Abstract

The invention relates to a tubular knitted article such as a sock and a method of its production. The invention solves the problem of most simple fashioning of the heel pouch by rotary knitting, which is substantially achieved in that between complete courses (A, P6) there are partial courses of three lengths, out of which one course (P3) is the longest, two courses (P2, P5) are shorter and two courses (P1, P4) are the shortest. The ends of the partial course are secured by tuck stitches. <IMAGE>

Description

SPECIFICATION Tubular knitted article and method of its production The invention relates to a tubular knitted article such as a sock and the like with rotary knitted heel or toe pouch, which is formed of complete and partial courses.

A method of production of a heel pouch in rotary way on a circular six-feed machine is known, said method consisting in the following procedure. The first and the fourth knitting feeds knit in the zone of the heel always complete courses, i.e. they knit on the arcs of the needles equalling 360". The third and the sixth knitting feeds knit partial courses on the smallest arc of needles, e.g. 100 . The second and the fifth feeds then knit in each revolution on different numbers of needles always higher than the third and the sixth knitting feeds.

During the first half of the heel in the second and fifth knitting feeds the needles are added and in the second half the needles are castoff.

Said solution of the pouch heel has the disadvantage that for socks the heel pouch is less clean, because the ratio of the numbers of stitch courses in the heel to the number of the stitch courses in the instep is only 3:1.

Another disadvantage is that the second and the fifth knitting feeds must be provided with a patterning device to select differently long arcs of needles in each revolution of the needle cylinder.

The purpose of the invention is to eliminate the above mentioned disadvantages.

According to one aspect of the invention there is provided a tubular knitted article such as sock and the like with a rotary knitted heel or toe pouch which is formed of complete and partial courses, wherein between complete courses there are partial courses of three lengths, of which one course is the longest, two courses are shorter and two courses are the shortest.

According to another aspect of the invention there is provided a method of production of a rotary knitted pouch in the above tubular knitted article, wherein after knitting the leg portion of the article there are between the complete courses gradually one after the other knitted first the shortest, then the shorter and then the longest partial courses and then the shortest and the shorter partial courses.

The invention permits in the area of the heel several times higher number of stitch courses than in the instep, while mutual combination and sequence of lengths of partial courses permits or secures safe knitting-in of the free ends, which is one of the big problems in the pouches formed of partial courses. The machine does not need to be provided with a patterning device, while this method is especially advantageous for a six feed machine.

An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a schematic connection of individual partial courses between two complete courses; and Figure 2 illustrates schematically the heel pouch in the fabric.

In a known six-feed single-cylinder circular knitting machine the articles are knitted only in rotary knitting, while a pouch is formed in the heel by means of partial courses which are knitted between complete courses passing over the instep as follows. First a known, not shown welt is knitted and then the leg portion 1 (Fig. 2) which ends in the last complete course A, which is knitted on all needles of the needle cylinder in the sixth knitting feed.

During the next phase of knitting the first knitting feed knits only on an incomplete number of needles and that in the zone of 100" and the first partial course P1 is formed, following after the complete course A, as illustrated in Fig. 1. The beginning and the end of said partial course P1 is secured by tuck stitches in the zones X1 and Y1. In the other, i.e. in the second knitting feed a larger arc of needles knit, that is the arc of 140 and partial course P2 is knitted, the beginning and the end of which is secured by tuck stitches in the zones X2 and Y2, which follow after the course A.The third knitting feed knits on the largest arc of needles that is on 1800 and partial course P3 is knitted, the beginning and the end of which is again secured by tuck stitches in the zones X3 and Y3, which follow again after the course A. The fourth knitting feed knits on the smallest arc of needles, 100 , partial courses P4, which is secured by tuck stitches in the zones X4 and Y4 in partial course P3. The fifth knitting feed knits on the arc of needles of 140 while the securing zones X5 and Y5 of the tuck stitches follow after the partial course P3. The sixth knitting feed knits on all needles in the needle cylinder and forms a complete course P6 and the whole sequence of knitting is repeated, so that in the heel portion between complete courses there are partial courses of three lengths and in the instep portion only complete courses, as illustrated in Fig. 2. The securing zones of tuck stitches follow always after the plain stitches of the preceding course, so that there is not more than one tuck loop on the needle. After the end of after knitting a satisfactory number of courses in the heel, the foot and the instep are knitted on all needles. In the toe of the fabric it is possible to knit in the same way as in the heel.

Within the scope of the invention it is possible to change the operating arcs of needles with regard to the type of the article and to the diameter of the needle cylinder.
