RU2309208C1 - Method for forming of creases on knitted articles - Google Patents

Abstract

FIELD: textile industry, in particular, manufacture of textile articles.

SUBSTANCE: method of forming creases on knitted articles made from single or double cloth involves knitting article up to portion where creases should be formed; forming creases of random depth, with each second stitch being transferred onto adjacent stitch followed by knitting-through of both stitches before crease forming procedure; forming creases by sequential shifting of needle case and successively connecting paired stitches making creases; when total shift reaches maximum possible value, transferring all stitches of cloth onto single needle case and moving needle case to initial position; providing reverse transfer of transferred stitches and continuing crease forming procedure. Method allows belt articles as well as shoulder articles to be produced, said articles being made without necessity of additional sewing crease forming procedures.

EFFECT: increased efficiency of method, wider range of articles produced by method, and improved quality of articles.

Description

The invention relates to a technology for knitwear production and relates to a method for knitting knitted products with folds.

A known method of manufacturing knitted products with folds by their formation during the development of incomplete knitwear due to the absence of some looped columns in its structure [1]. This method does not allow to obtain knitted products with folds in a regular way in the knitting process and requires additional costs associated with the use of auxiliary sewing operations.

Also known is a method of generating a byte fold on a flat knitting machine [2], in which the edge of the fold portion located between its two extreme layers is closed, thereby making it possible to shift the needle bar to obtain a fold. The disadvantage of this method is the dependence of the depth of the fold on the maximum possible shift of the needle bar and, as a result, the limitation on the value of the depth of the fold.

EFFECT: obtaining folds of arbitrary depth in the process of knitting a product part.

The technical result consists in the development of a method for knitting a knitted product with folds of a single or double fabric on a two-loop flat knitting machine. The method consists in knitting the product to the fold formation site, and then performing the formation of folds of arbitrary depth, moreover, before starting the formation of folds, the loops are disassembled by transferring each second loop to the next one with subsequent knitting and sequential formation of folds due to the successive shift of the needle bar and the alternate connection pairs of loops forming a fold, and when the accumulated total shift is close in value to the maximum possible, transfer all the loops of the fabric on one needle bar and the return of the shifted needle bar to its original position, then follows the reverse transfer of the transferred loops and the continued formation of the folds.

The proposed method consists in the fact that the knitted fabric, which is the actual part of the product, is knitted on one or two flat needle knitting needles of the flat knitting machine or their combination to the area where the folds should be located, then all the loops of the fabric are transferred to one of the needle beds . Based on the given depth of the folds, the width of the web necessary for their formation is determined, and a fold fold line is drawn (Fig. 1, needles 13, 15) on the front side based on the fact that the fold consists of three loop layers formed from the web section, and a fold line separates one of the layers facing the front of the part from the other two. Before the formation of folds, the loops are disassembled by transferring each second loop to the adjacent one (Fig. 1, row 2, needles 8, 12, 18, 22, etc.) with their subsequent knitting (Fig. 1, row 4, needles 9 , 13, 15, 19, 21, etc.) and the sequential formation of folds due to the sequential shift of one of the needle beds and alternately connecting the pairs of loops forming each fold by transferring them from one needle bar to another (Fig. 1, row 6, needle 15; row 7, needle 17). With the accumulation of the total shift, close in value to the maximum possible, all the loops of the fabric are transferred to one needle bar and the shifted needle bar is returned to its original position (Fig. 1, row 8, needles 23, 27, 31, 35), then the reverse transfer of the transferred loops (figure 1, row 9, needles 23, 27, 31, 35) and the continuation of the formation of folds (figure 1, row 10, needle 23), which ensures the formation of folds of arbitrary depth.

The drawing shows a graphical record of the formation of folds.

After the sequential formation of all the folds, then the remaining part of the product is knitted with a single or double weave or a combination thereof (Fig. 1, row 12).

Using the described method, it is possible to produce both waist and shoulder products with fold elements located in different parts of the parts that do not require additional sewing operations to form folds.
