Abstract: Systems and methods for downsizing tires, and an automated downsizing apparatus utilize a cradle, mandrel table, cutting apparatus, and a control unit. In various embodiments, a tire mounted on the cradle may be received by the movable and rotatable mandrel table, and positioned for engagement with the cutting apparatus. Users may customize one or more cutting configurations to be executed by the control unit. The control unit positions the mandrel table and cutting apparatus to remove portions from the tire, according to the cutting configurations. During tire downsizing operations, one or more system parameters may be monitored to determine compliance with the selected configuration, and the automated execution may be manually overridden.

Abstract: Method for bonding by wrapping a medium which expands transversely to a winding with an adhesive tape, in which: an adhesive tape is unrolled from an adhesive tape roll, the unrolled adhesive tape is provided on one side of a carrier film (1) with an adhesive cement layer (2) and on an opposite side partially with a separating agent layer (3), wherein the area covered by the separating agent layer (3) takes up not more than 50% of the total area of the carrier reverse side, wherein at least the surface of the side of the carrier film (1) which is furnished with a separating agent layer (3) is etched, the adhesive tape is wound around the medium which expands transversely to a winding, so that at least a portion of the adhesive tape is bonded to a lower winding ply by the adhesive cement layer (2).

Abstract: Device for mechanically splitting finite textile fiber bundles, comprising n individual fibers (n?2) in fiber bundles having less than n individual fibers and/or individual fibers, characterized in that in a milling chamber that is closed off from the outside and that has one or more dead spaces of at least 10% of the milling chamber volume and in which one or more rotating striking elements operate in a non-cutting manner and so as to reduce load peaks and at a rotational speed that can be adapted to the material but that is at least 200 r.p.m., the material is adjustably input in different amounts in batches, treated for an adjustable duration, and then discharged again from the milling chamber.

Abstract: The rag tearing machine embodies an inlet station 1 in which the materials to be processed for a first time 23 and recycled waste 19 are poured, separately, onto the circulating belt 2. Several rag tearing stations (4a, 4b) are each followed by fan groups (5a, 5b), including side doors 8 access for which throw a material coming from the preceding station to a filtering box 9 in which powder, after a sharp bend 10 separates from the material by passing through a pierced plate 11; the material then falls down and passes to the following station and so on until the end of the machine. The machine further includes gates 14 for bypassing subsequent stations and if the material is considered sufficiently processed, the respective gate is opened and the material goes out of the machine through a duct 15.

Abstract: Apparatus is provided for separating cellulose fluff fibers from waste fibrous material resulting from the manufacture of absorbent products from cellulose fluff fibers, comprising:an apertured cylindrical separator disposed in a housing and having a central passage in flow connection with the inlet;the cylindrical separator having apertures therethrough large enough to permit cellulose fluff fibers to pass therethrough but small enough to screen out larger non-fluff material from the waste fibrous material;means in connection with the first outlet for controlling flow therethrough of air and entrained waste fibrous material, for providing a balance between flow rate and differential pressure across the apertured separator sufficient to prevent blockage of the apertrues in the separator by waste fibrous material too large to pass through while permitting cellulose fluff fibers to pass through.

Abstract: The invention relates to bleached cotton fibers and to absorbing materials for disposable articles. Its object is a process for shortening bleached cotton fibers consisting in(a) moving a fiber pad (1) between a trough-plate (2) and a feed roller (5) exerting a pressure between 0.3 and 0.6 MPa on the fiber pad,(b) pulling the fiber pad (1) beyond the trough-plate (2) bevelled at (9) so as to cut the long fibers constituting the fiber pad,(c) reconstituting the sheet.This process makes it possible to obtain fibers which can be used directly in diaper-making machines. The disposable articles so produced offer remarkable absorbing properties.

Abstract: The invention relates to a method and apparatus for separating a nonwoven fleece-like filling or stuffing material from a fabric covering material in which no manual work is required. Three operations are provided. In the first operation the material is cut up, in the second broken down by tearing or fulling work and in the third operation separated by centrifuging. The apparatus consists of a punch (11), draw-in rollers (14, 15) and a carding machine (12) from which the material is transferred via brush rollers (20) to centrifuging rollers (13) for separating the nonwoven material from the covering material.

Abstract: An improved waste shredding machine and method wherein insufficiently shredded waste is returned to the shredding machine.

Abstract: A process for feeding defibrators with sheet pulp delivered in batches. Rectangular sheets are deposited one behind another on a feed belt with their longitudinal axis offset by 45.degree. with respect to the direction of advance of the belt, whereupon two equal lateral parts from each sheet are folded back along two folding lines parallel to the direction of advance of the belt, the distance e between said lines being equal to l/.sqroot.2 and two consecutive sheets being mutually apart by x=L/.sqroot.2, L and l, respectively, being the length and the width of the pulp sheet. Feeding a machine for diapers.

Abstract: Cord or fabric is reduced to short fiber lengths by applying a point contact compressive force thereto.

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 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.
