Description

Process and apparatus for automatically producing tubular knitwear items provided with one or more complete openings or braces and products obtained hence}

Electronic circular knitting machines of different diameters have recently attracted interest in the field because of their versatility, which can produce a wide range of semi-finished tubular garments such as bras, panties, dresses, pants, skirts, teddys, swimwear and functional clothing. Is dragging.

However, these knitting machines have their own technical limitations, such as shoulder straps, loops, and the lack of openings for inserting legs or arms, so that the aforementioned knitwear requires a hard and laborious finish such as cutting or sewing systemically. Do. In fact, to obtain loops, shoulder straps, and various openings, significant fabric is wasted and continues to adversely affect production costs.

The present invention relates to a method and apparatus for automatically producing tubular knitwear with one or more complete openings or straps, and to products produced with these methods and apparatus.

In view of this problem, the present invention provides a shoulder strap, which can at least partially reduce or eliminate the above mentioned technical / structural limitations, thereby eliminating fabric waste and achieving the original economic, technical, aesthetic and commercial purpose. It is intended to automatically produce knitwear with laces, miscellaneous miscellaneous openings. Accordingly, it is a primary object of the present invention to provide a method and apparatus for producing tubular knitwear having a three-dimensional or shape effect, while being made with continuous movement of the needle cylinder while providing a perfect shoulder strap or loop.

Another object of the present invention is to provide a method and apparatus for producing tubular knitwear with a perfect shoulder strap, strap or loop without at least cutting or sewing.

It is yet another object of the present invention to provide a method and apparatus for producing bras, panties, undergarments, skirts, trousers, and other functional garments without the occurrence of fabric sacking. It is another object of the present invention to provide a method and apparatus for producing tubular knitwear with simple or double edged or multiply straps or openings, made with the aid of a dial and using suitably selected needles or sinkers. have.

Finally, another object is to provide a method and apparatus for producing tubular garments of three-dimensional fabric produced by dividing the needle into several groups, alternately stopping some groups and operating the remaining needles.

The above objects are a method for the automatic production of tubular knitwear in a knitting machine with at least one needle bed as defined in the claims: producing a tubular knitted fabric of a first length having a cylindrical shape and ending with a final stitch course. ; Producing a tubular knitted fabric of a second length having at least one side open by excluding a predetermined number of needles of the needle bed in a knit forming process for a predetermined time; And automatically resuming the predetermined number of needles in the process of forming the knit to produce a tubular knitted fabric of a third length starting with the first stitch course.

Preferably, the predetermined number of needles excluded from the knit forming process completely releases the knitwear during the second length of knitted fabric production.

In addition, the needles excluded from the knit forming process are adjacent to each other during the second length knitted fabric production process.

Other objects are apparent from the description, the examples, the accompanying drawings and the claims.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

These results are easily achieved according to the exemplary and non-limiting purposes of the present invention, most of which relate primarily to circular knitting machines, in which the needle bed or cylinder rotates with respect to the stationary cam or vice versa. One or more thread feeders are provided in the feeder, electronically selectable to control the elements involved in the formation of stitching according to the work cycle or jacquard pattern, pneumatic or mechanical devices for withdrawing knitted fabrics and A dial with a selected needle or hook is provided.

Recently, many circular garments are assembled and completed by labor-intensive cutting and delicate and expensive sewing along certain lines. For example, in Figs. 1 and 2, the knitwear 1 having the double edge 2 is cut along the break line to form the rear portion P and the front portion A, and then the edge corresponding to the edge ( S) Sew. This work basically involves a significant amount of over 20% of the initial fabric volume, depending on size and model, which has a significant impact on the final price of the product. The present invention relates to needles or jacks that are directly or indirectly involved in fabric production by means of work cycles or jacquard designs, i.e., by means of everyday graphic states or control or memory devices, or by means suitable for any purpose, such as electromechanical, magnetic or optical devices. Implemented by setting or programming information related to elements such as jack).

According to the invention, the tube of FIG. 3 starts working from the double edge 2a with the aid of a hook of a dial (not shown).

After some coarse, corresponding to the symmetric lines 5, 5a, a complete release of the loop occurs by a part of the needle, depending on the work cycle or jacquard.

