Abstract: The apparatus is particularly adapted for disintegrating bale-like masses of waste textile strand material that includes synthetic (e.g., polyester, nylon, etc.) textile strands of large-magnitude tensile strength and frequently of considerable length. The length and strength of such strands, in conjunction with their normally quite-random and entangled array within the bale-like masses received by a reclaimer of waste strand material, has heretofore necessitated the manual disintegration of such masses. The apparatus of the present invention automatically and efficiently disintegrates bale-like masses of waste textile strand material of the above-described type, as well as of other types, and does so in a manner which does not so impair desirable physical properties of the strand material as to restrict its various end-uses.

Abstract: A method of, and apparatus for, forming a fiber layer of substantially constant weight per unit length, there being provided supply means for supplying a fiber and air mixture onto a moving, fiber-separating, perforated surface. A suction opening is arranged beneath and extends over a certain zone or region of such perforated surface. The suction opening can be moved forward and backward with respect to the direction of transport of the fiber and air mixture by the perforated surface as a function of a measuring value which is representative of the thickness of the fiber layer deposited upon such perforated surface.

Abstract: A roller cotton gin including a ginning roller and a stationary knife to which seed cotton is conveyed by the friction surface of the ginning roller for separating lint fibers from the cotton seed, and a rotary stripping blade device adjacent the stationary knife having blades forming channel-like pockets therebetween for receiving the seed cotton deposited on the surface of the ginning roller and advanced to the zone of the stationary knife.

Abstract: A method and apparatus are provided for aligning individual fibers parallel to the main fluid stream that is conveying them, using fluid-dynamic forces. This method and apparatus are based on the use of converging streamlines in a nearly irrotational flow to provide the necessary moments to rotate the fibers so that they become parallel to the streamlines. Counterflow jets are provided to create the desired streamline behavior in a main fluid stream. The irrotationality of the flow and the nearly parallel streamlines thus prevent further fiber rotation downstream.

Abstract: A cotton cleaning attachment for a cotton scraper has a separator section mountable at a discharge end of a conventional scraper so as to receive scrap cotton, dirt and debris downwardly under the force of gravity from the discharge end of the scraper and separating the dirt and debris from the cotton. A transfer section, also mountable on the scraper and disposed downstream of the separator section, removes the cleaned cotton from the separator section, and causes the cotton to be fed to a subsequent stage of handling for further processing.

Abstract: A traverse rod for drapes has its pleat hangers attached to elements (e.g. the spaced pivot pins) of a lazy-tong mechanism, whereby the pleats are always evenly spaced regardless of the degree of opening or closing of the drapes. The lazy-tong mechanism (1) can be housed in a rectangular guide box mounted with its longer transverse dimension either vertical or horizontal, or (2) can be attached to hangers carried and guided by a C-shaped channel bar so as to lie behind the drapes carried by the channel bar.

Abstract: In order to remove dust from textile fiber tufts, the tufts are conveyed by an air-penetrable, continuously advancing screening element and a single stream of air is passed a plurality of times through the screening element in order to alternately mix with and become separated from the tufts and the stream is given a net flow in the direction opposite to the direction in which the tufts are being conveyed by the screening element.

Abstract: A device comprises a guide cover extending from above the taker-in roller on one side of the cylinder toward and over a feed roller and defining a passage for the air stream produced by the rotation of the taker-in roller to return fibers entrained in the air stream onto a lap on the dish plate. The guide cover is provided with auxiliary guide plates disposed within the passage and extending respectively from the opposite side walls of the guide cover toward the center of the passage while slanting toward the direction of advance of the air stream with respect to the axis of the taker-in roller when seen in plan, each of the guide plates being provided with a guide face having a progressively reducing width toward its forward end. A control roller is disposed between the guide cover and the cylinder and positioned close to the periphery of the cylinder and the periphery of the taker-in roller.

Abstract: Apparatus for dry-laying cellulosic fibres on a foraminous travelling band comprises a distribution chamber one wall of which facing the band is provided by a vibratable screen. Within the chamber is a rotating brush roll positioned so that the brushes cause the screen to vibrate. Fibres are urged through the screen partly by the action of the brush roll. Provision may be made for recirculating air which has passed through the band back to the chamber.

Abstract: An enclosed axle, inclined wheel caster including a generally disc like pivot support, or body frame member, which may be flat or dished, carrying an axle and a supporting wheel member rotatably mounted on the axle, both of such members being made from stampings, moulding or forgings and a cover formed of opposed saucers, or cupped members, or combinations of these forms, attached to each of the members to give the swivelable caster a generally enclosed form.

The wheels are retained on the axle by means of a locking member engagng the hubs from below and behind a flange on the hubs. By spring action the locking member is pressed against the hubs for braking the wheels and is released by increasing the load on the pivot rod.

Abstract: The magnet carrier assembly of an electrographic copying device is fabricated from a number of separate parts instead of being machined from a single block of metal. The assembly can consist of a tubular body which supports the magnets either on the outside, or inside, peripheral surface. The tubular body can be formed by extrusion integrally with a radial spider connected to a hub which supports the body. In another form the carrier can be built up by combining specially profiled sheet metal strips with other axially extending elements with which they are joined in a tongue-in-groove arrangement.

Abstract: An apparatus for treating a tow of filaments with a fluid, the apparatus forming a tow path therethrough and having a pair of guide surfaces positioned on opposite sides of the tow in series with each other in such a manner that the two path has at least two bends. Fluid nozzles associated with each of the guide surfaces are positioned in such a manner that fluid from these nozzles flows in layers along the guide surfaces and passes through the tow at the bends in the two path. This apparatus is capable of treating a tow under little or no tension, so that it can be used to anneal and shrink tows of certain filaments. The moving fluid advances the tow through the apparatus.
