SU1240365A3 - Method of manufacturing tights or similar artices on double-cylinder circular knitting machine - Google Patents

Abstract

A panty-hose product (tights) is processed on a two-needle-bar knitting machine with a continuous rotating motion so as to form two tubular product (15-17) at one and the same time with the two needle bars and with different feeds (A) or descents of yarns, whereas the panty portion is formed with a connecting zone (Cc) cut in the lengthwise direction (T); needles (11-13) of the two needle bars are activated in said connecting zone (Cc) so as to form a structure of ribbed stitching with plain (MD) and purl (MR) stitches next to each other.

Description

The invention relates to a method by which pantyhose can be obtained on a double-furrow ring.

The aim of the invention is to increase the strength of the product.

FIG. Figures 1 and 2 respectively show the needles of the cylinder and rippshaib at the time of the withdrawal of the torso part of the product; FIG. 3 and 4 - sequential position of the moving needles; / in fig. 5 - separation of two elements of the product; in fig. 6 and 7 - the position of the needles of two opposite cylinders during the formation of the torso part; in fig. 8 - part of the web when executing a looped row corresponding to the connecting zone; in Fig.9. - products at the time of inversion; Fig 10 is a portion of the product after bind; in fig. 11 is a cross section of the product during the cutting process.

FIG. 1-4 shows the needles of a cylinder and rippshaiby. The positions A1, A2 A3 and A4 designate the yarn feed areas with the extensions G1, G2, G3 and G4. Needles 5 receive the thread and form the face loops of the surface, and needles 6 receive the thread and form the back loops.

To form two semi-finished tubular products 7 and 8, simultaneously with continuous movement, they are obtained from the respective yarn supply sources A2 and A4, and the needles 5 receive a thread from the respective yarn supply sources A1 and A3. Thus, two tubular members are formed simultaneously.

To form the torso part of the product, it is necessary to connect the two specified tubing elements to each other and cut the product along the connecting zone (T in FIGS. 5 and 6), where the tubular web 7 is formed inside the tubular web 8, each of which forms - with a needle 6 or 5 of one of the needle patterns. Zone C is connecting with respect to webs 7 and 8, split by cutting, denoted T. During the formation of the torso part of the product, the connecting zone C is simultaneously performed by a group of needles 5 and 6, causing elastic, interlacing. In this case, the needles receive a thread from one supply system or from several, in a preferred embodiment, the needles receive a thread from all

feeding systems A1, .A2, A-3 and .A4 (Fig. 1-4), respectively, reflect two points in the formation of the connecting zone Cj in front of the feeding systems A1 and A2 of the cylinder and ripshaiba together with the needles,

In the position of FIG. The 1 and 2 needles pass in front of the feeding system A1, which is preset to form zone C, therefore at this moment not all the needles 5 rise and not all the needles 6 are held inside, but several feeding systems A1. Over all 5 needles under-. You only needles 5A (two pairs), then as needles 5B, and also two middle needles 5C are held in the lower position. At this moment, the needles 6A of the ripschais, which correspond to the fixed needles 5B, are also retracted. Only needles 6 receive a thread from A2 and A4 feeding systems.

The needles 5 work with the feeding systems A1 and A3 (Figs. 3 and 4), and the needles 6 with the feeding system A4.

The feed system A2 passes the needles, which are preset to form a connecting

zones Cjj, namely needles 5A, 5B, 5C and 6A, which are again selected in such a way as to form the zone of junction C (,.

When the needles are pre-installed to form a connect-. the body zone C, are in front of the feeding system A3 and A4,: the positions shown for the feeding system A1 (Figs. 1 and 2) and for the feeding system A2 (Figs. 3 and 4) are repeated.

FIG. Figures 6 and 7 show the arrangement and the production method for carrying out the invention in the case where the machine has two opposite cylinders. A9, A.10, All and A12 denote four feed systems, and G9, G10, G11 and G12 respectively are thread conductors.

The needles, 13 lower cylinders work with feed systems A9 and A11 to form, web 8, and the needles 14 of the upper cylinder work with feed systems A1O and A12 to form web 7. At the connecting zone Cp, the needles of two cylinders receive a thread from all thread-conducting systems.

To set in motion the needles 13 and 14 previously installed

To form the zone Cj ,, needle webs that have a special height can be provided.

Thus, the structure of the canvas (Fig. 8) was obtained, the looped rows of which in this zone include face and back loops, i.e. elastic interlacing, when starting from the peripheral zones designated by E, loops are formed by the threads of one web 7 together with loops of the threads forming the other web 8. In the central zone of the G, the loops may be absent, i.e. no needles rise to the conclusion. . .

SB Cc St

The cutting, indicated by stumps in the trees T, is carried out in the central zone D, by any method (by heating or using blades, etc.) on the machine.

After cutting, the products are treated as shown in FIG. 8 to achieve the position shown in FIG. 10, in which so-called lowered loops are inside the product.

In this way, in zone C, a strong connection of the product is formed; at THIS, the connective zone itself has a beautiful appearance.
