  • Patent number: 6409955
    Abstract: The present invention relates to a sprue bar assembly for use with a number of different injection molding machines. The sprue bar assembly comprises a fixed sprue bar section having a first channel through which molten material, such as a plastic resin, flows. The first channel communicates with the outlet of a source of the molten material. The sprue bar assembly further comprises an adjustable sprue bar section having a second channel through which molten material flows and a powered unit for holding the adjustable sprue bar section in contact with the fixed sprue bar section so that molten material can flow from the first channel to the second channel without leaking and for changing the length of the sprue bar assembly as needed to accommodate molds of different shutheights.

  • Patent number: 5475909
    Abstract: A yarn entangling device having a housing with an air pressure cushion in it for urging a piston normally outwardly of the housing. The piston has an air passage through it. Shifting the piston outwardly blocks the air passage. A blast nozzle is secured to the piston for being supplied with air through the piston. A baffle plate opposed to the blast nozzle defines a yarn channel. A holder supports the baffle plate for movement away from and into contact with the blast nozzle. With the holder moving the baffle plate toward the blast nozzle, the piston is shifted to open the air passage to the piston, and with the yarn channel opened with the baffle plate away from the blast nozzle, the piston is moved out of the housing by the air pressure cushion cutting off the air flow to the blast nozzle. A closing flap acts through a detent to secure the holder and baffle plate to close the yarn channel.

  • Patent number: 5154365
    Abstract: A bobbin holder for a textile spindle. A spindle having an upper part with opposite double flat surfaces and with a bottom surface. An upper adapter for placement around the upper part of the spindle, the adapter having a recess in it adapted to the shape of the upper part of the spindle, such that at one rotation orientation, the upper part of the spindle core is aligned with and is in the adapter recess and at other rotation orientations, the upper part of the spindle is out of the adapter recess. There is an upper adapter with a conically tapered bobbin receiver and an opposed lower adapter also with a conically tapered bobbin receiver which are both conically tapered to be received in the opening in the bobbin. A spring in one of the top and the bottom adapters biases the respective conical receiver toward the other conical receiver for securing the bobbin between the two conical receivers.

  • Patent number: 5127218
    Abstract: A textile spindle for treating textile or the like, the spindle including a shaft driven by an individual motor. The rotor of the motor is on the shaft. A double row bearing includes an inner ring on the shaft. An outer ring of the bearing is supported in the spindle housing by two axially spaced apart rubber/metal elements. Two additional elastic damping elements attach the spindle housing to a spindle bearing plate. The motor stator is supported in a motor housing attached stationary with the spindle housing.

  • Patent number: 4756150
    Abstract: A mount for spinning spindles which discloses various embodiments of wedge type clamping devices for clamping a sleeve, which is disposed around the spindle housing, securely to a spindle bearing plate. The sleeve surrounds the spindle housing with vibration damping elements between them. The wedge clamping devices are driven by a threaded nut which is tightened up around the sleeve and this clamps the sleeve to the plate. A device for separating the drive belt from the drive whorl of the spindle is attachable on the sleeve and presses the belt off the drive whorl, freeing the spindle so that it may then be unclamped for removal from the spindle bearing plate.

  • Patent number: 4522021
    Abstract: A series of spindles is supported on a rail. A spindle brake is provided acting on a selected one of a pair of spindles which are driven to rotate by a belt. The spindle brake is supported on a holder. The holder is pivoted to the rail. A pair of levers pivotally attached to the holder are respectively pulled for pivoting the holder in one and the opposite directions. A brake element is supported to the holder. The brake element includes a brake surface. Pivoting of the holder pivots the brake element to bring the brake surface into braking engagement with the respective spindle. A belt lift-off roller is pivotally supported to the holder on an axis spaced from the holder axis and is so shaped and placed that pivoting of the holder to brake a particular spindle moves the belt lift-off roller to lift the belt off that particular spindle.

  • Patent number: 4485617
    Abstract: A false-twist apparatus has three parallel shafts carrying interleaved sets of friction disks interconnected by drive belts for joint rotation; one of these shafts is journaled in a stationary mounting plate while the others are journaled in a carrier pivotally connected with that plate for swinging about a fulcrum offset from the three shaft axes whereby two of the disk sets can be separated to facilitate the introduction of a yarn into the intervening twisting region. A whorl on the carrier-supported shaft nearest the fulcrum is normally driven by frictional contact with a continuously moving tangential belt but is disengaged from that belt in the swung-out position of the carrier so that the disks are arrested during introduction of the yarn.

  • Patent number: 4445320
    Abstract: A spindle brake for a spinning or twisting machine has a pair of arms whose jaws are engageable with the whorl of a spinning or twisting spindle. One of these arms carries a belt-lifting roller adapted to lift the belt away from the whorl when the brake is actuated thereby preventing friction between the belt and the immobilized whorl.

  • Patent number: 4442664
    Abstract: A false twist device has a pair of fixedly positioned spindles whose whorls are driven by a tangential belt and whose friction discs overlap wtih each other and with the friction discs of a swingable spindle mounted on an arm which can be angularly displaced about a pivot axis parallel to the spindle axis but spaced outwardly from the triangle defined by the axes of the spindles.

  • Patent number: 4226080
    Abstract: A false-twist apparatus has a support defining three generally parallel and radially spaced axes surrounding a central axially extending twisting region. Respective shafts are journaled in this support for rotation about the axes and carry respective staggered sets of axially spaced disks whose rims radially overlap at the twisting region. Yarn eyes above and below the sets of disks are axially aligned with this twisting region so that a yarn to be false-twisted can pass axially through the lower eye, then zigzag along the regions in contact with the disks, and then pass axially out through the other eye. All of the disks are permanently joined and synchronously rotated. A holder displaceable in a straight line on the apparatus support carries a plurality of arms having yarn-pushing tips that can push a yarn to be false-twisted radially into the region.
