  • Patent number: 7332836
    Abstract: Guide bar drive in a knitting machine and method of driving guide bar. The drive includes a linear motor composed of a stator and a rotor, in which the linear motor is greater in height than width. The stator has a length in a longitudinal direction and includes at least one narrow side, and the rotor is structured and arranged in the stator for translational movement in the longitudinal direction. A guide rod is positioned adjacent the at least one narrow side and extending in the longitudinal direction to support the rotor. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

  • Patent number: 6651420
    Abstract: The new invention proposes that filament yarns, in particular partially stretched yarns known as POY yarns, be subjected to stretch texturing via an air treatment nozzle. The air treatment nozzles are designed in miniaturized form, have a continuous yarn duct in which there open a plurality of transverse bores for the supply of high pressure air in the range over 14 bar, preferably within specific working windows between 20 and 50 bar. With the new invention, it was possible for the first time to process POY yarn via simultaneous stretch texturing using an air twister. The invention allows an individual thread as well as a parallel bundle of threads to be treated and permits for the first time the construction of a false twist stretch texturing bundle device with simultaneous air treatment of 500 to 1000 and more threads.

  • Patent number: 4995246
    Abstract: A warp knitting machine has guide holders, holding arms, and a guide bar assembly. The assembly includes a guide bar made of reinforced synthetic polymeric materials. This guide bar has along substantially its entire length a substantially hollow profile. The guide bar has surrounding walls substantially enclosing the hollow profile. The guide bar includes a first and second segment. The first fastening segment is adapted to be attached to the holding arm. The second fastening segment is adapted to support the guide holders.

  • Patent number: 4528631
    Abstract: In the process for the control of the warp speed during direct warping, the winding diameter is determined by a contactless measurement. The actual thread speed is determined from the winding diameter and the current warp beam rate of rotation. A direct warping machine for carrying out this process has a transducer for measuring the winding diameter. This transducer is located proximate to but not in contact with the circumference of the winding for measuring the winding diameter. Also included is an arrangement for the determination of the rate of rotation of the warp beam. Also, a computer can calculate the thread speed from the above outputs that correspond to winding diameter and rate of rotation.

  • Patent number: 4380913
    Abstract: A weft thread magazine for a warp knitting machine has two endless transfer chains. The chains have holders for retaining weft threads in parallel and presenting them to a needle bed. Also included is a thread laying arrangement which transports the weft threads from one transfer chain to the other, and which is provided with a comb arrangement. The comb arrangement includes a comb element having at least one combing peg which is introduced between the weft threads proximate to one of the transfer chains and which moves parallel to the weft threads and is removed proximate to the other transfer chain. A carriage has a thread guide for guiding at least one weft thread into a position parallel to a previously laid weft thread. The comb element is carried on the end of the carriage directed toward the needle bed.
