Abstract: A method of laminating a vulcanized tire includes providing a vulcanized tire having a circumferential tread and a pair of sidewalls constructed of a base rubber. The method further includes cleaning the circumferential tread, providing a laminate, and forming a plurality of holes in the laminate. The method also includes applying the laminate to at least a portion of one of the circumferential tread and a sidewall of the vulcanized tire. The method further includes applying pressure to the laminate, thereby evacuating air between the laminate and the circumferential tread of the vulcanized tire and curing the laminate.

Abstract: This device, designed for cutting the grooves of pneumatic tire treads, includes a re-grooving tool having two distal cutting points that creates grooves in the tire treads having two subgrooves. The grooves improve the fuel efficiency of vehicle and the subgrooves improve channeling and clearance of rain, snow, mud, and other hazardous materials on the road.

Abstract: A method of forming a tire includes a mold having a molding cavity defined at least in part by an outermost molding surface and a pair of opposing shoulder-forming portions. The mold includes a sipe-forming element spaced apart inwardly from the pair of opposing shoulder-forming portions with a knife edge oriented towards a first shoulder-forming portion and a knife edge translation member arranged outside the mold cavity and configured to translate in a direction towards the first shoulder-forming portion and from which a sipe-forming portion extends. The method further includes arranging an uncured tire tread within the mold, molding the uncured tire tread, and demolding the tire tread such that the sipe-forming element forms a sipe by the knife edge lacerating a thickness of the cured molded tread as the sipe-forming element is pulled in a direction toward the shoulder-forming portion.

Abstract: A pneumatic tire capable of discharging static electricity from a vehicle to a road surface wherein the pneumatic tire includes a base portion, a cap portion and a conductive portion, wherein the base portion is formed by spirally winding a ribbon-like rubber strip continuously from one tread edge side to the other tread edge side, without interrupting, with a gap portion formed by separating the side edges of adjacent ribbon-like rubber strips, and wherein the gap portion is formed such that the ribbon-like rubber strip is locally bent.

Abstract: Molding element for molding and vulcanizing a tire tread, having a tread surface contacting the ground when rolling, having a molding surface to mold part of the tread surface and a blade of length and of height H to mold a sipe or a groove in the tread, having a rounded end extending along its length in a direction of extension X. The molding element has two cutting means to cut a cover layer applied to a green form of the tire, positioned on either side of the blade at a certain distance from this blade, each cutting means having a cutting edge extending in the direction of extension, making an acute angle α in a sectional drawing perpendicular to direction of extension X able to cut the cover layer, the distance between this cutting edge and the molding surface being lower than the height H of the blade.

Abstract: 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.
