Abstract: In accordance with the invention, the breaking and stretching machines have pressure heads, each one being essentially constituted by two opposed complexes, upper and lower, each one of which includes at least two transmission chains of the Renold type which are meshed with two chain pinions (double, triple, etc) fitted on two strong parallel shafts that are supported by appropriate bearings attached to the lateral elements of the machine bedplate; those corresponding to the lower complex are fixed, while those corresponding to the upper complex are moveable, so that the latter complex may adopt, with respect to the other complex, two limiting positions; one of separation, which permits the introduction of the layer of fibres, and the other, where the elements approach one another, to be utilized during the work and in which the pressure can be adjusted.

Abstract: An improved method and apparatus for plucking fiber tufts from a fiber bale held by a supporting frame which is reciprocally displaced along a carrying passage over a plucking roller. A pair of conveyer means are disposed with an intervened space therebetween and the plucking roller is disposed in the abovementioned intervened space. An auxiliary conveyer means is disposed at a position adjacently outside one of the conveyer means. These three conveyer means are arranged in an alignment. The supporting frame is capable of being reciprocally displaced by the conveyer means between displacing terminals on said conveyer means and is capable of being displaced to a waiting position on one of the conveyer means which is outside of the displacing terminal on that conveyer means and at a side of the auxiliary conveyer means.

Abstract: An improved process and equipment for seed defiberization, for example cottonseed delinting, wherein the seed is defiberized by contact with particular abrasive surfaces. In one preferred embodiment, a conventional cotton-seed delinter is equipped with an abrasive faced cylinder instead of the conventional shaft mounted ginning saws. The abrasive cylinder comprises a shaft mounted cylinder of approximate gin saw diameter which cylinder has bonded or adhered to its facial surface an open pattern of about 40 to about 80 abrasive grit particles per square inch. The abrasive grit particles, preferably tungsten carbide grit, are sized to U.S. Sieve Series numbers of about 12 to about 40. Replacement of the ginning saws with the abrasive face cylinder requires modification to the delinter gratefall rake and seed seals to adapt their shape and clearance to the comparatively flat abrasive cylinder face.

Abstract: This invention relates to a staple draft device comprising a pair of feed rollers and a pair of drawing-off rollers, said pairs determining therebetween the course of a staple lap to be drawn off, there being at one side of said course a feed roller with needle-like projections and a control roller also with such projections, and at the other side of said course a supplementary needled-surface roller which co-operates solely with said needled-surface feed roller, and a single levelling-down roller which is smooth, co-operates solely with said needled-surface control roller, and is preferably positively driven at an angular speed such that the peripheral speeds of said levelling-down and control rollers with needle-like projections are equal.

Abstract: Apparatus and method for forming a fibrous batt of controlled thickness and uniformity with fibers flowing from the discs of an attrition mill. The fibers are directed from the outlet of the mill in an air stream in a path of decreasing radius of curvature so that the fibers accelerate toward a collecting screen until they reach a forming chamber communicating the path with the screen. The acceleration of the fibers in the path prevents fiber contact and minimizes fiber contact with walls of the equipment thereby avoiding fiber agglomeration.

Abstract: Nonwoven fabric is fed at a first rate into the bite between a first shredding element and a stationary working surface. The first shredding element has a plurality of projections which penetrate the fabric and at least substantially shred the fabric as the first shredding element is moved past the working surface at a second rate substantially greater than said first rate. The at least substantially shredded fabric then passes between the first shredding element and a second shredding element, the latter being driven at a third rate substantially different from said second rate to effect additional shredding and to separate the resulting staple fibers. A forced draft fan pulls air past the fabric as the fabric is being worked, to maintain the fabric temperature below the fusion temperature of the fibers.

Abstract: Fibrous web structures in which the individual fibers are uniformly felted in random orientation are produced by projecting a stream of solids suspended in air toward a moving porous collection surface. The fibers are maintained in a controlled condition uniformly dispersed in air during transit from the nozzle to the porous collecting surface and before the stream of air has spread to the point of disrupting the uniform fiber dispersion, the fibers are felted and collected on the porous support while air is continuously passed through the support to insure no gravity free fall of fibers. Liquid or dry adhesive binders may be incorporated into the structure at any convenient stage of the process but preferably before the web structure is formed on the moving support.

Abstract: A tracking device is illustrated wherein a rotatable guide is moved in a path approximating the path of the trumpet or other coiler sliver guide means responsive to suitable gearing and wherein the rotatable guide has a scalloped surface over which the sliver is fed for minimizing contact between the sliver and the rotatable guide and producing positive rotation of the rotatable guide by the sliver, avoiding sliding friction therebetween.

Abstract: A carding method in which the rotary flats of a carding machine are driven intermittently so that each time the flats are driven only a portion (1/6 to 1/4) of the flats opposed to the cylinder of the machine are replaced by fresh flats, thereby decreasing the amount of good fibers in the waste, particularly when carding synthetic fibers.The carding machine is provided with a solenoid clutch in the drive mechanism for the rotary flats and the flat cleaning means, and with a timer for controlling the clutch so that the flats can be intermittently driven at desired drive and stop intervals. For carding polyester fiber, the drive interval may be enough to replace one-fifth of the flats opposed to the cylinder of the machine with fresh flats, and the stop interval may be as much as sixty minutes.

Abstract: Flat clothing is illustrated utilizing metallic wire segments affixed to an elongated base strip, within a channel therein extending the length of the strip, by an adhesive which is carried within vertical passageways or reservoirs extending entirely across vertical side surfaces of the shoulders of said segments affixing the segments to each other and to the base strip.

Abstract: A rotating receiving plate is provided having a vertical axis, onto which the coiled yarn package is formed. Said receiving plate is urged upwardly against a rotating depositing disc, the axis of rotation of which is eccentric with respect to the axis of rotation of the receiving plate. The depositing disc is carried by a rotating hollow shaft presenting an upper open end and a radial bore in correspondence of its bottom end integral with the depositing disc. Integral in rotation with the depositing disc there is provided a thread guide. To the supporting frame there is secured a fixed member presenting an outer annular friction surface. The yarn is withdrawn from a suitable supply, passes through the hollow shaft, out of the radial bore, it is further laid onto at least a portion of the annular track and it is hence positively fed, through a bore provided in the depositing disc, onto the receiving plate, in loops progressing along an annular path, to form a coiled yarn package.

Abstract: Process and apparatus are disclosed which are suitable for high speed production of uniform, lightweight webs by air-laydown of textile fibers. A toothed disperser roll doffs the fibers into an air stream of high uniform velocity and low turbulence to form a thin fiber stream from which the fibers are deposited in web form on a moving screen. A curved disperser plate, shrouds the disperser roll and prevents premature doffing. By using a disperser plate with a rough surface, preferably one having lateral grooves, web uniformity is remarkably improved.

Abstract: An apparatus and method wherein a tow of continuous filaments is fed to a tow cutter and severed into fibrous material of predetermined staple length while the fibrous material delivered from the tow cutter is fed to and through at least one textile picker. The fibrous material may be formed into laps at the picker for being subsequently processed through cards, or the fibrous material may be fed in loose fibrous form from the picker to a bank of cards. Means are provided for automatically controlling operation of the tow cutter and pickers and for controlling feeding of the fibrous material to the pickers.
