Abstract

To form the pantyhose product two knit hoses are formed on both needle contours nesting and connected along a longitudinally aligned connection zone - along the center line of a longitudinal separation step is made. To ensure the excellent quality of this connection zone, the yarn is entangled by a part of the needles of a font selected at regular intervals and by some needles of the opposite font, whereby the selected needles are not expelled and do not pick up any yarn, while the corresponding needles are opposite Fontur knit the yarn with the stitch of the knitting tube formed by the needles of the first Fontur and so form Verbindungsbruecken, the needle selection is made so that those selected and not expelled needles in the next course receive and entangle yarn.

A process for the continuous production of a tights product on knitting machines having two needle shapes and knitting machine for carrying out the method

Field of application of the invention

The invention relates to a process for the continuous production of a panty hose product on knitting machines with z-shaped contours and at least two feedings, one per contour, in which stitches are knitted on both needle needles; ine be formed erlisgend in and and the two "Gestrickschläüche are connected along a longitudinally oriented Verbindungsζone that eist a length ¹ ^ ₃ which corresponds substantially to the length of the body portion of the pantyhose, and is taken along the center line of a longitudinal 2rennschnitt · so "like e'-ine'3trickiu £ 3 <5hine ^{; i;} for the office management of the procedure,

Characteristic of the known technical solutions

Known processes for the production of panty hose products

are particularly suitable for Doppelzylinderruiidstrick-

machines or circular knitting machines with a cylinder and a dial «,

Such methods are based on the formation of two nested knit hoses on two circular "hawk shapes". In these methods, the leg-related part is obtained from separate tube-like hoses.

In the portion corresponding to the panty portion, the tubes are connected along at least one longitudinal web and separated along a line lying longitudinally therebetween.

The inner tube is then withdrawn and sent so that an open, symmetrical tights product is obtained.

In a known method, the panty portion is made under continuous movement of the two cylinders. This is done by forming the clew-shaped parts connected along a longitudinal zone, with needles of both contours being actuated to: with one or more saddle feeds. create a mesh structure with continuous right and left stitches «

The method further provides for the execution of a longitudinal "running" Irennungsschnittes (s * IT 9522 A / 80 and * SP 81 830 142 6).

This method ensures zviar a high output speed} but the demands of consumers. a high strength and durability of the panty only partially fulfilled. In particular, the appearance of the panty section can not satisfy, this is due to the fact that the zone connecting the two knit hoses on at least one side of a mesh-free route

According to a further feature of the invention, the selection made in a course of stitches is made after formation of at least one row of normal stitches. same meshes repeated,

However, it is also possible that the selection of stitches made in one course is repeated by at least one wale in the next course,

In a further embodiment of the inventive concept, the same Uadelausvvahl after interposition of at least one row of stitches on a- SOntur for the zone which connects the two knit hoses, repeated *

It is also conceivable that not only the position but also the number of needles selected on a contour changes at regular mesh intervals,

FIGS. 1 to 3 show preferred embodiments of the method according to the invention,

The zone 52 connecting the knitted fabrics 57A and 573 is in this. 2all carried out within a sector ₃ the approximately 32 positions of the needles 54; 154, wherein a longitudinally extending cut is made to coincide with the. Position 16 matches *

Positions like 10; 16 and 22 must be separated from each other by a certain number of needles depending therefrom, such as the distance between the burs of stitching by the upper cylinder plates and. the plane '' - '' of the stitching :, the lower: cylinder-is-selected-is-to-table, shows-siohj -that positions,; such as 10... \ 6, or 22- at least one distance from have to have three tribes from each other «

Without departing from the bottom of the present invention, however, it is also possible to change the number and position of the needles 5 ² H 154 in the sense of the inventive merchandise selected for the formation of the connection zone 52: see below

Figs. 4 through 10 show the connections made between the two knit tubes 57A and 57B after actuation of the I ¹ delays corresponding to positions 1 to 32; 154 according to the in the.5 ¹ Ig. 1 to 3 presented selection »

The operation of the! Blames 5 ^; 15 ² ^ i- & the connection zone 52 of the two knit tubes 57A; 57B, each of which has been produced with a supply 56 for the yarn 33 , leads to the formation of two goods with smooth meshes _t, which are pike-links and left-noses.

These goods include bridging bridges , each of which, depending on the place where it was formed, has been given a specific reference numeral in the figures of the drawing, namely 110 ^ 116; 122; 102; 108-; 114; 118; 112; 120; 126 and 132.

In contrast, Fig. 7 shows the S ¹ all reverse bridges, which now go from the knit tube 57-ä- and knitted in the knit tube 573 and then go out of the knit tube 57B and are incorporated into the knit tube 57A * These obviously eingeschränlrten examples clarify the precise , large "variability of the possible solutions as well as the resulting, aesthetically pleasing;
