  • Patent number: 4019349
    Abstract: An electronically controlled multifeed circular knitting machine having an electromagnet needle selector in each knitting feed system. A matrix is provided for storing the operating pattern of the needles with respect to the formation of loops in each wale and course, and a reading device for activating the matrix in dependence on the position of the needles. The reading device includes a counter for determining the passage of the needles determining and successively feeding to the input of the matrix data as to the specific needle located at each electromagnet. The output of the matrix is fed to a sweep circuit connected to the electromagnet associated with the respective feed system for each data input.

  • Patent number: 4030279
    Abstract: High-speed spindle holder suspension in textile machines, particularly open-end spinning machines. The suspension includes a sleeve and a pin; between the contact surfaces of the sleeve and the pin there is mounted a resilient damping element made of low density polyethylene. Preferably the low density polyethylene has a molecular weight of about 106 and a hardness of 60 to 80 on the Shore durometer scale.

  • Patent number: 4014189
    Abstract: A hose knitwork such as stockings, socks and the like having a closed toe portion. The closed toe portion is made in the form of a pocket closed substantially at its central section by a wrapping yarn. The toe portion is knit on a circular knitting machine with a combination of loop wales of which certain of the wales have a higher number of loops while the other wales have a lesser number of loops in the same course length. The wales having a lower number of loops may be regularly alternated with those wales having a higher number of loops. The wales having a higher number of loops may be provided with regularly alternating loops of elastic and non-elastic yarns while the wales having fewer loops may be formed with non-elastic yarns. The combination of loop wales may be provided by providing certain of the wales with loops formed of elastic yarn while the other wales are formed with loops formed of non-elastic yarns.

  • Patent number: 4003411
    Abstract: Device for withdrawing fabrics from looms, particularly hydraulic jet looms. The loom has a hauling beam and at least two pressure beams, brackets carrying the pressure beams being mounted by means of eccentrics on the journals of the hauling beams. At least one of the pressure beams may be mounted on the brackets by means of further eccentrics.

  • Patent number: 3986371
    Abstract: A method for forming loops on a circular knitting machine having a plurality of needles and sinkers alternately arranged in cooperation with each other. The sinkers are supported on a rotatable ring located exterior of said cylinder, and have a yarn engaging edge extending perpendicular to the needles and a heel at its opposite end. The steps comprising feeding a yarn to the needles, while sequentially moving the needles downwardly within the cylinder to draw the yarn. Simultaneously engaging the sinkers at their heel ends and advancing each of the sinkers toward an associated pair of needles along a straight line direction at an acute angle to the needles synchronously as the needles move downwardly. Thereby the yarn engaging edge is moved vertically upwardly while the edge is maintained perpendicular to said needles. The edge thus engages the yarn and cooperates with the associate needles to form loops from the yarn simultaneously on the associated needles and sinker.

  • Patent number: 3986329
    Abstract: An open end spinning device having a rotating chamber to which discrete fibers are fed and in which the fibers are spun into a continuous yarn which is removed from the chamber. The fibers are supplied through a duct formed in a parallelpiped body, which duct is directed at the opening of the spinning chamber. The fibers are engaged and deflected with respect to the direction of rotation of the spinning chamber by means interposed between the duct and the chamber so that each fiber is braked at its rear end and caused to enter the chamber in an elongated fashion oriented with respect to each of the other fibers.

  • Patent number: 3977443
    Abstract: The pistons of all pumps in a group which supply pressure liquid to respective jet weft inserting nozzles of a loom are left, after sucking the liquid, in a rest dwell by the action of counterpressure of the sucked-in liquid. Thereafter, at the proper time the delivering space of a chosen pump is connected to its respective nozzle. The rest dwell of the piston in said pump is renewed by its following forcing-down in its suction stroke with its delivery space closed.

  • Patent number: 3977441
    Abstract: Device for recording weaving faults in fabric being manufactured on weaving machines in which a recording card is fixed to a drum means and has associated therewith writing means that are initiated through an electro-magnet and circuitry connected to at least one stop motion on the stop circuit of the weaving machine.The drum which supports the recording card is rotated at the same speed as the advancing fabric being manufactured on the weaving machine through a transmission coupling the drum to means on the weaving machine such as the withdrawal cylinder.

  • Patent number: 3974665
    Abstract: A magnetically responsive circuit is arranged in the yarn breakage detection portion of a knitting machine for providing a visual indication of yarn breakage and for simultaneously switching the operating state of a drive coil-actuated clutch which feeds yarn into the machine. The drive coil is serially connected with a magnetically actuated reed switch which responds to the detection of yarn breakage to switch the operating state of the drive coil. A normally disabled lamp or other illumination device is connected to the drive coil and to the switch by means of a diode. The diode is poled to maintain the lamp disabled while the switch remains unoperated, and to energize the lamp when the switch is operated in response to a detection of yarn breakage.
