Abstract

FIELD: textile industry.

SUBSTANCE: method is as follows: all loops of the left sleeve are transferred to the front needle bar with regard to body loops transferred to the rear needle bar by a number of needle pitches required for horizontal joining of body and sleeve. After that, body and sleeve loops are joined by simultaneous transfer and knitting of body and sleeve loops and sequential closing of knitted loops due to their transfer to adjacent loops of the same line. Furthermore, all loops in joined with body sleeve are transferred to the rear needle bar. Meanwhile, right sleeve loops are located on the front needle bar and body and sleeve are joined similarly to the left sleeve. Resulted joined detail consisting of body and sleeves is folded from edges moving to forepart centre due to sequential transfer of end sleeve loops to needle bar containing item front ends.

EFFECT: strong horizontal joint of sleeves and body details to be not distorted during wearing of hose-type knitted items with ends along lengthwise openings.

Description

The invention relates to a technology for knitwear production, in particular, to a method for producing whole knitted knitwear with sleeves, and can be used for the manufacture of household, sports and technical products.

There is a known method of knitting a knitted product [1], in which the shelf and back are knitted from different threads and after knitting a certain number of stitch columns of the mill, the last looped row of sleeves is transferred to the stitches of the mill and knitted with them. The disadvantage of this method is that this invention is based on the connection of the sleeve and the mill in the vertical direction, and the looped rows of the shelves and backs can be connected only by different thread guides.

A known method of knitting a tubular knitted product [2]. The double side of the product is knitted between the back and shelf layers through the use of four flat needle knitting four-loop machines. This method assumes the presence of four needle beds on a flat knitting machine.

A similar method is known for knitting on a flat knitting machine a knitted fabric with edges along a longitudinal hole that are superimposed on one another in a worn product [3]. The right and left edges are knitted on the same needle bed next to each other, and a certain number of looped columns on the edges of the right and left halves of the hole are knitted on the opposite needle bar. The disadvantage of this method is that they produce a product with a longitudinal hole in which the connection of the sleeves with the mill is due to the transfer and then knitting of two loops of the armhole with two loops of okata, in connection with which, during operation, tension of the threads and their constriction, due to which the structure is deformed.

The technical result is to obtain a horizontal connection of the details of the sleeves and the mill of the whole knitted product with the edges along the longitudinal holes with the connection of the parts by a horizontal seam on a flat knitting machine, which provides a more durable connection of the parts of the product that is not deformed during operation.

The technical result of the method of knitting a knitted product on a flat knitting double-loop machine is achieved by the fact that the parts of the product, made on the basis of single weaving webs, with edges along the longitudinal holes of the mill, which are worn on the product overlap each other, knit without connecting with each other, while knitting on both needle cases in the form of tubes of the mill and sleeves, they are connected in the process of knitting along a straight section located in the horizontal direction, for which all the loops of the left sleeve, transferred to the front needle bar, move relative to the loops of the mill transferred to the rear needle bar by the number of needle steps needed to form a horizontal seam, and then connect the loops of the mill and the left sleeve by simultaneously transferring and knitting the loops of this sleeve and the mill, and sequentially closing the knitted loops by transferring to the adjacent loop the same layer, after which all the loops of the sleeve connected to the mill are transferred to the needle bar, where the mill is located, and all the loops of the right sleeve are located are placed on another needle bar, then the loops of the right sleeve are moved relative to the loops of the mill by the number of needle steps necessary for the formation of a horizontal seam, and the parts of the mill and sleeves are connected in the same way, after which the resulting single part, consisting of the mill and sleeves, is rolled from the edges, shifting to the center of the shelf due to the sequential transfer of the extreme loops of the sleeves on the needle bar containing the edges of the front of the product.

The invention is illustrated by drawings.

Figure 1 presents the design of a knitted product, from which it is seen that the OK region is a horizontal section.

Figure 2 presents the connection diagram of parts of a knitted product with the edges along the longitudinal holes with a horizontal seam.

Figure 3-6 shows a graphical diagram of the process of horizontal connection of parts of the sleeves and the mill.

The proposed method for joining parts is performed on a double-loop flat knitting machine having two-sided selection of needles, a mechanism for shifting needle beds and a mechanism for double-sided loop transfer.

To connect the hinges of the sleeve with the hinges of the mill with a horizontal seam, it is necessary to unroll the tubing of the sleeves beforehand, displacing the side seam formed during knitting of the sleeves towards the back, and install the connecting loops of the mill and sleeves opposite each other, for which it is necessary to shift all the loop hinges relative to the loops camp.

To perform the shift of the mill parts relative to the details of the sleeves, the loops of all layers of the mill are transferred to the rear needle bar, and all layers of the sleeves are transferred to the front needle bar.

If it is necessary to connect, for example, loops: 6 s 12 , 8 s 14 , 10 s 16 of the left sleeve with the mill, the front needle bar is shifted to the right by 6 needle steps, after which the loops are transferred from needles 6, 8 and 10 to needles 12 , 14 , 16, respectively, then all the loops located on the needles 12 , 14 , 16 are knitted.

From the needle 16, the knitted loop is transferred to the needle 10, after which the front needle bar is shifted in the opposite direction by 2 needle steps. From the needle 10, the loop is transferred to the needle 14 and knit, as a result of which the loop formed on the needle 16 is “closed”.

The front needle bar makes a shift to the right by 2 needle steps and the process of transferring the loops from the needle 14 to the needle 8 is performed, the front needle bar is shifted to the left by 2 needle steps and the loop from the needle 8 is transferred to the needle 12 . Next, the process repeats and forms a horizontal connection of parts according to the type of “looping”.

After connecting the required number of loops of the left sleeve with the mill, the front needle bar is shifted to the left by 1 needle step and all the loops of the left sleeve are transferred to the rear needle bar, after which the front needle bar makes a shift of 11 needle steps and the cycle repeats in the opposite direction.

After the process of connecting the right sleeve to the mill, all the loops of the front needle bar located on top of the broaches of the loops of the rear needle bar are transferred to the front needle bar in order to separate the layers of the front and back cloths. The formed single part, consisting of the loops of the sleeves and the mill, is folded from the edges due to the sequential transfer of the extreme loops of the sleeves to the needles of the rear needle bar containing the edges of the front of the product, shifting them to the center.

Introduction to the structure of the horizontal connecting section increases the strength and reduces the extensibility of the connection area of the parts of the product.
