Present invention refers to a mini-blade (1) which body (2) has an inner edge (4) in which there is, at least, one transversal tab (6) that constitutes a retention means of the mini-blade (1) in an adapter device (20); between the inner (4) and the external (3) edges, the body (2) has the sufficient extension to form clamping portions (7)(8) that allow the application of clamping peripheral tabs (30). The invention also refers to an adapter device (20) that, for the mounting of a rotary work structure (40) of pneumatic roughing down, includes clamping sets (20) composed of ending supports (21)(22) and intermediary separator supports (23), all of which have clamping transversal peripheral tabs (30) that form jaws capable of clamping the clamping positions (7)(8) of the mini-blade (1). The different supports (21)(22)(23) that form the clamping sets (20) are arranged attached one to another, in train, with the mini-blades (1) interspersed in their jaws, in such a way that the toothed external edge (3) of these last ones protrudes from the clamping set (20).

A grinding assembly (10) contacts a tire (T) supported by a frame (F) relative to the tire. The grinding assembly includes at least one section, and an axial positioning assembly supporting the at least one section (10A,10B). The axial positioning assembly enables the at least one section to be axially repositioned relative to the tire. The at least one section includes a grinding head (24), where the grinding head includes a grindstone rotatably supported thereon, the grindstone having rounded shoulders at its axial extremities. The grinding assembly further includes a radial positioning assembly (18) supporting the grinding head for radial movement with respect to the tire.

Particular embodiments of the invention comprise multi-wear layer tire treads for retreaded tires and methods of forming retreaded tires. In particular embodiments, a multi-wear layer tire tread includes a thickness bounded depth wise by a ground-engaging top side and a bottom side, the thickness extending laterally between opposing side edges and longitudinally in a lengthwise direction of the tread. Such tire tread may further include a removable tread portion recessed from the top side to form a subsequent wear layer, the removable tread portion extending into the tread thickness from the bottom side and terminating a distance below the top side, the removable portion having a width arranged between opposing interior surfaces of the tread recessed below the top side.
摘要:
A system and method for removing an outer layer of resilient material from an object to achieve a target outer dimension includes performing an initial cut at a cutting depth to remove an outer layer of the material. A parameter indicative of a work input to a cutter that performed the cut is acquired and used to determine the cutting depth that will be used for performing a subsequent cut to remove an additional layer. In this way, subsequent cuts are performed until the target outer dimension is achieved.
摘要:
A retreaded tire having improved balance is produced with high efficiency. The thickness of a joint part (F) in a retreaded tread rubber (T) is the largest value on the circumference. In the application of a retreaded tread rubber (T), when the position of the joint part (F) is rendered consistent with the minimum position (S) where the rubber gauge (G) as measured in a tire radial direction from a retreaded face (K) in a base tire (D) to the outer face of the outermost belt cord (L) embedded in the outermost belt layer, among the belt layers constituting the belt, located on the radial outermost side of the tire is minimal on the circumference(corresponding to the light point position of static unbalance), the total rubber gauge of the tread rubber (T) at the joint part (F) surely approaches to the total rubber gauge at other circumferential position, whereby poor balance can be effectively reduced.

A grinder assembly (10) contacts a tire (T) supported by a frame (F) relative to the tire (T). The grinder assembly (10) includes at least one section, and a vertical repositioning system (118) supporting the at least one section. The vertical repositioning system (118) enables the at least one section to be vertically repositioned relative to the tire (T). The at least one section includes a grinding head (24), a radial positioning system (18) supporting the grinding head (24) for radial movement with respect to the tire (T), and a tilt adjuster (90) provided adjacent the grinding head (24) to provide for pivotal movement thereof. The vertical repositioning system (118) includes at least one rail extending along the frame (F), and a rail carriage supporting the at least one section on the at least one rail, the rail carriage being vertically repositionable along the at least one rail.
