  • Patent number: 7059156
    Abstract: When knitting the sole section and instep section of the toe section, knitting is performed while sequentially decreasing the number of stitches on the small-toe side of the toes by a specified number, and after the number of stitches on the large-toe side has been decreased by a ratio larger than the ratio of decreasing the number of stitches on the small-toe side, the number is increased by the same ratio, and by doing this, on the small-toe side, the side edge section goes toward the tip end and deviates to the inside at a specified ratio, and on the large-toe side, side edge section is nearly a straight line toward the tip end, and by doing this, the shape of the tip end of the toe section protrudes such that it gradually extends to the front of the toes going from the small-toe side to the large-toe side, and that shape is such that it runs along the curve that is obtained by connecting the tip ends of the toes.

  • Patent number: 5211035
    Abstract: A method of making a sock especially adapted for use as a ski sock. The sock is designed to avoid sock pull down or drag down problems by utilizing a stabilizing band of elastic yarn knit in plated relationship with the body yarn and extending around the apex of the heel. The method of manufacturing this split-heel construction uses a circular hosiery knitting machine having short, medium and long butt needles. The needles are selectively lifted out of and dropped in to the knitting track of the machine to form the desired split-heel which prevents sock ride down.

  • Patent number: 5170646
    Abstract: The tubular knit product with a pocket and a method for forming the pocket using reciprocating motion in tubular knit hosiery manufacturing. The method uses a circular knitting machine fed by a plurality of yarn feeds which all participate in the formation of the pocket by a reciprocating motion. During the reciprocating motion, part rows of stitches from yarns of the various feeds are formed in a sequence on a course. For the next preceding opposite course, the part rows of stitches from the yarns of the various feeds are formed in a sequence which is opposite. For each subsequent course, the sequence is opposite to the preceding course, and the course direction is opposite (reversed). On each successive reversed course, the yarns of the various feeds form rows which progressively decrease in a first part of the construction of the pocket and progressively increase in a second part of the construction of the pocket.

  • Patent number: 4887439
    Abstract: The process has: a first step of formation of an elastic border, a second step of formation of a tubular body of knitting starting from the elastic border for a preset number of complete rows, a third step in which a first group of needles and a second group of needles of the machine, which operate on mutually angularly spaced portions of the tubular body, are excluded from working to define a pair of missing portions which constitute the leg apertures of the briefs; the needles excluded from working gradually increase in number for a widening of the missing portions. In the second step, during the knitting of the last complete rows of the tubular body, a preset number of needles, which operate in the mutually angularly spaced regions, and, in the third step, a preset number of needles proximate to the first group and to the second group of needles, are fed with yarn and with elastic thread for the formation of an elastic border around the leg apertures.

  • Patent number: 4541253
    Abstract: Procedure for knitting hose with a toe and heel in a circular knitting machine having more than one feed and two needle cylinders. All needles are brought to an upper path during knitting of the toe and heel with alternating motion, and at every oscillation of the cylinder those needles alone which have been selected to knit the course relative to the oscillation are brought back to work from the upper path towards a lower working path. The selection of needles is brought about by cooperation between fixed radial cams situated so as to correspond with the main feed and appropriate selection actuators. The selection for jacquard designs takes place upwardly from the lower path to the upper path by cooperation between appropriate selection actuators and movable radial cams located so as to correspond with each feed. The upper path serves to exclude the needles of the lower cylinder from work and also to protect the upper cylinder needles, the lower path being the path for jacquard designs.

    Abstract: A circular dial and cylinder knitting machine equipped for the forming of pouches with reciprocating motion with inclusion and exclusion pickers. The machine includes in combination: descent cams for needle butts and descent cams for selection jacks at each feed; cams for the raising of the selection jacks (and thus of the needles) for each feed. The raising cams are at different levels to act on butts at these different levels in the selection jacks and remain fixed during the forming of the pouches. The selection jacks include, for the forming of the pouches with a reciprocating motion and with several feeds, butts at a first level coincident with the entire arc of needles arranged for the forming of the pouch and butts at additional levels on smaller arcs offset from one another. The exclusion and inclusion pickers act on the first level of the jacks butts. The dial and cylinder needles can cooperate to form rib fabric with loop transfer. The loop transfer location can be proximate an active yarn feed.
