Description

Description of the invention

A first object of the invention is a method for producing a product in the form of a pantyhose on knitting machines with two needle bars, in which the courses are formed alternately and successively by two opposing needle areas of the two needle bars using one or two yarn guides. By means of this method, the production of a nearly complete and error-free product can be achieved. The two ingots are formed in a circular knitting machine, as disclosed in another, simultaneously to the same Applicant's application (IT Application No. 9357 A / 89), advantageously by a cylinder and by a board or disc

 The method under discussion essentially comprises the following stages, which are combined with one another:

the initial formation, with crossed needles of two first, spaced-apart needle areas, of at least one row of connecting stitches for closing the tips:

the formation of the tubular leg parts by means of conical rows:

the formation of at least one locking row in the said region of the step at the end of the tubular leg parts, the needles being crossed in the region of the step located between the said first two spaced-apart needle regions;

and the subsequent formation of continuous conical rows for the tubular fabric of the trouser portion with all the needles of said first two regions and the crotch region.

With the help of the central and gradually increasing parts of said first two needle areas, leading to the formation of the legs

are provided, it is possible at the beginning to produce conical loops of gradually increasing dimensions, so as to form the tips of the closing rows.

According to an advantageous embodiment of the method at least two are during the closing of the step

adjacent needles, which were previously effective in forming the tubular leg parts, also crossed at each end of the crotch area. This reduces and even eliminates the formation of eyelets at the ends of the closing area dos

Step, which increases the quality of the product. In addition, after the partial formation of the tubular leg parts, an increasing number of needles may be in each

the first needle portions are used, from the end that the other end of said first

Needle areas is closest. As a result, the size of the cross section of said tubular parts can be progressive

increase.

Another object of the invention is also a garment in the form of a pantyhose as defined in the Claims and explanations in the text. The invention should be better understood by the following description and the accompanying drawing, which is a practical, but not

limiting embodiment of the invention will be better illustrated. The drawing represents the following.

As shown on the attached. Drawing designates the line ABCD the end profile of each tip ends of the product in the form of a pantyhose. It can be seen in particular from FIG. 2 that at the beginning of the formation of each of the two tubular regions which make up the leg parts and designated T in FIG. 1, at least one row of connecting stitches is formed, simultaneously activating the two needle bars, with which the tubular product is processed at the stage of the individual tubular areas T of the leg parts. The formation of this course of stitches or these few rows of connecting stitches is done by macerating the activated needles, for example alternately on each bar or in such a way that they do not obstruct the needles of the other bar. The position of the needles is clearly shown in Figure 6, denote in the 10 and 11, the two bars of the needles 13 and 15, wherein the two bars can also be designed as a round bar. Especially in circular knitting machines, one of the ingots, for example the Barre 11, is a cylindrical and the other 11 is a disc-shaped bar. When the needles 15 are activated to grip the thread, they are raised to the 15A position and then lowered to form the stitch. The needles 13 of the bar 10 are pushed outwardly to the position 13 A to grasp the thread, and then retract to form the mesh inward. If the needles on both ingots have to be activated, this activation will be done only partially, for example with a 1: 1 selection, and in such a way that the needles of one barre will be the same as the other barre at the intersection, which will be in accordance with the Representation in Figure 6, not hinder.

In the arrangement of crossed needles known per se, at least one row of connecting stitches along the needle front is produced to form the individual tubular portions of the leg portions, ie along the line ABCD shown in FIG. 2 , which designates the closing line of the point.

Immediately thereafter, the formation of the tubular product T begins with conical rows, which are alternately worked on the two ingots. Thereafter, a beginning along a short intermediate piece of the line ABCD, for example, along the part CD to - with dan needles of both ingots - alternately and consecutively conical rows Po form, which begin with the dimensions of the front CD and then with alternating use The needles at both ends of the active needle area of both ingots along the arcs gradually increase from C to A and from D to B, in such a way that the dimensions of the conical rows Po increase progressively to the maximum between the ends A and B of the increase the activated needle area, ie to the extent P of the needle front, which is intended for the formation of the leg part T. Thereby, in the formation of the tubular leg part T, for each of the tips of the tubular leg parts T, a shaping of said tips is achieved by increasing the use of needles of the initial region CD to the end region AB.

Thereafter, the formation of the two tubular parts T over the entire length of the legs is started or, after a certain part of the tubular product has been knitted, an increase in the cross section of the individual leg parts is obtained (in addition to the conventional, gradual increase in the length of the courses), wherein an increasing number of needles are inserted at the inner end of the individual needle work passages and are started, for example, at the points E and G shown in FIG. This leads according to the thigh in the worn product to a progressive increase in the dimensions. Thus, a working front is created along the line KFHL. The area FH represents the so-called crotch area, which must be closed before proceeding to the formation of a single trouser part area Co, the size of which corresponds to the entire working front KFHL.

