Method of making tights and goal direction to carry out the procedure

The invention relates to a method for producing tights and to a device for Execution of the process on an LL small circular forming machine, which is equipped with at least two knitting systems.

Tights are "so far on the LL-] H. single-round stripe machine manufactured in such a way that two length parts are knitted, which are then cut open in the trouser part and sewn together with an additionally knitted insert piece for the required elasticity. The pantyhose produced in this way, which are intended in particular for children, have a good shape of the pant part on, but their production is very time-consuming and material-intensive, since an insert is also knitted must be and when sewing together another seam is required.

EPO COPY §

Besides the economic disadvantages, wearing the \

Tights the seams visible, the aesthetically disturbing j

work and the presentation goods of the I Reduce tights. "

To eliminate these disadvantages, a weitere.s process for the preparation of children tights on LL-circular knitting machine has been developed, the time and material _(overflow wall in such a manner reduces that no insert is inserted into the trouser portion and is thereby also saved otherwise necessary seam.

The essence of this process is that in the trousers part in a knitting system a row of stitches, consisting of one Combination of left stitches, right stitches and catch stitches, is formed, with these stitches in a next knitting system knitted with a row of stitches, the purl and knit stitches formed from a separate thread contains. This method of making tights on LL small circular knitting machines is particularly useful for suitable for the case in which the knitted fabric is formed with a continuous pattern and the pattern device is during of the entire knitting process is in action. The disadvantage of this method of making tights consists in the fact that an improved stretchability is achieved in the trouser part, but the required stretchability not yet fully corresponds. In addition, this existing elasticity is proportional in the entire area of the trouser part distributed, which does not guarantee the optimal shape of the panty part of the tights.

In particular, this disadvantage is noticeable in the seating area of the trousers part, of even greater demands on the _t stretchability of the knitted fabric is than the opposite front area of the trousers part of the case.

For the production of these tights an IiL small circular knitting machine with known and not shown needle cylinders and with two knitting systems I, II (Fig. 5) is equipped. In the first knitting system I, the thread Pj (FIG. 5) | and in the second knitting system II the thread Pj _{1 is} fed. The knitting needles (not shown) are actuated in the lower needle cylinder by lower needle slides 7 (FIG. 6) which are provided with working feet 8 and pattern feet 9. J

Below this mentioned needle slide 7 are further working \ tätigungsmittel, including intermediate slide lo arranged, which are provided in the upper part with guide feet 11, and below these disposed work feet 12th Furthermore, further pattern slides, not shown, can be arranged below the intermediate slide Io (depending on the type of LI small circular knitting machine used), for example for the purpose of patterning. In the upper needle cylinder, the knitting needles are operated by upper needle slides 13, which are also provided with working feet 14 and sample feet 15.

During the rotary movement of the needle cylinders in direction S, the intermediate slides Io are also moved by means of guide feet 11 guided by a lock ring 16. In the area of the first knitting system I is in a known manner by means of a lock part 17 the needle selection for 1: 1 distribution was carried out. A further guide ring 18 is arranged above the lock ring 16. Between the lock ring 16 and a guide ring 18 a radial lock part 19 is arranged, which actuates the sample feet 9 of the lower needle slide 7. Above the mentioned radial lock part 19 is a lifting part 2o attached

arranges that the working feet 8 of the lower needle slide 7 actuated, the so through the web A until it comes into contact with the central trigger part 21 and with the cam lock part 22 run, which are also arranged above the guide ring 18. In the second knitting system II is between the SchloßriBg 16 and the guide ring 18 a radial lock part 23 is arranged, which has a recess for the catching position in the buoyancy part owns. The aforementioned radial lock part 23 works with a buoyancy part 25 which has a recess for the catching position possesses, together, which in the direction of rotation S of the needle cylinder has a central cam part 26 and a ball cam part 27 to operate the working feet 8 of the lower needle slide 7 follow.

In the first knitting system I, a radial arrangement arranged in the lock ring 28 is used to actuate the upper needle slide 13 Lock part 29, which the working feet 14 of the upper needle slide 13 through the path B to the first fixed buoyancy part 3o leads. Furthermore, a guide part 31 follows for the Ha- * delübergabe, which is provided with a horizontal recess 32, which enables the achievement of a catch position B in the Lane B allows. A radial counter-lock part 33 is arranged vertically to the lock part 17 via your lock ring 28. There is also above the aforementioned lock ring 28 a radial lock part 34, which the sample feet 15 of the upper Needle slide 13 actuated.

The knitting needles forming the front area 5 of the trouser part 3 are assigned upper needle slides 13, which are long Have sample feet 15 and the knitting needles forming the seat area 6 of the trouser part 3 become upper needle slides assigned, which have short sample feet 15.

The selection of the needle slide 13 is then arranged in the first knitting system I by one in the area of the lock ring 28 radial lifting part 41 carried out.

The pant part 3 of the pantyhose is according to the invention on a LL small circular knitting machine equipped with two knitting systems formed as follows:

The needle cylinders rotate in the direction of arrow S, and the feet of the upper and lower needle slide 7, 13 or the intermediate slide Io are guided by a fixed lock system. The lower needle slide 7 move through the knitting systems I, II in the path A. The upper needle slide 13 move when passing through the knitting systems I, II in track B. The individual lower and upper needle slides 7, 13 associated knitting needles are distributed 1: 1 in this case. This knitting needle distribution is by means of a Lock part 17 carried out, which acts on the working feet 12 of the intermediate slide Io. The intermediate slider Io point short and long working feet 12 on. The intermediate slide Io, which is provided with long working feet 12, lift by means of

NadelSlider 7 pushes the knitting needles into the upper needle cylinder at. The short working feet 12 of the intermediate slider Io become not detected by the lock part 17 and therefore run past this. The assigned knitting needles remain in the lower needle cylinder and are operated by the lower needle slide 7.

