KNITTED HOSIERY AND METHOD OF CLOSING THE TOE OF SAME Fild Dec. 1. 1954 INVENTOR. JZMES ,4 $5742.

I B Y D a ATTORNE KNITTED HOSIERY AND METHOD OF CLOSING THE TOE F SAME James L. Getaz, New York, N. Y. Application December 1, 1954, Serial No. 472,4-40 12 Claims. (Cl. 66-187) This invention is related to knitted hosiery and particularly to a novel hosiery construction and to a method of closing the toe of hose which are knitted on circular knitting machines.

As is well known, the manufacture of hosiery is di vided into two basic methods, i. e., full fashioned and circular knit. In the former the hose is knitted flat and after the knitting is completed, the two sides of the hose are folded together and the edges are sewn, with a seam which runs lengthwise of the foot and which extends to the end of the toe. This seam is located onthe bottom of the foot where it is not visible when the hose is worn, and, although it is not a fiat seam, has been found not to cause any discomfort to the wearer. It provides a quick and inexpensive method of closing the toe and is currently used for making most ladies hose.

In the manufacture of circular knit hose, the closing of the toe, according to the method which is now in use, is more diiiicult. The seam instead of running lengthwise of the foot, is across the foot near the toes and is at a right angle to the length of the foot. This seam also extends halfway around the sides of the foot, and, because of its location, must be a flat seam in order to be comfortable to the wearer and acceptable to the trade. To make this scam in a satisfactory manner it is necessary for the operator to place by hand each loop at the end of the toe portion of the hose on one of the points of the dial of a looping machine. The loops of the instep portion are likewise individually placed on the same points as the loops of the foot portion and these pairs of loops are sewn together to close the toe.

This operation of putting the loops on the points of a looper dial is tedious and requires a long period of training on the part of the operator before sufiicient skill can be obtained. in fact, this looping of circular knit hosiery is generally agreed to be the most diiiicult man ual operation presently involved in the commercial manufacture of hosiery.

it is the purpose of this invention to provide a circular knit hose construction wherein the seam which closes the toe, instead of running across the foot, is lengthwise and on the bottom of the foot. In this way the seam is placed in such position that it need; not be a fiat, seam to be comfortable to the wearer, and it may-be made without thetedious manual operation of putting-the loops individually on the points of a looper dial.

In the accompanying drawings:

Figure l is a side view of the hose as it comes from the knitting machine.

United States Patentr O In the manufacture of circular knit hosiery there are two methods of rotating the cylinder which are used in the same hose. In one method, the cylinder runs continuously in one direction, generally counter-clockwise; in the other the cylinder reciprocates back and forth mak- 2,740,279 Pa t d t ing less than a complete revolution in each reciprocal movement. The needles in the cylinder consist of two groups, each containing the same number of needles; those which knit the instep portion have long butts and those which knit the bottom of the foot have short butts.

In making a stocking the knitting begins at the top A (Figure 1) and continues with the cylinder rotating in one direction until the point'B is reached. Then the instep needles which have long butts are raised to a height which puts them out of action, the rotation of the cylinder is changed to reciprocation and knitting proceeds to the point C on the short butt'needles alone. With each reciprocal stroke, one short butt needle at either side of the group is raised by a pick so that it isout of action. This process of successively raising the needles narrows the fabric and forms a gore CD. At point D, only a few needles remain in action. Then the short butt needles which have been raised are put into action one at a time and the ,goreis widened until the line CE is reached, whereupon the knitting of the'heel will have beencompleted. At this point the long butt needles are; brought into action and the knitting proceeds on continuous rotation during the knitting of the foot.

It is customary to knit the toe inexactly the same manner as described above for knitting the heel. There is one exception: in the manufactureof circular knit ladies hose, the short butt needles which knit the' bottom of the foot are raised out of action in the knitting of the toes and the looper seam is on the bottom of the foot to make it less noticeable, however it runs across the bottomjof the foot and shows on both sides, coming halfway up the sides of the foot.

In this invention, the procedure in knitting the toe is quite different. Instead of raising half. of the needles out of action, only a few needles are raised, being those which knit the portion of the foot between the

points

10 and 11 in Figure 2. The reciprocating-movement begins at this point 10 and the are of reciprocation is increased so as to knit a long course from the point 10 past the point 18 and to the point 10 on the other side of the foot. Beginning at 10 a narrowing gore 1013 12 is formed, which is about twice as long as the usual gore, by raising one needle at a time at each side of the group, and as this gore is knitted the instepportion of the, toe is formed from 18 to 12. After the narrowing side of this gore is completed, instead of widening it by putting the raised needles into action, one needle at a time, all the raised needles are put into action at once, then continuous rotation is resumed and the toe portion 13111417 is knitted. When the opening 15-46 has been reached, the hose'is cast from the knitting machine and the seam 17 -41 is. sewn lengthwise of the foot to close the toe. The narrow piece 17'1516-11 is cut off and discarded; The seam 17-11 is shown more clearly in Figure 3, wherein it may be seen to lie in the many variations thereof within thescope of. this invention. After the gore 10-13-42 is completed, instead of putting all of the needles into action at once, they-may be, brought into action one at a time or two at a time. If it is desired to shorten the seam 1.'711. this may be done by incorporating a non-stretchablecord in the seam as it is sewn, or an elastic yarn may be used in the: toe, portion 13-111417. An elastic yarn may be used at the opening 15-16 to take the curl out of the end fabric and facilitate the sewing of seam 17-11. On account of the location of scam 17-11 on the bottom of the foot it is not necessary for it to be a flat seam, but if a flat seam is desired it may be obtained by making the toe portion 13-11-14-17 of nylon and using nylon sewing thread in seam 1 be permanently flattened by pre-boarding the hose with pressure on the seam. Other variations may be developed as this method is put into volume production.
