Abstract:
A rasp blade includes a mounting aperture (30) 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:
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 method and apparatus for finishing the surface of rubber or synthetic covered rollers (10) is disclosed. As seen in Figure 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:
The present invention is directed to a rotatable abrading wheel assembly (20) useful to finish rubber articles such as tire casings. The assembly (20) has three rotatable wheels (22,24), with a central abrading wheel (22) disposed between a pair of lateral support wheels (24).Each of the three wheels (22,24) is stamped and formed from sheet metal stock and includes one or more apertures (26) to accommodate an abrading tool drive shaft. The central abrading wheel (22) has a diameter greater than that of the lateral support wheels (24) to thereby provide peripheral abrading portion which is comprised of a series of circumferentially spaced teeth (30).

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 a re 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 cente r planes of the mounting pins intersect, preferably close to the axis of rotation of the hub, to reduce deviation of the blades from the concentricit y.
