  • Patent number: 4253316
    Abstract: A shogging mechanism for use for example in knitting cable pattern on circular knitting machines incorporates a cam on a mounting fixed with respect to one needle bed of the circular knitting machine. Movement of the cam on its mounting causes another needle bed of the circular knitting machine to be relatively displaced to an extent determined by the cam profile. The shogging mechanism cam is preferably rotatable by means of a further cam having a fixed relationship to the cam system of the knitting machine.

  • Patent number: 4069090
    Abstract: The end closure apparatus is incorporated in the cylinder of a circular knitting machine in surrounding relation to tubular knit fabric advancing from the knitting needles. The apparatus includes constricting elements that are operable simultaneously to close radially on the surrounded tube to constrict it into a compact substantially solid mass. Each constricting element is formed with an intermediate slit so that the elements constrict the fabric at two zones with a space therebetween for heat severing and sealing operation of an electrical resistence heating tool that moves in the slits through the mass of fabric between the zones and dwells thereat to complete sealing and form a small disc-like heat set closure core connecting the yarns of the fabric into a closed end both on the severed tube portion and on the tube portion remaining depending from the needles of the machine.

  • Patent number: 4028910
    Abstract: A knitted fabric tube, and more particularly a portion of a garment to be worn on a foot, closed by being constrained into a constricted form without twisting of the fabric tube and retained in the closed state; and also a method and machine for producing such closed fabric tube particularly with the closure formed as part of the procedure in knitting the tube. The closure by constriction is conveniently effected by wrapping a binding thread around the fabric between parts to form plies of a double welt like portion of fabric at the position of the crease or fold of the welt like portion, portions of the binding thread extending each way from the wrapping turns being knitted into the fabric structure.

  • Patent number: 3974663
    Abstract: An arrangement in a circular hosiery machine in which a motion drive device is provided between the needle cylinder and the dial. A program chain advances with each revolution, and a program drum advances intermittently with the action of the chain. A clutch couples and disengages two members of the drive between the cylinder and the dial, and a control of the clutch is made dependent on the program chain. The rotational motion of the dial is interrupted when the members thereof are not required, and an engagement is provided in at least one predetermined relative angular position.
