SU575389A1 - Web spreader for a circular knitting machine - Google Patents

Description

This invention relates to the field of knitwear. A wide spreading angle of the coolings is known - a tiller containing a straightening device and the web guides located beneath it in the sting of the shaft of the machine vel of the machine. The disadvantage of such a width is that during the development of the compressors of the thrusts, for example, with the main and weft threads, folds are formed on the web due to the unevenness of its stretching along the perimeter. The purpose of the invention is to ensure uniformity of the cladding of the fabric with the main and weft yarns. This is achieved in that the straightening device is made in the form of two pairs of arcs together constituting an ellipse, while the arcs of one pair are spring-loaded in the direction of the epps axis and the arcs of the other pair in the direction of the major axis of the ellipse. FIG. 1 shows a machine for the production of gkanev halls, a common fork in FIG. 2 - a tenor, a general view; in fig. 3 section A-A of FIG. 2. Kruglov zalnaya machine for the production of woven knitted cloths (Fig. 1) consists of the core 1, on which the main drive 2, the mechanism 3 in the stand and the tables are fixed: the bottom 4, the middle 5 and the top 6. On the last one, the spool 7 is fixed with reels for weft and | loop forming threads and elements for guiding the threads and signaling their breaking or tightening, as well as devices in 8 for feeding the warp threads. In the lower part of the core there are a pull-out mechanism 9 and a knurling mechanism 10 of the finished one. The spreader 11 is located between the mechanism in the underside and the shafts of the mechanism of the retention and is held on the machine by the web 12. One of the straightening apices of the shirtivl is a rigid round X 13 with rods 14 and 15 fixed with the possibility of moving in; The frame 16 of the spreader with the help of nuts 17 and 18. The frame (fitting 2 and fig. 3) is a crosspiece consisting of pipe 19 with welded

to it with cross-pieces 20 and 21. Each kz of directors 22 and 23 of the priesthood is made in the form of a bent special. Thus, the rod is fixed to one end at one end of the sleeve 24 serving to feed the web into the sting of the shafts of the pulling mechanism, the end of the guide ends with the sleeve 2Ss which can slide along the core pipe and be fixed on it with a stop screw 26. Arcs 37 and 28e of which guides 29 and 30 can be moved, in the pipe of the skeleton with subdirectional prkin 31 and 32 abutting on their ends and two large arcs 33 and 34 each having two guides and 37.38. LastN1SH can move in transverse, ON 21, Tzsgowa 16 under the action of Hse and S5s36 and 37-, 38, 38 springs 39 and 40, which abut against -Tosers. and 40j, in order to avoid arcs distortions, springs S3 and 34 should be the same. Small arcs 27,, 28 and large 38534 together form an ellipse.

In order for the handler to create a constant tension on the canvas along the perm of the ellipse, it is necessary to choose the spring force, gakr to press on the larger axis of the ellipse of the total pressure of the arc that runs along the contour of each of the arc 27 and. 28s was equal to the force of the springs 31 and 32 (and the projection onto the small axis of the ellipse C5M of the mark pressure, acting along the contour of a large arc 33 and 34 "of the force of the springs 39 and 40" This condition is satisfied if the force of the springs 31 and 39 (32 and 40) is equal to the slope of the angle of inclination of the small and large AJT at the junction point to the side of the horizontal ellipse,

The guides 2-2 and 23 of the sheet. Before the start of work are set in the desired position depending on the properties of the sheet (density, elasticity of shrinkage on the machine, and fit this position with screws 26).

When the mask is working, the ring 13 equalizes CCOD115 to occur on the gently sloping 12j e needle cylinder, and the arcs 27 ,, SSj 33 -and 34 evenly distribute the tension along the web perimeter, which excludes the possibility of the appearance of the folds on the canvas and their distribution in me- Canisma in low. If in the process of work, the machine perimeter of the web for any

the value is measured. Under the influence of the springs, dzti automatically move and take up a new position, which again ensures uniform tension of the web, in such a way that the wiper is self-destructing

poured in. The elimination of manual setup operations, spreading, facilitates its maintenance and improves the efficiency of operations. In general, the construction of the spreader allows for melting

the web roll from the cylindrical shape in the needle cylinder to the flat shape, acquired by the cloth in the shafts of the pulling mechanism, to reduce the transfer of essential elements.
