  • Patent number: 4872487
    Abstract: To improve performance and to overcome dangerous problems of overheating in projectile looms, the loom brake has a cooler for dissipating the heat of braking and for reducing local temperature peaks. A coolant is guided in a flow into the vicinity of the braking surfaces. Appropriate cooling facilities can have air nozzles aimed at the braking surface, a liquid circuit supplying coolant to ducts within the brake shoes or tubes in heat-conductive contact with the brake shoes or heat pipes.

  • Patent number: 4865084
    Abstract: The wheel body of a tape wheel possesses two outer half shells which are fastened to the wheel hub. The two outer half shells are arranged in conically inclined relationship to one another with respect to a connecting plane and form a wheel rim by means of annular wall parts. Within the wheel body there may be located an inner stiffening shell which diagonally extends toward the exterior from one flange of the wheel hub to a free end of the other outer half shell. The inner stiffening shell abuts against the annular wall parts by means of an annular shell portion. The transverse or axial stiffness or rigidity of the wheel body and thus of the entire tape wheel is increased in a particularly advantageous manner.

  • Patent number: 4865082
    Abstract: The pacing motion which is adapted to be stepped on in respect of individual wefts has a sliding wedge with a return spring. The wedge is displaceable on an output shaft into a groove of an input shaft in both directions of rotation. The motion also includes a locking lever actuatable off-load by a control signal. The lever locks and unlocks a release lever which is driven by a drive element and actuates the wedge. A transmission with a delay feature or a resilient damping insert can be used as an impact-reducing element to absorb some of the impact of the wedge in the groove. Freely actuatable electromagnets can be used both as actuating elements and as the drive element.

  • Patent number: 4862925
    Abstract: A warp is prepared including a stationary thread, a crossing thread and an auxiliary thread, the latter two of which are laterally interlaced at a sliding connection and subject to being alternately tensioned and released for causing the crossing thread to cross across the stationary thread, and cross back, as conventional loom equipment is manipulated to create a succession of sheds into which wefts are inserted to weave a cross-woven textile fabric. As the weaving is being accomplished, a separating element is provided to prevent the sliding connection of the crossing and auxiliary threads from sliding so far towards the reed as to become incorporated in the fabric. The stationary or auxiliary thread may actually be constituted by a metal or other non-textile element, which is pulled out of the fabric as the fabric, having been woven, is moved downstream on the loom.

  • Patent number: 4862566
    Abstract: An auxiliary device for a seam weaving machine for joining the ends of flat-woven fabrics by a woven seam couples each auxiliary warp thread to a tensioning string. The auxiliary device includes a barbed needle in a guide sleeve with the barbed needle having at one end a barb for seizing an auxiliary warp thread and holding it between the needle and the sleeve. The needle is connected at the other end to a tensioned string. A storage plate is provided having bores for receiving the coupling devices.

  • Patent number: 4854351
    Abstract: The contact bar comprises an outer bar having a U-shaped cross-section and a plurality of bar portions located therein and separated therefrom by an insulating layer. The bar portions are insulated against each other by intermediate insulating layers in partition planes extending laterally as well as parallel to the longitudinal edge. The bar portions are produced suitably by a punching out of a bar such that they, when fitted into each other, will supplement themselves again to a bar such that a shorter bar portion cut proceeding from the upper longitudinal edge of a longer bar portion fits into the longer bar portion. The longer bar portion is at the side facing the end of the contact bar, at which only the connecting contact for a power source is located is considerably narrower than at the opposite side where the drop wires will contact the bar portion upon a yarn breakage.

  • Patent number: 4852617
    Abstract: The weft yarn leaving a drum of a weft yarn store of a loom is monitored by a monitor device disposed between the drum and a yarn eye in the zone of the yarn balloon. The monitor device includes a ring with an internal surface across which the yarn balloon slides during take-off. At least one light transmitter is mounted in the ring to emit a light beam across the path of the yarn and at least one transmitter is also mounted in the ring to receive the light beam for sensing when the yarn passes through the beam.

  • Patent number: 4852618
    Abstract: The yarn selector comprises a number of yarn regulators each adapted to be selectively adjusted by way of a driving member between a standby position and a transfer position in dependence upon an actuator in which transfer position, a weft yarn is presented to a picking element for a subsequent pick. The driving members are selectively engageable with and disengageable from a driver oscillated at the cadence of the picking fequency. Each driving member is adapted to be locked, with the actuator in an active state by way of a ever-arm in an operative position corresponding to the transfer position of the yarn regulator, and to be disengaged from the lever arm with the actuator in a passive state. The particular yarn regulator concerned remains, if the same weft yarn is required for the next pick, in the transfer position after yarn transfer and is returned to the standby position only before a weft yarn change.
