Abstract: A method of forming a tread comprising two or more layers of rubber is described. The method includes the steps of: extruding a rubber compound through an extruder and a gear pump and mixing with an accelerant and then applying a continuous strip of rubber directly onto a tire building machine to form a first layer of rubber having a first cure rate; adjusting the amount of accelerant to obtain a second cure rate different than said first cure rate, and then applying a strip of rubber having a second cure rate onto the tire building machine, wherein one of the cure rates is faster than the other cure rate.

Abstract: A system for manufacturing an elastomeric tire utilizing a separate formation of a package having a tire core shape and containing tire belts, plies and beads. The package is formed by a laying up of layers of pre-cure elastomer intradigitated with sections of porous fabric, where the fabric fibers are placed at desired crossing angles to one another, and the pre-cure elastomer layers are positioned therebetween as a sandwich, with the sandwich then cold rolled into the tire core shape. Inelastic hoop shaped beads are fitted to and encapsulated in the tire core side walls ends and, as required, an inelastic belt is fitted around the tire core tread area that is secured thereto as by cold rolling a layer of pre-cure elastomer thereover, completing the tire core package. The tire core package is fitted into a mold, preferably a spin casting mold, and is supported therein equidistant from the mold cavity walls to receive an elastomer sprayed therein as the mold is spun. During spinning, the exothermic heat of reaction of the sprayed elastomer constituents as is generated as they are mixed and sprayed into the mold, completes the cure of the pre-cure elastomer, providing a homogenous finished tire with the belts, plies and beads optimally positioned therein.

Abstract: This invention relates to a retreadable tire which contains a non-black colored rubber carcass cushion layer sandwiched between its tire tread and tire casing. The non-black colored rubber carcass cushion layer acts both as an adhesive and transition layer for adhering a cured or uncured tire tread to the cured tire carcass. Such carcass cushion layer also acts as a detectable color indictor for indexing and monitoring a complete removal (e.g. by buffing, abrading, or cutting) of the circumferential rubber tire tread and partial removal of the carcass cushion layer without removing the entire carcass cushion layer. The invention also relates to a method of retreading a cured rubber tire carcass by completely removing a circumferential, carbon black reinforced (and therefor a black colored) tire rubber tread together with a partial removal of the contrastingly colored cured rubber carcass cushion layer to a depth indexed and/or determined by an automated rubber cushion layer color sensing means, or apparatus, followed by applying a non-black colored uncured circumferential rubber carcass cushion layer and carbon black reinforced (therefore black colored) tire tread thereon to form an assembly thereof and vulcanizing the assembly in a suitable mold to form a retread tire.

Abstract: A binding rubber extruder for retreading tires is provided with an extruder head, an axis of which extends essentially vertically to a surface of a carcass. The revolving speed of the rotatably drivable carcass and the extrusion speed are adjusted relative to one another. The extruder head is provided with a nozzle, that has a radius of curvature that corresponds at least to a greatest radius of the carcass whereby the nozzle is pressable against the carcass surface with a gentle, elastic force.

Abstract: A tire is made by first fitting a pair of bead rings interconnected by reinforcement over a gas-pervious annular liner to form an annular core assembly and then inflating the core assembly by directly contacting same with a fluid to impart to the core assembly an inwardly open U-shaped section. This U-section core assembly is then spacedly enclosed in a mold which is filled around the U-section core assembly with a hardenable elastomer which is hardened so it bonds to the reinforcement, rings, and liner to form a tire. Finally the liner is deflated and the tire is demolded. The liner has a pair of opposite end edges and is inflated by sequentially clamping each of the edges against a support so as to define between the liner and the support a pressurizable chamber, displacing one of the clamped edges toward the other so as to outwardly bow the liner, and introducing a fluid, typically air, into the chamber. It is also possible to mount the rings in the mold and thereafter introduce the liner into the form for fitting it and the rings together.
