  • Patent number: 4805424
    Abstract: A single warp-knitted pile fabric comprising loop courses of ground and pile threads, wherein the loops of the pile threads are run jointly with the ground loops and interconnected by the floats of these loops. Transfers are run on from the pile threads in the same courses as the loops of these pile threads. The floats of the transfers are laid in some courses to overlie the floats of the ground loops, whereas in other courses the floats of the transfers are laid to underlie the floats of the ground loops.

  • Patent number: 4805423
    Abstract: A device for actuating movable cams for use on a flat knitting machine that includes several cams arranged on a cam plate, in which the cams are movable in a direction perpendicular to the plane of movement of the cam box, contains a drum having an axis of rotation that is perpendicular to the plane of movement of the cam box and that is located substantially central relative to all movable cams. The drum includes grooves in the peripheral portion thereof at axial distances from one another, which grooves have variable axial positions over the periphery of the drum. A corresponding engaging part rides in a respective groove and the drum is rotated by a drum mechanism through definite angular amounts so that cams are placed in or out of activity at a stroke of the engaging part in the groove by means of connecting bars assigned to each of the engaging parts riding in the grooves on the drum.

  • Patent number: 4800828
    Abstract: A multiple needle tufting machine incorporating a pair of relatively transversely adjustable front and rear needle bars, each needle bar supporting corresponding front and rear needles in transverse rows for simultaneous penetration of a base fabric moving in a feeding direction through the machine. A looper apparatus is provided incorporating transversely adjustable front and rear loop pile hook bars supporting a plurality of corresponding front and rear loop pile hooks pointing in the direction of fabric feed. Both the front and rear needle bars and the front and rear hook bars are relatively transversely adjustable between positions in which the front and rear needles are in alignment with the direction of fabric feed and a staggered position in which the front and rear needles are transversely offset. Separate yarns of preferably different characteristics are fed to the front needles and to the rear needles preferably by pattern control mechanisms to produce loop pile fabric of various patterns.

  • Patent number: 4799365
    Abstract: The device for monitoring the knitwear (16') of a flatbed knitting machine for falling-off exhibits several support bodies (18) having in each case a feeling lever (17) which rests against the knitwear (16') and which is coupled to a switching arm (25). The switching arm (25) is constructed as a contactless contactor and is moved during an adjusting movement of the feeling lever (17), which is triggered when knitwear (16') has fallen off, through the contact range of an electric switching device, for example a light barrier or an ultrasonic barrier or through a magnetic field area into an ineffective end position so that a control signal can be triggered only during the adjusting movement of the switching arm (25) between its end positions.
