Abstract: In a bale plucking machine wherein a fiber bale is reciprocally displaced between a pair of displacement terminals by a pair of conveyer means disposed with an intervening space therebetween and fiber tufts are continuously plucked from the fiber bale by a plucking roller when the fiber bale passes over the plucking roller, a method and device for supplying a fresh fiber bale on the conveyer means. When the thickness of the processing fiber bale has been reduced to a predetermined limit, the processing fiber bale is displaced to a waiting position formed on an extended portion of one of the conveyer means outside the terminal of the reciprocal displacement thereof, and the conveyer means are stopped. Thereafter a fresh fiber bale is supplied onto the processing fiber bale reserved at the waiting position. During the above-mentioned supply motion, the driving of the conveyer means is again commenced.

Abstract: A textile sliver is fed through a tube and into a drum to coil therein, and the tube and drum are relatively rotated about an axis; the tube extends at an angle to the axis to deliver the sliver to coil within the drum; the sliver has a static charge as it enters the tube, and the method includes the steps:A. imparting to the tube inner wall a static charge of a polarity the same as said charge on the sliver thereby to effect a repulsion of the sliver from said inner wall, andB. continuing said feeding of the sliver through said tube as the tube rotates about said axis.

Abstract: Apparatus in a card for sensing and controlling the relative speeds of the feed and doffer rolls in accordance with the sliver density. A mechanical sensing device responds to the cross-section of the sliver to close the contacts of an electrical circuit when the cross-section deviates from an acceptable range. On contact closure, the circuit provides an electrical signal to the drive arrangement of the feed and doffer rolls to vary the roll speeds thereby effecting a correction in sliver cross-section.

Abstract: A method for forming discrete fibrous pads including the steps of entraining fibers in air to form an air-suspension of fibers and directing the suspension selectively to different predetermined regions of a pad-formation assembly to form discrete fibrous pads on the assembly.

Abstract: In this machine, tufts of fibers are delivered from a feed section by an air bridge into a generally vertical chute past a rotary feeder condenser on which the fibers are formed into a mat which is carried onto a feed plate over which the mat is fed by a feed roller into a lickerin rotating at high speed. The lickerin, which is vertically below the condenser, combs fibers from the mat. The fibers are doffed from the lickerin through centrifugal force and by an air stream flowing past the lickerin. The air stream conveys the fibers through a generally vertical duct to an endless belt screen condenser on which they are deposited to form the random fiber web. The air is recirculated past the lickerin to aid in doffing the fibers from the lickerin.

Abstract: A method of combing textile and the like fibers is provided in which the free end or fringe of a sliver of fibers is clamped, a section of the sliver adjacent the clamped fringe is combed leaving the fringe itself uncombed. Thereafter the clamp is released and the fringe of the sliver is combed. After fringe-combing, the fibers which have been combed by these two operations are drawn off from the sliver through a comb element to comb the tail ends thereof. Apparatus adapted to carry out the method of combing is provided and includes combing means comprising a clamp for clamping the free end or fringe of a sliver of fibers and a comb element relatively movable with respect to the clamp to effect combing of the sliver adjacent the clamp, means to comb the fringe of the sliver when released from the clamp and means to draw off the thus partly combed fibers through a comb element to comb the tail ends thereof.

Abstract: A safety device for stopping the bale plucking operation of a bale plucker provided with a detecting device for detecting the existence of metallic substances contained in a fiber bale. The detecting device is disposed at a position along a path of reciprocating movement of the fiber bale back and forth over the working position of a plucking roller of the bale plucker and the driving mechanism of the bale plucker is capable of being instantly stopped by a signal issued from the detecting device upon detection of a metallic substance in the fiber bale so that carrying of the fiber bale to the plucking roller can be prevented.

Abstract: A rotary drafting apparatus for use in a spinning machine, which apparatus comprises a pair of back rollers coactively rotatable for guiding therethrough sliver to be drafted, and a pair of front rollers coactively rotatable for drafting the guided sliver. A sliver control mechanism is interposed between the back rollers and the front rollers and includes plural pairs of control rollers, which are rotatably supported through their respective support shafts and which are formed with numerous needles, so that the guided sliver may be combed when it is passed therethrough. A rotation regulating mechanism is also incorporated in the drafting apparatus so as to regulate rotation of that pair of the control rollers, which is positioned closer to the front rollers, substantially at a predetermined constant angular velocity in a manner to be free from being affected by any possible variation in the drafting force of the front rollers, thereby minimizing unevenness in thickness of the sliver obtainable.