In the first knitting system I the thread Pj

fed. In the second knitting system II, another thread P _{11 is} fed to the same needle heads. As a result, two rows of stitches in the front area and one row of stitches in the seat area are created from these fed-in threads Pj, Pj j during each revolution of the needle cylinder. The knitting needles that are in operation in the lower needle cylinder form the right-hand stitches and the knitting needles that are in operation in the upper needle cylinder form the left-hand stitches Z. During the knitting of the seat area β of the trouser part, the needle distribution in the lower and upper needle cylinder remains unchanged and therefore, a knitted fabric consisting of alternating left wales L and right wales R is formed.

The front area 5 of the trouser part 3 can essentially be formed in two binding variants. The easiest "Variant is that the knitting needles of this needle cylinder half in the first knitting system I and in the second knitting system II do not form any tuck loops. This creates a knitted fabric, in which, for example, a 1: 1 distribution consists of right stitches R and left stitches Alternate the existing left wales L.

An even greater extensibility is achieved in the torso area 5 of the trouser part 3 by means of a binding shown in FIG. Stitches are formed in one of the two knitting systems I, II. In the exemplary embodiment, in the second knitting system II, the thread Pj _{1 is formed} into left stitches Z and right stitches X, each with a tuck loop, because the knitting needles pass through the second knitting system II as a result of the attachment of the radial cam part 23 in the tuck position A _Y be raised.

Λ.

In the first knitting system I, the thread Pj becomes a left stitch Z and right stitches formed because the radial buoyancy part

" ^l0 EPO COPY

41 raises the knitting needles by means of the upper long working feet 15 of the needle slide 13 into the containment position.

In an exemplary embodiment not shown, the front region 5 of the trouser part 3 can have a different mesh combination contain those from purl stitches Y each with a 'tang handle and consists of knitted stitches. Such a front area 5 of the trouser part 3 has one of the areas shown in FIG .Binding appropriate stretchability, but are different for the formation of the mentioned mesh combination Settings of the radial lock parts 23, 41 or different lengths of the working feet 8, 14 of the needle slide 7, 13 required.

This sequence of revolutions 0 .., Op, 0, ... of the needle cylinder repeats itself until the plane indicated by the dividing line k is reached.

In order to achieve the required stretchability of the pantyhose described, it is necessary, for example, in one 1: 1 needle distribution, such a lock arrangement too use that during the knitting of the length parts 1, 2 and the front area 5 of the pants part 3 in one of the Knitting systems I, II enable the formation of the catch stitches.

For known body-related reasons, a great elasticity is required in the seat area 6 of the trousers part 3, which what is achieved thereby is that right wales R and left wales during knitting of this seat area Alternate L. These wales forming stitches are knitted stitches X each with a tuck loop (Fig. 4).

This combination of meshes with tuck loops is achieved

by the short sample feet 15 of the upper needle slide 13 to form the seat area 6 in the specific area of the needle cylinder pass the radial lifting part 41 and the short working feet 14 of the upper needle slide 13 through the "recess 32 of the guide part 31 for the needle transfer into the catch position By. That means, that in the first knitting system I the thread P ^ is formed into knitted stitches with the upper knitting needles.

The pad "Bjj" supplied to the next knitting system II is formed into left stitches with the upper knitting needles and tuck loops with the lower knitting needles because the knitting needles working in the lower needle cylinder move in path A, with the result of the deepening of the buoyancy part 25 and the setting of the radial lock part 23, the knitting needles mentioned in the second knitting system II pass through the lift position Ax for catch.

the upper portion has the length-parts a stretchable knitted fabric bond have, by knitting a smooth upper part of _t, for example, right-left, or right-right-bond with Pangbindung ir | a wale can be achieved on all the needles in the lower or in the upper needle cylinder.

When using this process, there is a small circular knitting machine no way to knit this stretchy bond in combination with patterning because that is arranged The buoyancy part alternatively the needles either in the enclosed position and by exchanging this buoyancy part brings in pan division or a vertical arrangement of the ' Buoyancy parts that cause pang and loop formation.

An apply all necessary cam parts for knitting a stretchable bonding in combination with screening for the previous LL small circular knitting machines loading \ rides great difficulties due to the non-existing installation space.
To solve the problem, it was proposed to use two length

parts with a continuous pattern with a so-called To assemble insert piece.

The insert required for this must also be knitted and cut as an individual part.

When assembling an additional seam is required, due to the seams in the crotch area, the elasticity is increased in the upper leg and thus also the fit in this area is limited.

Another process for the production of children's tights on LL small circular knitting machines was also developed, reduces the time and material expenditure in such a way that no insert is inserted into the trouser part and thereby a seam is also saved.

To achieve the required fit, a row of stitches consisting of Left-right and tuck stitches formed, whereby these stitches are knitted with a row of stitches in the other knitting system that only contains left and right stitches.

In this way, an improved stretchability is achieved in the trouser part, but the same as the required stretchability does not correspond. In addition, the elasticity achieved in this way is proportionally distributed over the entire area of the trousers part, which does not guarantee the optimal shape of the panty part of the tights.

e) The invention can be used on LL small circular knitting machines for production Circular knitted goods with high elongation requirements, especially for tights without insert or other Outerwear can be applied.

f) The above confirms those that have already been carried out in-house tests and the wearing tests of the tights.
