摘要:
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.

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. In a preferred embodiment of the present invention, the fixed sprue bar section and the adjustable sprue bar section are each provided with a valve gate for preventing drooling or leakage of the molten material when the two sections are separated.

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 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 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.

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.
