mechanism operation, improve the quality of the three-coiling fabric and reduce the consumption

electricity by about 12%.
