Abstract: The peripheral fittings for resolving sliver are carried by an annular sleeve. Such sleeve is removably mounted concentrically of the resolving roller shaft by a centering roller body carried by the shaft. A resilient member is radially spread by a clamping ring to frictionally interconnect the roller body and the fittings sleeve for maintaining the sleeve in desired axial relationship and for transmitting force from the shaft and roller body to the peripheral fittings to effect conjoint rotation.

Abstract: Mechanism for supplying sliver to a resolving roller is adaptable to slivers having different average staple fiber lengths by selectively engaging a plurality of clamping members to provide a selectable nip line between a sliver supply roller and its cooperating member at different distances from the resolving roller corresponding to the sliver average staple length. Either the selected clamping member or the counter member is the supply roller. Selection of the desired nip line may be made by moving one or more clamping members and the counter member relatively, by selection of one of a plurality of feed nozzles, or by selective positioning of a movable feed nozzle. The nip line selection may be effected at individual spinning stations or simultaneously for a plurality of spinning stations.

Abstract: A flyer bobbin for receiving roving having an elongated cylindrical barrel with a longitudinal groove provided in the surface thereof. An elongated resilient clamp member is carried within the groove with one end secured in the groove and the other end extending therefrom. A flat area is provided on the surface of the bobbin directly adjacent one end of the groove directly under the outwardly extending portion of the resilient member. A similar resilient clamp member and groove is provided on the opposite side of the barrel. Thus, by using two clamp members, one of them always faces the service side of the machine.

Abstract: A series of roller pairs in the drafting zone of sliver drafting apparatus have toothed or needlelike projections. The projections are spaced circumferentially and axially of the rollers so that projections of cooperating rollers either within a pair or between rollers of adjacent pairs are periodically interdigitated, as seen axially of the rollers, in spaced relationship as the rollers rotate at constant angular velocity. The rollers carry toothed wheels engageable for positive drive without backlash by a toothed belt. The upper rollers of the pairs are driven by a common endless loop belt and the lower rollers by a second belt. Each belt passes over a spring-loaded jockey roller which tensions the belt and which can be moved against the spring force in response to overloading tension on the belt caused by retardation of roller rotation in response to excessive fibres between a roller pair. Such movement of the jockey roller actuates a limit switch to shut off the belt drive motor.

Abstract: A pressure member cooperates with a supply roller to feed sliver to a sliver resolving roller enclosed by a housing. The pressure member has a sliding surface shaped complementally with and overlapping a sliding surface on the resolving roller housing surrounding the sliver infeed opening in the housing. The sliding surfaces cooperate to seal the resolving roller housing against gaps and maintain a smooth-walled roller chamber in any adjusted position of the pressure member.The interior wall of the housing chamber enclosing the resolving roller may have a thin liner bonded to it. The liner is of material capable of being formed to fit a non-cylindrical wall and of providing a precisely smooth wear-resistant surface. The liner has sliver infeed, fiber discharge and, optionally, dirt discharge openings through it aligned with corresponding openings in the housing wall; but the liner openings are smaller than the housing openings and, therefore, extend beyond and shield the edges of the housing openings.

Abstract: Transmission of the thread twist-forming force to the thread end is facilitated by a finger mounted eccentrically in the bore of the thread drawoff tube. The thread, which is rotated about the circumference of the bore, periodically engages the finger, which finger plucks the thread away from the tube wall and momentarily relieves the bearing force between the thread and the drawoff tube at the tube infeed end. The finger is spaced inwardly from the tube infeed end and may be a pin projecting radially inward from the tube wall or an offset wire extending parallel to but eccentrically of the tube axis.