To close the lying between the two points F and H part Z, d. H. for closing the step, the needles of the two ingots lying in line with this area FH are driven in accordance with the above description for the initial closing seam of the tips so that the needles intersect. In this way, a closing row of connecting stitches is formed in the area FH, which represents a closing seam Z. Thereafter, the entire needle front of the two opposing needle bars lying within the line KFHL is activated to form the trouser portion Co, which is subsequently closed along a covenant or seam designated MM and NN. This collar can be made in a conventional manner with a tubular double seam, d. H. a seam with a round cross section. The following procedure can be used for making the connecting stitch row along the break-in closing lines ABCD of the tips and along the line F, H or F1, H1 of the step with the crossed needles 13 and 15 of the two bars 10 and 11. With a 1: 1 selection, the needles 15 of the cylinder 11 are raised without feeding a thread. Thereafter, the needles 13, which are 1: 1 selected and shifted with respect to the still raised needles 15 A, progressively raised and lowered, while the yarn is fed and detected by the needles 13 A to 15 A on the web of the still raised needles to form the stitches. Subsequently, the stitching yarn is fed to the needles 15A, which are lowered. Then a further row is formed with the needles 13. This procedure can be repeated before starting the formation of the tubular fabric.

In the application of the previously described method-d. H. when using the needles of both ingots in the area FH of the step along the front Z, the needles are crossed, but this is limited to the area of the needles that lie between those needles with which the end part of the two tubes T made for the legs At the ends of the region Z, which is schematically illustrated in FIG. 7, irregularities may occur due to the formation of small open eyelets O at the ends of the region Z and thus in a line with the points F and H mentioned above , In order to prevent this disadvantageous formation of the eyelets O, according to a particularly valuable aspect of the invention for working with crossed needles, a needle front is activated which is slightly larger than the aforesaid front FH, such that the locking row passes along the crossed needles the designated in Figure 4 front F1-H1, which is slightly larger than the front FH is extended. This frontal increase can be limited to a pair of needles belonging to the two bars and placed on the outside of each of the two ends of the area FH, the pair of needles belonging to the needle front with which the corresponding tubular product T was made. In practice, the gauge of the tubular leg portion T does not change, however, the use of one or two pairs of needles on the outside of each end of one or two pairs of needles on the outside of each end of the area FH has the advantage of reducing or even eliminating the formation thereof shown in Figure 7 eyelets that can represent a disadvantage for the finished product. In this way, a closure shown in Figure 8 is obtained, which is an improvement over that illustrated in Figure 7.

The control of the needles to their intersection, which takes place - on each front - in alternation to avoid mutual disabilities, can be achieved with any type of selection modes known in knitting machines. The product obtained is particularly well processed, with almost no manual intervention outside the machine on the product must be made.

The product made in accordance with the invention has two tubular leg parts T consisting of conical machine rows Po and P (Figure 10) and rows R1 (Figure 9) extending longitudinally from the legs T into the panty part Co by continuously extending conical rows of stitches P1 (Figure 10) formed. The rows of stitches of the trouser portion are formed by the extensions of the courses R1 of the legs T and in the central area - both front and back through the rows of stitches R2 (Figure 9), which are at a closing row Z along the area FH., And up to the edge MM-NN extend. The so-called step is formed by a closing seam in the region Z along the line FH (or F 1 -H 1) between the two legs, wherein the closing seam in the region Z is produced by means of connecting stitches which are formed by crossing those needles of the two parallel bars. with which the courses R 2 of the tubular fabric of the trouser part Co are knitted. The trouser part has neither a longitudinal seam nor any seamed fabric inserts, such as the so-called gusset. The tips also have a locking row ABCD, which is produced by means of connecting stitches, which are formed by crossing the needles of those areas of the two bars, with which the tubular structures of the two legs T are knitted. Thus, no seam is present in the tips.

The portion between the points F and H in the area of the step may vary depending on the carrying requirements of the Garment and also of the manufacturing requirements have a different length. He extends into Transverse direction. Due to the use of needles at the inner ends of the working needle areas of the two billets during the formation of the Legs T, the tubular structure of the legs T additional stitches in the rows of the areas EF and GH (Figures 1 and

11) and thus additional longitudinal stitch rows R3 (Figure 11) beginning along the areas EF and GH. These

additional longitudinal rows R3 also extend over the trouser part to the edge MM-NN.
