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.

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.

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.

Abstract: The method for monitoring the operative position data of each of a plurality of independent separately operable knitting machines and transferring such information to the address input of a common memory control system for controlling the patterning of each machine, is obtained by generating a pick-up pulse at each machine indicative of the passage of its needles and of the completion of each course past a given point. A continuous cycle of timing pulses each of which corresponds to a selected knitting machine for which data is to be monitored is provided. In response to each of the individual timing pulses the respective generated pick-up pulses are fed to a logic control sweep circuit, the output of which is fed to one input of an adding circuit. Simultaneously a second input is fed to the adding circuit comprising the position data information of the immediately preceding needle and course, which had been stored in a random access memory unit corresponding to the particularly monitored machine.

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.

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.

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.

Abstract: A circular knitting machine having a patterning means with finite means for storage of a knitting pattern less than the number of needles, and means for controlling the knitting needles in response thereto. Counters for determining the passage of the needles and of the courses of the knitwork from an initial point and a decoder interposed between each counter and the input of the patterning memory to reduce the output of the counters to the capacity of the patterning memory.

Abstract: Method of and apparatus for lateral tensioning or holding of fabrics at a predetermined width. The fabric is formed with at least one auxiliary longitudinal fabric strip joined to the confronting selvedge by uncovered weft threads, the uncovered weft threads being engaged and deflected alternately from above and below in the gap between said strip and the fabric by means of a lever which penetrates between said uncovered weft threads so that, said strip bears against the side of said lever which acts as a temple. Upon further advancement of the fabric the strip is removed from the selvedge thereof.

Abstract: A plurality of knitting machines are controlled from a central control device and a common patterning memory. Each knitting machine is provided with its own needle and course counters in which the needle position is determined. The single control device provides separate clock signals to the counters of each machine so that they may be individually switched to the patterning memory. Simutlaneously, the control device provides means by which the output from the memory is switched to the electromagnet controlling needle operation in synchronism with the needle counter.
