摘要:
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.

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.

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.

A device for false-twist texturing of yarn material includes at least three rotatable twisters for disposition around a yarn texturing center, "S"/"Z" twist changeover apparatus for adjusting positions of two of the twisters in relation to a first of the twisters and to transpose the two twisters with each other, and drive changeover apparatus for reversing the rotative drive direction of all of the twisters.

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. The straight-line motion of the loading arms as well as their axial positions holds the yarn being loaded in out of contact with the outwardly traveling rims of one of the sets of disks while pressing it against the inwardly traveling rims of the adjacent set of disks.
摘要:
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.
摘要:
A false twist texturing unit for filaments comprising a motor block arranged in a stationary manner on the machine, stator defined in the motor block, a shaft of the texturing unit including a rotor thereon with the rotor located in the stator and supported and rotatable therin. Various filament monitoring devices, data transmission elements and a filament cutting device, or the like elements, are supported in a stationary manner in the motor block and are thereby protected from distrubances, like those experienced during a repair.

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.
