  • Patent number: 4044574
    Abstract: Closing the toe opening of a stocking, or the end of a tube by providing a two ply welt defining the toe pocket, and constricting the fabric of at least one of said plys about the axis of the toe opening to obstruct the same. The constriction or gathering of the fabric is effected by winding a thread about the fabric. The knitting of the stocking and the welt and the closing of the opening are carried out automatically, as an integrated operation and on a single machine.A stocking, the toe pocket of which is defined by a two ply welt having an end opening, said opening being closed by gathering fabric there-across.

  • Patent number: 3981161
    Abstract: A continuous, tubular, one-piece panty hose is formed on a circular knitting machine with a waist opening extending longitudinally of the direction of knitting and surrounded by a reinforced elastic section with stitches that resist raveling or breakdown. In the waist portion of the panty hose, each course is formed by a pair of partial courses, one end of which overlap and the other end of which form the longitudinal opening.

  • Patent number: 3956909
    Abstract: The body garment is of seamless knit and unitary construction and may comprise a panty or the body portion of tights or panty hose of the one-piece type. The body garment comprises a plurality of panels formed by reciprocal knitting which enables variations to be made in the size of different portions of the body garment according to the walewise and coursewise dimensions of the several panels. These panels comprise two elongated waist panels generally formed with tapered edges and separated by a crotch panel running generally perpendicular thereto. The last complete course on the leg portion of the body garment is parallelly interknitted with the adjacent courses on both the crotch and waist panel sections.

  • Patent number: 3945224
    Abstract: Rotations of a circular knitting machine are counted and encoded into electrical signals. After a prescribed number of revolutions a programmer and program indicating disc signal a switching mechanism to shift a cam drum to the next position in the pattern. A first circuit is provided for operating the needle cylinder at a slower speed during the aforesaid shifting operation, and a second circuit is provided for running the machine at maximum and intermediate speeds during the knitting operation in response to a preselected pattern. The programmer includes two types of output signals for controlling the production of fabric according to type or size.

  • Patent number: 3940954
    Abstract: An electrical supervisory circuit arrangement, as for detecting faults such as yarn breakage in a circular knitting machine, comprises a number of channels each responsive to a particular type of fault signal in the machine. Each channel comprises a bistable transistor circuit which is switched in response to the particular fault condition to be detected and, when so switched, energises a warning light. In addition, all the bistable circuits are connected in common to an output transistor which is thus switched when any of the bistable circuits detects a fault. The output transistor controls two relays, one of which disconnects the forward-current supply to the machine and the other of which temporarily provides a reverse-current supply for braking the motor.

  • Patent number: 3937040
    Abstract: A process for knitting the body portion of a panty or panty hose of one piece construction on a circular knitting machine which comprises knitting a first leg portion by tubular knitting, supporting the tubular knit portion on all the needles while inactivating the needles along a first arc and knitting by reciprocal motion on a second arc of needles to form a first waist portion, casting off the fabric from said second arc of needles, activating the needles along said first arc of needles and knitting by reciprocatory motion to form a crotch panel, inactivating said first arc of needles while supporting the crotch panel thereon, knitting a second waist panel on said second arc of needles, and then knitting on all the needles in a circular motion to form the remainder of the body portion. The dimensions of the waist panels and the dimension of the crotch panel may be changed as desired by varying the number of wales and courses in each panel according to the desired size of the completed garment.
