DE2548208C3 - Method for making a one-piece pantyhose - Google Patents

Description

The invention relates to a method for producing one-piece tights as described in the preamble of the claim specified genus.

Such a method is the subject of the earlier application according to DE-AS 25 37 117, which is not to has resulted in a patent. This method works with a system. To just in Every fourth, eighth, etc. row of stitches can be reduced or widened with this method between with each reduction or expansion step two or more times.

From DE-PS 8 18 542 a method for producing pantyhose is known in which first a trouser leg is knitted round and then swung and at the same time reduced. Then it will be while maintaining the working area, continued to oscillate until a section of constant angular circumference the has reached the desired length. Then it is extended analogously to the previous reduction and finally so second pant leg knitted in a round shape. This creates a piece of goods that has two over a gusset and over the adjoining, diminished or widened areas connected legs and one along the side the edges have open trousers part which is closed at the top along a folding bend. After blasting off of this piece of goods from the machine, the edges must be closed by a linking machine. Finally, the product must be cut and hemmed along the bow.

It is also known to manufacture pantyhose in such a way that a pair of long woman's stockings can be worn Their tops are cut open and sewn together to form a trouser part with an additional gusset will. Such tights have the advantage that they can be made to fit and at the entrance with a comfortable, elastic reinforcement edge knitted on the machine can be provided. But they require a separate downstream knitting process Cutting and sewing process.

On the other hand, it is also known to have tights in the form of a single tube on a circular knitting machine to manufacture, this tube has the shape of a banana in this way tights can be produced economically, but they are not sufficiently elastic in the hip area and are flexible enough too short according to the required size, so that they are uncomfortable to wear. It is also true that an elastic edge can also be worked on the manhole during the manufacturing process can. Due to the single-surface working method, this curls inwards when worn, see above that the wearer has a bulky and incisive rubber cord on the body after a very short time

The object of the invention is to create a method of the type explained above, with which a One-piece tights in a particularly economical way with sufficient elasticity in the height direction Connection of the two halves of the trousers can be made.

According to the invention, this object is achieved by the characterizing features of claim 1.

The multi-system work enables economical production. Since only at is reduced by a system, the height of the is still sufficient and comfortable to wear Partly achievable. The staggered pendulum of the systems results in a pyramidal design of the Connection between the pant halves, which in the longitudinal direction of the connection has good elasticity owns

In the drawing, a one-piece pantyhose manufactured according to the method is shown schematically.

These one-piece pantyhose consist of a first panty leg A, a first panty part half B, a first double rim half Q, a second double rim half F, a second panty half G and a second panty leg H.

The trousers are made in one piece on a circular knitting machine as one-piece tights. After the first leg A has been completed using the usual circular knitting process, the machine is switched to pendulum gear. After about 50 needles (out of a total of 400 needles), which form the gusset area Z, have been switched off from the knitting process, the first half of the trousers part B is manufactured with a contact width of about 350 needles. With a medium pantyhose size, approx. 100 needles are removed from the knitting area by continuous reduction. Then the first double edge half C is made from elastomer yarns on the remaining approx. 250 needles, with simultaneous reduction. After reassigning and completing the first double edge half C , it is blasted off. In the two reduced zones D and E , however, the stitches remain on the needles. On the detached needles, but two more needles on both sides in order to maintain the connection to the detached double edge half C , the second double edge half F is started. With the needles simultaneously widening in zones D and E , the second double edge half Fin is manufactured in the aforementioned manner. After the transfer, the second trouser part half G can be produced. Here, too, the needles of zones D and E have to go back into the knitting area in the appropriate order

be brought, with the connection to the first pant half B is made at the same time. Upon reaching the 350 needles Width of the needles 50 of the crotch region .Z be brought back into the knitting position and the machine of the reciprocating motion in the idle position = · switched Then, the stocking leg Hin known manner is manufactured

In the production of the first trouser half B, only system I reduces, which results in the reduced traces D and £ . The intermediate system II commutes m from the line Di to El. The intermediate system III commutes (staggered) from D 2 to EZ

It is declared that no protection will be invoked for a method for producing a one-piece pantyhose, in which the pant part after completion of the first stocking leg to achieve horizontally running rows of stitches also in the corresponding Pendulum gear is created, but only in one system.

Claims (1)

Claim: A method for producing one-piece tights on a circular knitting machine, in which the first trouser leg is knitted in a circle, then a needle sector with attached stitches is switched off, then a trapezoidal piece of the first half of the trousers is knitted in a pendulum gait while continuously decreasing after several rows of stitches, then onwards a first part of a double edge is knitted in the pendulum motion under reduction, then this first double edge half is blasted off, a second part of a double ^{edge is knitted in the pendulum motion in the pendulum motion under the ι r} , previous reduction, then a trapezoidal piece of the second The trouser part half is knitted in a pendulum gait under the previous reduction, the double edge and the trouser part halves are connected to one another, and finally the second trouser leg is knitted round wi, using all the needles rd, characterized in that it is knitted in three or more systems and is reduced or expanded in the pendulum gear only on one of the systems, while the other systems knit staggered without reduction or expansion.