4 is an enlarged view of a portion 6 of FIG. 3. Once the manufacture of the double edge 2a is completed, a knitted fabric 30, such as a typical simple jersey adjacent to the symmetric lines 5, 5a described above, is drawn into the tuck stitches and welts shown in Figs. 12-15. It is characterized by knitting and deformed to the jersey 7 by appropriate selection of the unraveling type "non run" knitting needles to those skilled in the art.

To prevent the jersey 7 from loosening, use a few more coarse heat bonds that are capable of melting at a predetermined control temperature during final fixation just before releasing the loop along the line of symmetry 5a. Automatic release of loops or stitching with needles along the lines of symmetry (5, 5a) results in simple edges (8, 9) having the property of twisting themselves in steady state.

These aesthetic and functional products are suitable for knitwear aimed at young or practical consumers. Conversely, for customers with high demands, the aforementioned edges 8 and 9 are provided in a number of ways with elasticity, which is characteristic of the double edge 2a, in which the general hook of the dial selected for this purpose, or the needle portion of the cylinder, For example in FIG. 8 the even needle AP may be made using an odd needle AD which continues knitting while biting each last loop.

Therefore, the inner frill (Bi) of Figure 8 is generated, it is possible to three-dimensional knitting that can be adjusted widely in size and height. Finally, the double edge can be obtained using special knitting sinkers that can be ordered and loosened while holding the initial knitting strings.

It should be appreciated that the term "waste", which is a term known to those skilled in the art, can be located both inside and outside with respect to the knit tube. The release of knitting by the needle can be obtained in a number of ways, which can vary as needed or depending on skill or organizational elements. In a preferred embodiment, when the knitting machine or work cycle is set to the zero position, all feeds are canceled and the thread feeder is excluded and all needles in the non-operating position are stuck in the last loop. Thus, only the programmed needle rises completely in one feed to release the associated loop or stitch.

In this case, the knit tube is bitten by only some of the needles, and the forming process is started after the intervention of the mechanical or pneumatic movable element, which starts with a simple edge or a double edge, or, depending on the article, acts as a slit opener. According to the present invention, after the stitch forming process by the needle of a part of the cylinder for a given knitting area is completely interrupted by the program, the stitch forming process of the knitting area by the same needle is restarted by the program and theoretically continued. The traditional knitting lines can be produced by separating them completely, the former means the last knitting line, and the latter means the first knitting line produced after the interruption.

The undershirt-bra or simple bra, tubular knitwear 1 of FIG. 5, is provided with an edge 2a, which is detachably engaged with the central portion y, folded up in the direction of arrows F1, F2. Two open loops are formed to form the shoulder straps 20 and 21. Knitting regions 11, 13, 14 may have other knit structures as desired. In particular, the central portion 12 is structurally and functionally connected to the central portion y of the shoulder straps 20 and 21 or to adjacent portions, to support the breast in various ways. DB is a double edge that occurs after forming the shoulder strap (20). In another preferred embodiment of FIG. 6, the knitwear tube 1 is provided with a double edge 2a, an edge DB and an adjoining portion 2b. Longer than the lines in Figs. 3-5, between them, knitting dividers 5, 5a are formed in accordance with a new work cycle or jacquard design.

By separating the program along the dividing line 5, 5a, two loops 22, 23 that can be folded down are formed so that they can be placed side by side or overlap with each other. The central knitting area Z is controlled to select the needle appropriately so that less knitting is done compared to the periphery. 18 shows a bra and panties made in accordance with the present invention. The central part of the knitwear described above is a vertical area characterized by a knitting area (MO) similar to the interlacing of Table 2, such as the turk knitting of FIGS. 10-13 or the welts of FIGS. 14, 15 and one or more internal stitching frills of FIG. Bi).

The vertical knitting area MO has an aesthetic and functional purpose, with the center points indicated by arrows F positioned corresponding to the front elastic edges 2 breaking line horizontal lines indicating the respective rear edges 2b. It is sufficiently displaced compared to. This displacement is due to the presence of two factors in the final product, one because there are fewer knit strings with little elasticity compared to the periphery, and the other is shoulder straps 20, 21 which tend to rise or fall. Or loops 22 and 23 exist. In particular, the jersey fabric is aesthetically beautiful considering that it is originally structurally elastic. This knitwear features lower loops 22, 23 and upper shoulder straps 20, 21 that are joined or overlapped to function as seats. In addition, as known to the person skilled in the art, the so-called "mouth tooth" (G) may be automatically selected by the needle and appropriately added to the knitwear 1, or as shown in FIG. Sleeves M1 and M2 may be padded along (S, S1). The tubular knitwear 1 of FIG. 19 is in the form of a bathing suit with two shoulder straps 20 and 21, and these shoulder straps are formed so that the upper edge is separated along the lines 5 and 5A.

