SU1300049A1 - Method of starting the first course of weft-knitting fabric with transverse-longitudinal weft threads in circular-knitting machine - Google Patents

Abstract

The invention relates to knitwear production, in particular, to methods of earning the first p and cool knitwear with longitudinal-transverse weft and allows to increase the productivity and uniformity of the looped hem structure. The method of engaging the weft-base knit is that the needle threads are threaded with the main threads, between which the ground threads laid under their hooks are needled, and the weft threads are laid on the loops, which are pulled from the needles by the main threads. Moreover, the basics of the loops of the first row impose a weft thread of increased density linearity or the first row of loops are caused by increased density or from the strands with a rough surface. The method is carried out on a circular die machine. As a result of pulling the loops towards the center of the machine by means of the main threads, gathering them into a bundle and pulling them in radial direction, the uniformity of the looped structure of the edge increases. 4 il.

Description

The invention relates to knitwear production, in particular to the development of weft-weft knitwear.

The purpose of the invention is to increase the productivity and uniformity of the looped edge structure.

FIG. 1 shows a diagram of the process of looping the first row of knitwear; in fig. 2 - the beginning of the process of looping the second row of knitwear; in fig. 3 is a kinematic diagram of a circular machine; in fig. 4 - bed of the needle cylinder.

The process of earnings is carried out as follows.

Between the needles 1 of the needle cylinder 2, the main threads 3 are threaded, between which the needles 1 are fed by the ground threads 4 laid under their hooks (Fig. 1). On the loops 5, knitted with needles 1 of this thread, weft threads 6 are applied (Fig. 2), with the first row of maximum density, i.e. the smallest possible length (not shown). Due to the fact that loops 5 are short lengths, some loops (5a), which are located on the needles, may not be dropped from the tongues of the needles during their imprisonment. In this case, they are reset manually. This operation is performed when the machine is started up manually or at low speed from starting the engine. After making a complete revolution in the hall systems around the cylinder or the cylinder around the hall systems, density is increased in accordance with the necessary requirements.

. In this case, the main threads are pulled away by hand into the depth of the cylinder (according to arrow A). Due to the fact that the first row of loops is produced by a low density, this row and weft yarns reliably attach to the main threads, which, when manually tensioned, retract the loop from the needles set in motion by the second, etc. systems.

It is possible to provide the necessary fastening of the loops to the main threads by laying on the loops of the first row of weft threads of a higher linear density, as well as by developing the first row of loops of the threads with a rough surface.

The method is carried out on a circular die machine (Fig. 3), which contains a needle cylinder 2, clamped

with the bed 7, and the locking system I, driven by the lead 9, mounted on the gear 10, kinematically connected with the drive of the machine (not shown in FIG. 3). The bed 7 (Fig. 4) is filled into the shape of a hollow cylinder, the lateral surface of which contains through. Holes (B) of an oval shape, the dimensions of which allow to place a hand in them, for example 200x300 mm.

The earning of the first row of linen and its knowledge on the machine is carried out as follows.

The beginnings of the main threads 4, located between the needles 1, are clamped between the fingers of a hand placed in the opening B of the bed frame 7, made in the shape of a hollow cylinder, and move away from the needles downward (along arrow A in Fig. 2) so that it is possible to fasten them (bundle) into one or more wiring harnesses. During the making of the first row under the hooks of the needles 1, a ground thread 4 is fed, which is interleaved between the main threads 3 in loops 5 (fig. O on which are applied) weaved thread 6. and the car is turned on by the electric motor.

Since the needle loops are not retracted. loops, previously laid out, and the main threads, the shape of the loops is statically balanced and, therefore, during the relaxation of the threads of the loops, the loop does not occur and the edges of the web do not suffer from heterogeneity of the structure.