Abstract: A thread-control tool has a notch for receiving a yarn stretch and holding it between the jaws of a cutter having a fixed blade and a movable blade on one arm of a bell crank. When a full spool is removed, the supply yarn stretch is seized by a thread-holding notch in the tool, the thread is severed, and the supply stretch severed end is fed to a suction port to be held and tensioned while the full spool is exchanged for an empty spool core. The thread-control tool then seizes the thread stretch adjacent to the suction port and carries the thread to one end of the empty spool. A wedging element on the tool wedges apart the spool end and its end-supporting plate to form a slot and to insert a portion of the supply stretch into the slot. As the wedge is moved out of the slot, the slot closes and the thread is clamped. The thread beyond the clamped portion is severed, and the cut off end portion is carried away through the suction port.

Abstract: One end of the housing for a spinning turbine is closed by a cover adjacent to the spinning cup mouth, which cover is connected with sliver-supply and yarn drawoff apparatus. The other housing end portion encircles a sleeve having bearings for the spinning cup shaft. Such shaft may be connected to drive means such as a belt or a commutatorless direct current motor, which drive means can be quickly disconnected. The sleeve-encircling housing portion includes quickly-releasable means for releasing the bearing sleeve for removal either alone or with attached drive means, and for replacement by a substitute bearing unit. The housing may have a longitudinal slit through a portion of its wall and cooperating lugs on each side of the slit for receiving nut and bolt means to clamp the split housing around the bearing sleeve. Alternatively, a set screw extends through the housing wall and bears on the sleeve to prevent sleeve movement.

Abstract: Free flight magnetizable selector elements are transferable from a selector element store disc to a selector element support disc for selecting particular ones of a series of textile processing implements in response to a program. The discs are disposed with an arcuate portion of one disc closely adjacent to an arcuate portion of the other disc, and the selector elements are transferred from store disc sockets to support disc sockets and vice versa by a transfer magnet. The discs include magnets with opposite polarity to maintain transferred selector elements in the sockets of the selected disc until the transfer magnet effects another transfer. The sockets of the store means and support means have the same pitch as the textile implements; however, the sockets of the entire support means may be distributed among a set of identical superjacent discs each having a socket pitch an integer multiple of the textile processing implement pitch. The store means has a corresponding set of superjacent discs.

Abstract: A method and apparatus for loosening and spreading textile tows comprised of bundles of synthetic filaments preparatory to cutting into staple fiber is illustrated including tensioning the tow in a stretching zone while intermittently exerting a force thereon transverse to the direction of movement of the tow.

Abstract: Fibers are carried to a spinning rotor from a fiber-resolving device by a translational fluid medium, such as air, which is first accelerated to orient the fibers. Carrier fluid next is maintained at constant speed and laminar flow to deliver the oriented fibers to a rotating laminar fluid in the region adjacent to the inner wall of the spinning rotor. The acceleration and velocity of the translational fluid is effected by a feed tube having a frustoconical infeed section, tapered toward a cylindrical outfeed section.

Abstract: A device for removing and collecting together a fiber web emerging from a card or the like comprises power driven transport means placed immediately downstream in the direction of travel of the web from the delivery device, and constituting a transport surface crossing the plane of the fiber web and adapted to produce a transport movement of the fiber web material emerging from the delivery device across the width of the web toward the center forming a sliver.

Abstract: When spinning is to be started or restarted after interruption, an operator places a combination spool support and electronic pack on tracks at the spinning station, locates the pack in spool-supporting position, electrically connects the pack with a spinning station connection, draws a predetermined length of thread from the takeup spool, inserts it into the drawoff tube, and actuates a switch on the pack. The pack contains an electronic timing circuit, which sequentially effects starting of the fiber supply to the spinning chamber, and, after a predetermined time delay, effects reengagement of the thread takeup spool with its drive roller.

Abstract: A method and apparatus for producing staple fibers of a predetermined length from a substantially endless tow of fibers. The tow of fibers is fed onto needles carried in rows on a carrier under tension. The carrier is rotated past a cutting area and a depositing area. As the rows of needles pass the cutting area the tow of fibers is raised away from the surface of the carrier to enable cutting of the fibers by a cutter blade. The cut fibers are held by the needles until such reach the depositing area wherein the particular row of needles is retracted to deposit the cut fibers on a receiving means.
