(54) METHOD OF KNITTING TERMINAL COURSES OF AN ELASTIC WELT OF A SOCK ARTICLE (71) We ELITEX, Koncern Textilniho Strojirenstvi of Liberec, Czechoslovakia, a body corporate organised and existing under the laws of Czechoslovakia do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to a method of knitting terminal courses of an elastic welt of a sock article which is knitted in the direction from the toe portion to the welt thereof.

It is known that in knitting such articles with closed toe portions it is preferable to knit the article from the toe toward the welt thereof since with this method it is possible to obtain a high quality closure of the toe portion. However, upon completion of the knitwork in the welt thereof, there arises a problem of a run-resistant termination thereof if the welt has to have an aesthetic appearance and, at the same time, to be sufficiently secured against unravelling.

It is known that the problem is solved by a double welt formed on the termination of the knitwork. The termination is performed on the wrong side after the welt has been transferred. A disadvantage resides in an increased material consumption and further, the output of the machine is reduced in view of the time needed for knitting the double welt. Another disadvantage resides in that the welt comprises double the number of rubber thread courses and, therefore, the welt is too right.

There is a known method of knitting which partly solves the problem in that after completing the leg portion, the last course of stitches is transferred into a second knocking-over plane and a new starting-up course is formed on needles in the first knocking-over plane and after knitting the welt, the starting-up course is joined by a number of courses to the last course of the leg portion which is deposited in the second knocking-over plane. The drawback of the method resides in that the welt is turned with its wrong side onto the right side.

The object of the present invention is to remove the above mentioned drawbacks in a simple manner and in high quality.

According to the present invention there is provided a method of knitting terminal courses of an elastic welt of a sock article which is knitted in the direction from the toe portion to the welt thereof, wherein after knitting the last course of the welt structure, a number of tuck courses of rubber thread are knitted, whereafter the terminal courses are knitted in a structure which substantially restricts unravelling.

An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawing of terminal course of a welt.

A sock article is knitted on a three-feed sock knitting machine, starting from a closed toe portion, and continuing via instep, heel and ankle or leg portions, as far as an elastic welt. The elastic welt is knitted of bulky yarn P1 which is lapped into all needles in the first feed, a normal yarn P2 lapped into odd needles in tuck positions in the second feed and into even needles in their normal positions, whereafter, in the third feed, rubber thread P3 is lapped. This results in a highly elastic structure as shown in the drawing. In the next step the first and second feeds are put out of operation and knitting is carried out only in the third feed point wherein the rubber thread P3 is knitted-in by needles divided in 1:1 proportion with the operative or odd needles passing in their tuck positions.This goes on for a number of revolutions so that the tuck courses substantially form only one course A of rubber thread P3. In the exemplary embodiment the course A is formed on triply lapped rubber thread P3. As the next step, the second feed is put into operation, wherein yarns P2 and P2' are simultaneously lapped, the third feed being put out of operation and anti-ladder courses being formed in a known manner. Thus the yarns P2 and P2' are lapped, at first into odd needles in order to close the preceding tuck course A and dial sinkers are projected above the even needles and dial loops are formed of yarn P2 which is lapped by a higher positioned guide, the yarn P2' forming a float-plated pattern since the even needles are in their inoperanve positions.In the next revolution the needle distribution is changed so that yarns P2 and P2' are knitted-in by the even needles and the odd needles are in their inoperative positions, the dial sinkers being projected above them and dial loops are again formed of yarn P2, and yarn P2' is again floated. In the next step or in the next revolution all of the needles then rè-take the dial loops of yarn P2 and draw them through the double loops of yarns P2 and P2'. Thus the article is complete and cast off the needles.

The main advantage of the invention resides in that by laying a number of rubber thread courses just before forming the anti-ladder termination, one obtains a constriction of the welt edge to the desired diameter, further a reinforcement thereof, whereby the welt acquires a desired shape as well as quality.

WHAT WE CLAIM IS: 1. A method of knitting terminal courses of an elastic welt of a sock article which is knitted in the direction from the toe portion to the welt thereof, wherein after knitting the last course of the welt structure, a number of tuck courses of rubber thread are knitted, whereafter the terminal courses are knitted in a structure which substantially restricts unravelling.

2. A method of knitting as claimed in claim 1, wherein a number of rubber thread courses are knitted in 1:1 needle distribution, in tuck structure, whereafter the terminal courses are knitted, the first of them on other needles than those knitting-in the rubber thread, and the next ones in a contrary needle distribution.

3. A method of knitting a terminal course of an elastic welt of a sock article which is knitted in the direction from the toe portion- to the welt thereof, substantially as hereinbefore described with reference to the accompanying drawing.

4. A sock article having an elastic welt with terminal courses knitted by a method according to any preceding claim.

As the next step, the second feed is put into operation, wherein yarns P2 and P2' are simultaneously lapped, the third feed being put out of operation and anti-ladder courses being formed in a known manner. Thus the yarns P2 and P2' are lapped, at first into odd needles in order to close the preceding tuck course A and dial sinkers are projected above the even needles and dial loops are formed of yarn P2 which is lapped by a higher positioned guide, the yarn P2' forming a float-plated pattern since the even needles are in their inoperanve positions.In the next revolution the needle distribution is changed so that yarns P2 and P2' are knitted-in by the even needles and the odd needles are in their inoperative positions, the dial sinkers being projected above them and dial loops are again formed of yarn P2, and yarn P2' is again floated.
