SU1465466A1 - Method of knitting fabric in double-cylinder flat- and circular-knitting machines - Google Patents

Description

The invention relates to the production of knitwear, in particular, to methods of performing the loop formation process.

The aim of the invention is to expand the technological capabilities and improve the quality of the web.

Fig. 1 shows the trajectories of needles and platinum in the loop formation zone of a dvukhfonturnoy planar inguing machine when woven into a fabric by interlacing an eraser 1: 1; figure 2 - section aa in figure 1; on fig.Z - section bb in fig, 1; 4 is a plan view of the interaction of the platinum with the web.

The proposed method is implemented as follows.

The loop formation zone (Fig. 1) is divided into three sections. On plot B

They carry out removal and conclusion operations, at section G — operations of laying a thread, pressing, applying, joining and smoking; in part D — operations of forming new and stretching old loops.

The needles 1 (Fig. 2, 3) of the machine are recruited with tongue needles 2, combs 3, connected to the needles 1 of both of the phonetra, recruited by fender plates A.

The cloth 5 is tensioned along the hinge columns in section D of the loop formation zone (Fig. 1) by friction caused by the interaction of the fender plates 4 with the blade 5. At the same time, the old loops 6, dropped from the needles 2, are moved along the rods of the newly crooked loops 7. also alternately placed in the throat 8

needles 1. To interact with the web 5, the fender platinum 4 (ig.4) of both of the fountains push 8 needles 1 into the jawbone and bring it into contact with the canvas 5 in the area of the first rows, counting from a number of new loops, so that it is deformed between the platinum of 4 opposing fountains. In this case, the web is stretched in width.

Locks 9, platinum A, structurally reinforced in such a way that the magnitude of the stroke of platinum 4 and the force applied to the web are adjusted, secured to the locking carriage 10.

When platinum 4 interacts with web 5, a friction force arises, directed under the sharp to the symmetry axis of the shed 8 of the needle bed 1, and the tensile forces directed along the looped rows. Under the action of the vertical component of the friction force and the stretching force of the polix 5,

new loops 7 on section D, zones in the underturn and discard the dropped loops 6.

The proposed method in the bedding fabric allows, for example, to produce flat parts of the products along a contour with a well-fixed edge and non-planar parts, such as shelves of upper clothes with undercuts, which significantly expands the technological capabilities of the equipment and reduces the waste of the raw material. cutting of products. It also allows reducing the yarn's threadability and reducing the amount of non-assorted products and waste materials when they are injected. In addition, it allows processing high-modulus, bending-rigid yarns on hall machines, as well as creates prerequisites for increasing machine productivity by reducing downtime due to thread breakage in the undercarriage zone.
