    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: 5095548
    Abstract: Moisture control characteristics are imparted to the sock of the present invention by body yarn knit in successive courses throughout the leg and foot. A hydrophobic yarn is knit in plated relationship with the body yarn in partial courses extending throughout the sole, and hydrophilic yarn is knit in plated relationship with the body yarn in partial courses extending throughout the instep whereby moisture generated by the foot of the wearer is wicked and transported from the sole and into the instep to be evaporated therefrom. Cut free ends extend from the endmost stitch loops in wales along the juncture of the sole and the instep while cut free ends of the hydrophilic yarn extend from endmost stitch loops in wales along the juncture of the sole and instep so that the endmost stitch loops at opposite ends of the partial courses of the hydrophobic and hydrophilic yarns are formed in adjacent wales and are not knit in plated relationship with each other in the same courses.

  • Patent number: 4898007
    Abstract: An improved sock wherein moisture distribution, wicking, evaporation and other phases of control, as well as stretch and cushioning, are all managed by the sock construction. The toe and heel portions are knit predominately, or entirely, of hydrophilic yarn while the instep portion extending therebetween is knit of hydrophobic yarn so that moisture absorbed from the wearer'foot by the hydrophilic yarn in the toe and heel portions is transferred by wicking action into the hydrophobic yarn in the instep portion to be evaporated therefrom.

  • Patent number: 4589267
    Abstract: A hosiery knitting method and apparatus wherein contoured terry-type heel and toe areas are circularly knit on a four station hosiery machine by arranging one station to knit complete terry courses on all needles and sinkers and arranging the other three stations to knit partial terry courses on only a group of selected successive needles and associated sinkers. To insure proper plating for terry knitting when reintroducing the yarns at the three other stations, a number of needles preceding and succeeding the needles selected to knit are operated to tuck the base yarn to constrain it onto the lower sinker surface.

  • Patent number: 4341096
    Abstract: The triple layer fabric extends throughout at least a substantial portion of the foot portion and provides improved cushioning and moisture-absorbing characteristics thereto. The sock can be knit on a conventional hosiery knitting machine with very little modification being required. The inside and outside fabric layers of the foot are knit of hydrophobic yarn and the intermediate layer is knit at least in part of hydrophilic yarn so that moisture from the foot is wicked through the inner layer and into the intermediate layer where the moisture is absorbed and then wicked and evaporated through the outside layer. The triple layer in the foot of the sock maintains the foot of the wearer in a dry condition and provides cushioning for at least the ball and toes of the foot of the wearer.

  • Patent number: 4341097
    Abstract: A reinforced toe with varying density is provided for hosiery articles such as sheer stockings, pantyhose and the like so that there is no sharply contrasting line of demarcation between the sheer fabric in the foot portion and the reinforced fabric in the toe pocket and while providing full reinforcement in the area of the toe pocket at the ends of the toes where the need is greatest. The reinforced toe is produced by knitting a reinforcing yarn in plated relationship with the body yarn in spaced-apart courses in a first group of courses adjacent the sheer foot and knitting the reinforcing yarn in more closely spaced courses of a second group of courses adjacent the closed end of the toe pocket. This arrangement provides a gradual or stepped transition from the sheer fabric of the foot to the relatively heavy fabric at the closed end of the toe pocket and provides the reinforced toe with varying or increasing fabric density from the foot to the closed end thereof.

  • Patent number: 4277959
    Abstract: The present athletic socks are particularly suitable for jogging and running and are provided with shock absorber cushion pads in the heel (11), ball (15), and in the inner portion (16a) of the arch area (16) and being formed by a sufficiently greater amount of yarn being knit in these portions than the amount of yarn knit in the outer portion of the arch (16b). The shock absorber cushion pads protect and cushion the heel, ball and inner portion of the arch of the wearer's foot and reduce the shock normally imparted to the heel, ball and inner portion of the arch of the foot so that normal articulation of the bones in the feet takes place when the wearer is jogging and running. The shock absorber cushion pads are illustrated as being formed by providing a greater density of terry loops in the heel (11), ball (15), and inner portion (16a) of the arch than in the outer portion (16b) of the arch to enhance the cushioning provided in the corresponding portions of each sock.

  • Patent number: 4162620
    Abstract: In a circular-knit, closed end tubular article, for example, a stocking or a sock, the opposite-lying loops of the linking course at the closing end are successively embraced by a linking thread and are drawn thereby together until their complete closure is aligned, thus forming a linear seam, the end of such articles being closed by laying of the linking thread in selected needles which are alternately operated on the opposite sides of a cylinder; as the thread is being pulled out, it brings together the opposite-lying loops of the linking course until their complete closure is aligned to form the linear seam which is scarcely visible on the article and its appearance resembles a looping seam.