Abstract: A beater roll for open end spinning is illustrated wherein a coil of metallic wire card clothing has a predetermined set applied therein prior to installation such that the coil assumes an inside diameter less than an outside diameter of a molded plastic drum on which it is installed, the coil being wound in successive contiguous convolutions so that the beater roll is durable, disposable and has a minimized tendency to load with fibers.

Abstract: System for treatment of a tow of fibers which are to be at least partially immersed in a liquid treatment bath, including hold-down bar and tow-guide combinations situated in at least two parallel vertical planes. The tow-guides are inclined with respect to the vertical and to each other. The means for attaching the hold-down bars and tow-guides allows positioning thereof in different positions.

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: A cotton ginning apparatus having a rotating ginning saw drum for engaging and holding the fibers of the seed cotton. A cylinder-like serrated kicker device extends across the path of the seed cotton being admitted for directing the seed cotton onto the ginning saw cylinder. The seed cotton, being held upon the ginning saw cylinder, is brought into engagement with a rotating spiral shaped gin roller. The gin roller has several spiral conveyor-like vanes which respectively have left and right-hand twists thereto that terminate midway between the outer ends thereof. The gin roller rotates with a greater surface velocity than that of the ginning saw cylinder, thus a lateral wiping action acts upon the seed cotton while the teeth of the ginning saw cylinder have a continuous pull on the fibers. The wiping action of the gin roller and the ever present pull on the fibers separates the seeds from the fiber, i.e., the removed seeds being carried inwardly to the center of the gin roller for discharge therefrom.

Abstract: In order to compensate the combing periods in density fluctuation machine slivers, the density of each of a plurality of slivers is measured to detect the phase positions of the combing periods therein and then the relative positions of the respective slivers are adjusted to place the combing periods in each sliver out of phase with the combing periods in the other slivers before the slivers are combined. The adjustment of the phase position of the slivers is effected by varying the length of the path of the sliver between the combing machine and the point where the slivers are combined.

Abstract: The turntable on which the silver can is mounted is connected to a piston of a compressed air cylinder and air pressure is used to maintain the piston and table in preset positions. When the silver can is filled to the preset weight, the table and piston move downwardly to activate either a switch in the path of the piston or a pressure responsive switch in the air line to the pressure side of the air cylinder.

Abstract: A fiber retrieving apparatus is incorporated into the upper wall of an enclosure mounted beneath the lickerin. A suction outlet in the lower wall of the housing is connected to a source of suction for continuously removing trash, motes, fly, short fibers and the like collected therein. An air inlet is provided in either the front wall or rear wall or both to replace the air removed from the housing so that good fibers are not drawn from the lickerin roll.

Abstract: An unpredictable random distribution of segments of supplemental strands of fiber are produced in a base strand by pulling segments from the supplemental strands and adding them to the base strand. The segments are pulled from free extents of the supplemental strands that have a free length longer than the length of the fibers of the supplemental strands, and the supplemental strands advance slower than the base strand, with the result that the size and occurrence of the pulled segments in the base strand are unpredictably random. Preferably, a draw frame is used, to which is added a feed unit having a pair of rotating feed rolls for feeding the supplemental strands to the next-to-last pair of drafting rolls that have a surface speed greater than the feed rolls and are spaced therefrom a distance greater than the length of fibers in the supplemental strands.

Abstract: A fiber web for use in the manufacture of slub or jaspe yarn is produced by a modification of a carding engine whereby a final fancy roller is mounted on a controllably movable support for movement towards and away from the surface of the carding drum, thereby varying the thickness of the sliver obtained before the sliver enters the doffing cylinder. The movement of the fancy roller may be controlled by a programme carried on an endless tape.

Abstract: Apparatus and method for removing fibers from fiber-laden pallets is disclosed in which the bulk of fibers is removed in a primary unloading area thus leaving a thin layer of fibers that are removed by a surface cleaning device. The surface cleaning device included a multiple-blade rotary sweeper which is spaced vertically above the uppermost portion of a pallet to enable the pallet to move therebelow without mechanical interference with the rotary sweeper. A cowling encloses a portion of the periphery of the rotary sweeper to increase the efficacy of fiber removal by the rotary sweeper. The rotary sweeper mechanically engages an upper portion of the thin layer and removes it from the pallet. A suitable gas blast device impinges upon the pallet surface at a location substantially below the rotary sweeper to engage a lower portion of the thin layers of fibers. The gas blast device causes fibers to be lifted upward and into mechanical engagement by the blades of the rotating sweeper.

Abstract: An improved fiber condenser for a spinning frame which is designed to provide an area for the passage of roving which has an elongated opening therein to allow slubs, etc., to pass through without breaking the roving or stretching it.

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.