The two lower loops 22, 23 are also manufactured such that the lower edge is partially separated along the lines 5B, 5C.

Thus, the upper and lower ends of the tubular knitwear 1 are provided with shoulder straps and loops that match each part of the body. In particular, the lower central portion K having a sheet function is formed of loops 22 and 23 that overlap and fold downward. The invention also features a knitwear 1 shown in FIG. 22, which first forms the outer part A and the inner part B, both of which have a string 20-23 and a center. The double edge 2 is provided. Thus, in this case, one part is overlapped with the other to complete the knitwear consisting of two body fabrics, but the number of shoulder straps can be adjusted to four.

According to FIG. 23, the knit forming process is interrupted and resumed along line 5 to automatically form one wide string 20a improved with double welts. By repeatedly interrupting and resuming the knit forming process in the knitwear operation, it is possible to form holes 01 and 02 with a simple edge BS or holes 03 and 04 with a double edge DB. According to the knitwear 1 shown in Figs. 24-28, the present invention can be realized according to the method schematically shown in Figs. Unlike in steady state, no instruction or impact related to the needle is sent to the part of the needle according to a defined program that matches the original design. For this reason, in the process of forming a knit by the needle, a forbidden region lacking an input or an instruction is generated, and an adverb (FF, floating threads) is generated in whole or in part of the forbidden region instead of knitting (M) of FIG. Therefore, the size of the nose varies throughout the fabric or knitwear, resulting in structural deformation, which is suitable for making three-dimensional fabric shapes that can match different parts of the body.

The adverbs FF of FIG. 7 may be fabricated using several needles A properly spaced in the entire forbidden area, and the dual purpose of reducing the adverb length is to satisfy the knit interlace. Thus, the present invention can be implemented by forming the knit fabric produced by only a part of the needles provided in the relevant areas with the adverbs. For example, only the even needles or the pair of needles may be worked alternately, by dividing the needle into three groups and limiting one or more needles. As shown in Fig. 8, as long as the working needles for a given area are alternately present simultaneously for a relatively long time, it is sufficient to produce the original stitched fabric, which is limited by the formation of the working needle and the associated loop AD. Interrupted and interlaced with the needle and loop AP, it is possible to form closed nitrile with the two-layer prill Bi of FIG. 8 inside a typical stitch tube. This frill (Bi) is inoperable and features a full-stitch stitch front by loops of the needle (AP) or the elongation of the stitches, which are excluded from the manufacture of the frill, which can be variable or repeatable in height or width. . These frills (Bi) are particularly arranged in a zigzag form, which is advantageous for supporting the body in three dimensions and exerting a padding effect (see FIGS. 31 and 32). The method described above is shown in FIGS. 24 and 25, which show another embodiment of the invention in which the knitwear 1 is fitted to the body. In particular, FIG. 24 is a side view of a knitwear 1 having a daily elastic edge 2. In this embodiment, the two-ply formed frills Bi are formed only on the inner lower part of the knitwear 1. With the aid of the computer controlled stitch forming process, the density of the stitchings 13 can be widened only in the designated areas 11 to improve the body matching effect. In the lower part of the knitwear, in any case, the density of stitching 12 or stitching MO is reduced and there are knit frills Bi produced by the technique shown in FIGS. 25 shows the final result, that is, the knitwear 1 is formed in the direction of the arrow F, and the inner knit frill Bi is formed to match the neck. The knitwear 1 may simply be manufactured as an initial or final part of a functional garment, such as a hat or warm clothing or a dress. 26, 27 differ from the above-described embodiment in that there is a simple edge 32, a wound outer waist 31, or a simple winding edge 33,34. The knitwear 1 of FIG. 28 is characterized in that a predetermined number of needles appropriately arranged and spaced at the start of manufacture of the knit tube 35 are grouped and excluded from the production process for a predetermined time.

In this setup, more transparent stitching is generally produced in terms of columns or ribs that are systematically represented by dark horizontal lines.

At the beginning of work with the needle, holes 36 in FIG. 29 are created, which can be properly positioned to provide an aesthetic.
