Definitions

  • Stockings of this kind present the advantage that they are very popular with the ladies since the rear seam is lacking.
  • these stockings are knitted in the direction from the welt towards the toe, the circular knitting in the area of the heel and the toe being usually interrupted by oscillatory knitting known as reciprocatory knitting, the required heel and toe shape being obtained by narrowing and widening.
  • Stockings of this kind are also manufactured with a method whereby the machine continues rotary knitting through the heel and toe, and a thermoplastic yarn is used which renders the knitted fabric suitable to be boarded and heat set to a predetermined shape.
  • the invention aims at improving the quality of ladies stockings manufactured on a circular knitting machine by plain or micro-mesh knitting, and knitted in the direction from the welt towards the toe, without the stocking becoming too expensive.
  • the present invention teaches that, in a seamless ladys stocking, above the heel and/ or the toe, an area is knit of runresistant fabric. As a result, a run started in the heel or toe is blocked. Further, by such construction a transition area is provided for safeguarding the stocking above the heel against damages by the edge of a shoe.
  • runresistant knitted fabric extends around only part of the circumference of the stocking.
  • the run-resistant knitted fabric adjacent the toe may extend along the entire circumference, if desired.
  • FIG. 1 a diagrammatical side view of a ladys stocking
  • FIG. 2 a corresponding side view of the lower part of the stocking, in which a preferred embodiment of the invention has been applied;
  • FIG. 3 a view like FIG. 2 showing a modification of the invention
  • FIG. 4 a top plan view of a cam for the sinker ring of a circular knitting machine adapted for practicing the invention
  • FIG. 5 a cross-section according to the line V-V in FIG. 4;
  • FIG. 6 a side view of one of the sinkers of the sinker ring
  • FIG. 7 a perspective view of a stitch cam for controlling the needles of said circular knitting machine.
  • FIG. 8 a side view of a modified sinker.
  • reference numeral 1 denotes the leg of a seamless stocking manufactured on an automatic circular knitting machine, said stocking having been knitted in a direction from the double welt top 2 toward the toe. In doing so, the machine is rotated. in the same direction, except in the areas where the toe 3 and the heel 4 have been formed. In these areas, part of the total number of needles have been rendered inoperative while holding the stitches on said needles, then the needle cylinder is reciprocated, forming the heel and toe while narrowing and widening in the usual manner.
  • the invention teaches (FIG. 2) that an arcuate area 5 of run-resistant fabric is knitted by rotary knitting until the reciprocated heel fabric 4 is commenced. Now if, as a result of friction and chafing by the upper edge of the shoe, a stitch is ruptured in the heel, no run is formed in the leg, as would be the case in known embodiments according to FIG. 1, even if the upper part of the reinforced heel 4 itself remains below the upper edge of the shoe.
  • the stocking may also be improved by having an arcuate area 6 of run-resistant fabric knitted between the toe 3 and the instep 7 by rotary knitting.
  • runs which start in the toe fabric 3 are prevented from passing into the instep 7 by the run-resistant area 6.
  • the rotary knit run-resistant areas 5 and 6 abut the conventionally knit fabric of which the stocking is constructed.
  • Such conventionally knit fabric may be either plain fabric or micro-mesh fabric as previously described.
  • the heel and/or the toe have been .knitted according to the reciprocating method with narrowing and widening. It is possible to apply the invention to stockings which are rotary knitted throughout, and of which the heel and the toe, after having been knitted, are given the required shape by boarding and heat setting to a predetermined shape. Obviously, it is necessary for this purpose to select the correct thermoplastic yarn in the known way. In such case, the heel 4 and toe 3 may be rotary knit of run-resistant fabric.
  • a radially movable sinker cam 10 (FIGS. 4 and 5) to act on the sinkers 13 (FIG. 6).
  • sinkers 13 There are two kinds of sinkers, namely sinkers with a high butt 14 and sinkers with a low butt 15 (see broken line in FIG. 6).
  • the low butt sinkers equal or exceed in number the desired number of sinker Wales in the arcuate areas of run-resistant fabric.
  • the sinkers 13 having a high butt 14 are drawn outward by means of the surface 12 of sinker cam so that the stitch is formed on ledge 17 in FIG. 6.
  • the sinkers 13 having a low butt 15 move along the surface 11 of the cam 10, therefore they are withdrawn less far.
  • the stitch is then formed on ledge 16 in FIG. 6, behind the neb. Since the ledge 16 is located higher than the ledge 17 (FIG. 6), the stitch formed on ledge 16 will be larger than the one formed at 17.
  • the sinker cam 10 is retracted from the needle circle, by conventional linkage means, such as that shown in U.S. Patents Nos. 1,189,220, 2,609,677, 3,104,537 or 3,172,274, or British Patent No. 526,280 or German Patent No. 1,127,- 531. When this is done, all of the stitches are formed on ledges 17.
  • FIG. 8 shows, in addition to the ledges 16 and 17, another two ledges 20, 21, since one is not limited to the aplication of two sinker ledge heights.
  • a preferred fabric for incorporation into the run resistant areas 5, 6, 8 and 9 is disclosed in Nebel et al. US. Patent No. 3,157,037.
  • Such run-resistant fabric consists of plain knit courses alternating with courses composed of alternate tuck loops and knitted stitches, with the plain knit courses containing a shorter length of yarn per course than the courses containing tuck loops.
  • the needle selection necessary to knit such a runresistant fabric is accomplished with the usual pattern drum and pattern jacks, which control the needles through the conventional jacks in the needle cylinder.
  • the special stitch cam shown in FIG. 7 may be provided, having two stitch drawing points, 18 and 19.
  • the conventional latch needles (not shown) are arranged so that selected needles are provided with short butts, and the remaining needles are provided with long butts.
  • the stitch cam is in its advanced position, all needles are drawn down to the stitch point 19, but when the stitch cam is in its retracted position, the short butt needles are drawn down to stitch point 18 and the long butt needles only are drawn down to stitch point 19.
  • the short 7 butt needles will knit a shorter stitch than the needles having a longer butt.
  • the advancement of the stitch cam to its innermost position, and its retraction to its outermost position, is accomplished by the usual mechanism comprising standard equipment for a circular knitting machine.
  • sinker 10 is .retracted so that the yarn is drawn over the ledges 17 of all sinkers. In this fashion, it is possible to knit the arcuate segment of run-resistant fabric from the same yarn from which the conventionally knit fabric is made, and without the addition of a reinforcing or additional yarn.
  • ladys stocking used herein also comprises tights and leotards.
  • a circular knitting machine having a complement of independent needles and sinkers for knitting an arcuate area of run-resistant fabric contiguous to a complementary arcuate area of conventional fabric, with the yarn passing course-wise without interruption from one arcuate area into the other arcuate area, said area of run-resistant fabric having yarn loops in selected courses of a larger size than the yarn loops in the area of conventional fabric, the combination including:
  • each sinker having a neb and two yarn drawing ledges, one ledge being disposed above the other,
