Abstract: A system and method includes a seed roll of a saw type gin stand which can easily be inspected in an efficient and safe manner within the normal course of operation. The monitoring of the seed roll is desirable for prediction of irregularities that could significantly hamper the production of a ginning facility. This monitoring can take place by manual inspection with the eye or touch of the operator. In addition, this feature will facilitate the opportunity to introduce a new automatic process by which the control system can monitor the seed roll in order to improve overall productivity of the gin stand.

The arm and its separation comb (13) are mounted for movement along and controlled by the shape of a separation cam (3) implementing the separation of the fiber web (6) wound on the processing drum (4) at a specified site and the unwinding of the separated fiber web from the processing drum (4) by the free end of the fiber web (6) along a generatrix of the surface of the processing drum (4).

Abstract: A fine heterogeneous hybrid spun yarn is blended from electrostatically conductive staple fibers and electrostatically non-conductive staple fibers so that the yarn is electrostatically conductive only over short discrete lengths. When used in pile fabrics, such as carpets, the fine yarn is introduced with at least some of the carpet facing yarns during the carpet making operations. The resultant carpet structure substantially eliminates electrostatic shock to a human walking across the carpet and approaching a ground such as a light switch, radio, or another person. Such a carpet does not constitute a dangerous floor covering.The unique heterogeneous hybrid spun blended yarn is achieved by process techniques completely contrary to accepted blending practices.

Abstract: A linter gin having improved moting system for achieving higher rates of delinting. The improvement comprising a mote deflector obstacle member spaced slightly from the doffer brush, said member defecting the air current to effect more efficient removal of motes and trash from the lint in the mote chamber.

Abstract: Cotton burrs and other trash from a cotton gin are processed by first passing them over a small screen to remove sand and other fine material. Thereafter, the burrs and other trash are ground in a hammer mill. After grinding, the material passed along a large screen having about 3/8" opening. Substantially all the burrs and trash will pass through the screen except for cotton lint which will not. The burrs and trash, without the lint, is then sized by screening through screens with successively smaller openings. The burrs and trash of any one size is further separated by air classification. The resulting product is a combination of three geometric shapes, fibers, flakes, and granules. The resulting product is a lignocellulose product having softwood lignin precursors.

Abstract: A process and apparatus are provided for manufacturing a fasciated yarn having uniform yarn construction and high strength. The process comprises subjecting fibers to a draft cutting step, at least one amendatory draft cutting step and a yarn formation step wherein the fibers are continuously transferred from the draft cutting step to the yarn formation step without any substantial interruption of fiber movement between the steps.

Abstract: Filler material, particularly for cigarette filters, is produced by feeding a first stream of substantially continuous filaments of filler material onto a pin roller which is driven at a speed such that the filaments are broken by the pins into irregular lengths and are projected from the roller in random orientations. The broken filaments are collected on a carrier stream, also comprising filamentary material, for delivery to a rod-making unit. More than one stream could be supplied to the pin roller so that the broken filaments can comprise a mixture of filaments of different filler materials. The carrier stream may comprise filler material which is different from that in the first stream and may comprise a fibrillated web.

Abstract: A trash by-pass panel is pivoted to the reclamation chute wall in a cotton gin burr and stick machine such that it may be opened to allow heavier trash to be excluded from further processing, thereby increasing the efficiency of the cotton cleaning.

Abstract: The bottom of a lint feeder housing is manufactured such that the high speed belt which it houses is quickly and easily changed. The bottom of the housing is lowered after loosening the four hinged thumb bolts which secure the bottom to the housing. After the bottom is lowered, the axles which support conveyor rollers are lowered a little on one side. The worn belt is removed and a new belt is slipped between the axles and the frame of the housing then over the rollers. Once the new belt is in place, the axles are raised and the bearing housings are fixed to the feed housing. Finally, the bottom of the housing is raised and secured in place.

Abstract: A cotton lint cleaner having a number of new and unique features. The lint cleaner uses a common air stream laden with cotton to be cleaned through a moving screen and then through feed rollers to a cylindrical saw, where a centrifugal air flow doffing impeller doffs the cleaned cotton from said saw, for discharge from the device. Special spring biased feed bars are also a part of this invention. Additional features include special grid bars, special settling and collection chambers, guide vane structure, a rotating paddle wheel vacuum lock, an adjustable vacuum valve control, and filtering and discharging of the exhaust air flow through a cover over the operating drives for the overall machine in order to exclude contamination from the outside air of said drive components. Special tension mountings for the grid bars are also disclosed.

Abstract: An improvement in the production of chopped fibers is provided. Long fibers, commmonly in the form of roving, are fed through a chopper assembly comprising a cutter wheel having a plurality of outwardly-extending blades and a back-up roll having a soft cylindrical surface which the blade edges contact with the fibers therebetween. The chopped fibers then are directed downwardly through a discharge chute to a distribution chute below the chopper where they are directed by air to a point of application, e.g. being mixed with resin and applied to a surface of a mold or mandrel. The chopper fibers have had a tendency to agglomerate into hunks or balls below the chopper assembly and such tendency has heretofore been substantially reduced by the use of static bars located below the chopper assembly. An air system is now provided for directing air downwardly past the chopper assembly to convey the chopper fibers therefrom through the discharge duct and the distribution chute.

Abstract: A continuous in-line flock cutting process is disclosed, for making flock from tow which contains a lubricant which is detrimental to the flock and must be removed.The tow is continuously fed, heat treated and immersed in an aqueous scouring liquid, and is continuously wet-processed. The excess scouring liquid is squeezed out, the tow is rinsed with water, rinse water is squeezed out, and a finish is applied to the tow and partially squeezed out in an in-line continuous process to remove a portion of the applied finish. Thus processed, the still-wet tow is continuously cut into wet flock, the wet flock is then dried and beaten to open up and separate the individual flock particles, and screened.
