Definitions

  • This invention relates to the knitting of elasticated bands, particularly elasticated hosiery tops, on a double cylinder knitting machine.
  • German OS 1 560 993 discloses a technique wherein the body of a sock or stocking is produced by knitting successive courses of ground yarn supplied from a first feed and elastic or elastomeric yarn supplied from a second feed. Whereas the needles of both cylinders are employed in the knitting of the ground yarn, the needles of only one cylinder are used to knit the elastic or elastomeric yarn while the needles of the other cylinder are floated.
  • this technique could in principle be applied to the knitting of elasticated hosiery tops in order to overcome the problems and disadvantages mentioned above, further steps are needed to ensure that the hosiery top has the required stretchability in both the course wise and the walewise directions.
  • such a method comprises the steps of:
  • a further course of elastic or elastomeric yarn is knitted in between each said course of elastic or elastomeric yarn and the succeeding course of ground yarn.
  • said elastic or elastomeric yarn is supplied from a second feed during knitting of the elasticated band, and a further course of elastic or elastomeric yarn supplied from a third feed is knitted in between each course of elastic or elastomeric yarn from the second feed and the succeeding course of ground yarn.
  • said elastic or elastomeric yarn is supplied from a third feed during knitting of the elasticated band, and a further course of elastic or elastomeric yarn from a second feed is knitted in between each course of elastic or elastomeric yarn from the third feed and the succeeding course of ground yarn.
  • Such knitting in of each said further course can be performed using the needles of both cylinders, or using the needles of said other cylinder while floating the needles of said one cylinder.
  • the elasticated top shown in Figure 1 comprises a roll welt 10 and an elasticated band 11, and is knitted on a three-feed double cylinder knitting machine in the following manner. Initially, selected needles are transferred from the bottom cylinder to the top cylinder of the knitting machine, in this case to produce 1 x 1 rib knitting although any other suitable knitting stitch can be used. In order to produce the welt 10, the needles of both cylinders are selected to knit at a first feed of the knitting machine from which ground yarn G is supplied, and a single course 12 of 1 x 1 rib fabric is knitted from the ground yarn.
  • the needles of the top cylinder are then selected to hold loops of the course 12 while the needles of the bottom cylinder knit at the first feed and also at a second feed from which elastic or elastomeric yarn E2 is now supplied, such that alternate courses of the ground yarn G and the elastic or elastomeric yarn E2 are produced.
  • six such courses are knitted.
  • the resultant roll welt 10 is clean, round and has good stretchability in both the coursewise and walewise directions.
  • the needles of both cylinders are selected to knit at the first feed from which the ground yarn G is still supplied.
  • the needles of the top cylinder are selected to knit while the needles of the bottom cylinder are floated, such that loops of the ground yarn are carried through to a third feed of the knitting machine.
  • Such floating of the bottom cylinder needles is achieved on a Bentley Komet machine, for example, by withdrawing the no. 1 upthrow bolt cam.
  • Elastic or elastomeric yarn E3 is now supplied from the third feed, and the needles of both cylinders are selected to knit at the third feed so that the yarn E3 is knitted in alternate wales with the ground yarn loops carried through from the first feed and the loops of the yarn E2 produced at the second feed.
  • successive courses are produced from the ground yarn G, the elastic or elastomeric yarn E2 and the elastic or elastomeric yarn E3, the courses of the yarn E2 having float loops 13.
  • This arrangement gives the elasticated band 11 good coursewise and walewise stretchability.
  • the elasticated band 11 includes about 24 courses knitted in the above-described manner.
  • the desired yarns for the remainder of the article to be knitted e.g. a sock
  • the desired yarns for the remainder of the article to be knitted are selected at the second and third feeds, and knitting of the article is completed in the usual manner.
  • the ground yarn G is typically crimped nylon or a wool/nylon mixture and the elastic or elasticated yarns E2 and E3 are typically composed of a 310 denier core covered with 2/78/20 nylon.
  • the elasticated top shown in Figure 2 is knitted on a three-feed double cylinder knitting machine and is composed of a roll welt 10 and an elasticated band 11. Initially, selected ones of the needles are transferred from the bottom cylinder to the top cylinder of the knitting machine so as to produce a desired knitting stitch, such as the 1 x 1 rib knitting illustrated.
  • the roll welt 10 is then knitted in exactly the same manner as described above with reference to Figure 1, with ground yarn G being supplied at a first feed of the machine and elastic or elastomeric yarn E2 at a second feed thereof.
  • the needles of both cylinders are selected to knit at the first feed from which the ground yarn G is still supplied.
  • the needles of the top cylinder are selected to knit while the needles of the bottom cylinder are floated such that loops of ground yarn are carried through to a third feed of the knitting machine where an elastic or elastomeric yarn E3 is supplied.
  • the needles of the bottom cylinder are selected to knit while the needles of the top cylinder are floated so that loops of the yarn E2 are carried to the first feed of the knitting machine.
  • the elasticated band 11 good coursewise and walewise stretchability with more rigidity and greater elastic force than the elasticated top described above with reference to Figure 1.
  • the elasticated band 11 includes about 28 courses knitted in the above-described manner.
  • the courses of elastic or elastomeric yarn in the welt 10 are knitted at the third feed rather than the second feed, and the latter is brought into operation for the first time when knitting of the elasticated band 11 commences, otherwise, knitting of the elasticated hosiery top is performed in an identical manner to that described above.
  • Figure 3 shows a similar elasticated hosiery top knitted on a two-feed double cylinder machine.
  • the roll welt is produced in exactly the same manner as described above with reference to Figure 1.
  • the courses of elastic or elastomeric yarn E3 are omitted due to the absence of the third feed, and the loops of the ground yarn G are now carried past the second feed for knitting into the next succeeding course of ground yarn when they reach the first feed once again.
  • the bottom cylinder needles are floated past the second feed such that the elastic or elastomeric yarn E2 is knitted only by the top cylinder needles.
  • the elasticated hosiery top shown in Figure 3 can be knitted on a three-feed machine if one feed is unused, the elastic or elastomeric yarn being supplied from either of the second and third feeds.
  • a method of producing a pair of knitted tights utilising the above-described elasticated top will now be described with reference to Figures 4 to 6.
  • a pair of stocking legs 20 are first knitted on a double cylinder knitting machine, each leg 20 being provided with an elasticated top produced by any of the above-described methods and comprising an elasticated welt 21 and an elasticated band 22 adjacent the welt.
  • Each leg 20 is then cut walewise from the welt 21 and through the band 22, as indicated at 23 in Figure 3.
  • the legs are then joined together at the cuts 23 while a knitted gusset 24 is inserted therebetween, the gusset 24 being of such a form that it does not extend into the elasticated bands 22.
  • a preferred shape of gusset is illustrated in Figure 4, although other shapes can be used.
  • the bands 22 together form a continuous elasticated waistband and the welts 21 together form a continuous elasticated welt neither of which are interrupted by the gusset 24.
  • the elastic or elastomeric yarn produces a degree of both walewise and coursewise stretchability which is rather greater than that produced by the elastic ring or elastic material conventionally used for the waistband.
  • the knitting operation can be arranged to produce a break in the ribbing where the cuts 23 are to be made.
