Abstract: A tire rasp blade for a buffing machine including least three arc segments of buffing leading edges with coarse and fine pitches with variable segment angles are arranged in between the terminal ends, to form arcuate working end with a working end angle. The first arc segment is defined by a coarse pitch and is arranged at one terminal end followed by an arrangement of second and third arc segments that are defined by an incremental fine pitch.

Abstract: Article and method of making an abrading wheel having a sintered metal core and radially inward openings having curved inner edges to reduce stress in operation and to improve the ability of the wheel to clear residue from the wheel during operation.

Abstract: A method and apparatus for finishing the surface of rubber or synthetic covered rollers (10) is disclosed. As seen in FIG. 3, a rotating hub (16) having a circumferential abrasion band (47) and an adjacent set of rasp blades (20) arranged end-to-end and extending circumferentially about the hub is used to progressively and sequentially removebands of surface material by cutting and then abrading as the hub and roller are rotated and one is moved axially relative to the other.

Abstract: A rasp hub for use in tire retreading machines includes two side plates with mounting pins extending between the plates. Rasp blades arranged in stacks are mounted on the mounting pins. The stacks extend end-to-end circumferentially about the hub. The center portion of the mounting pins is curved so that the cut profile of the blades is convex. The blades are inclined relative to a plane perpendicular to the axis of rotation to define a cut angle. The center planes of the mounting pins intersect, preferably close to the axis of rotation of the hub, to reduce deviation of the blades from the concentricity.

Abstract: A rasp blade includes a mounting aperture having at least two aperture segments which are laterally spaced and communicate with each other. Each aperture segment may independently secure the blade on a mounting pin. Alternate blades are mounted using different aperture segments to fix adjacent blades in laterally offset positions, thereby staggering the teeth in adjacent blades.

Abstract: The present invention is directed to a rotatable abrading wheel assembly useful to finish rubber articles such as tire casings. The assembly has three rotatable wheels, with a central abrading wheel disposed between a pair of lateral support wheels. Each of the three wheels is stamped and formed from sheet metal stock and includes one or more apertures to accommodate an abrading tool drive shaft. The central abrading wheel has a diameter greater than that of the lateral support wheels to thereby provide peripheral abrading portion which is comprised of a series of circumferentially spaced teeth.

Abstract: A rasp hub assembly for use in a tire buffing machine is disclosed. The hub assembly includes two end plates, and a set of tire rasp blades and spacers arranged in alternating circumferential rows. The blades and spacers have conforming nonplanar elongated bodies, with the blades nested with adjacent spacers. The resulting rasp hub assembly allows the use of an even or odd number of rasp blades in each row, and provides various benefits further described in the specification.

Abstract: An improved abrading device made with predetermined cavities. In this device, metal grit is magnetically positioned and then brazed on a metal surface to form a generally uniform distribution of the metal grit on the land area and not on the cavities of the metal surface.

Abstract: An abrading apparatus formed from sheet stock and processes for making the same are disclosed. The abrading apparatus has a base with a plurality of cantilevered members extending from the periphery of the base with each cantilevered member formed to provide a discontinuous abrading surface along the periphery of the apparatus. A process for making this abrading apparatus includes the steps of forming from a single piece of sheet stock a base having a plurality of cantilevered members, positioning the cantilevered members at an angle relative to the plane of the base, and forming the cantilevered members to provide exterior surfaces upon which an abrasive surface may be provided.

Abstract: A tire trimmer tool has an elongated handle and a U-shaped frame to which a blade of undulated sheet metal is detachably mounted. The undulations comprise closely-spaced parallel ridges which extend front and rear, are open on their underside and are united by narrow connecting webs. The undulations are arranged across the full width of the blade; and the outermost undulations which comprise the two sides of the blade have upturned walls, the edge of which seat is facing slots provided the legs of the U-frame; and an adjustable clamp which connects the two legs secures the blade in place. The fore end of the blade is sharpened on its underside and a narrow transverse portion of the blade therebehind is struck or turned upwardly across the full width of the blade and limits bowing of the blade in response to tightening of the clamp.
