20090162464 | Mold for Vulcanizing an Unvulcanized Tire Blank - A mold for vulcanizing an unvulcanized tire blank comprises: two axial members each carrying a molding surface for molding a sidewall of the tire, at least one of the axial members being movable between a position for molding the sidewall and a position for unmolding the tire; at least one molding member for molding a channel in a tread of the tire, the molding member being movable between a channel-molding position and a channel-unmolding position; and axial movement means for axially moving the channel-molding member between its molding and unmolding positions. The axial movement means include releasable connection means between the channel-molding member and the axial member. | 06-25-2009 |
20090218017 | Tire, a Mold for Vulcanizing the Tire, a Method of Fabricating the Mold, and a Mold Matrix - A tire includes a tread in which there is provided a molded channel. The molded channel is interrupted by at least one furrow of the tread and extends along a curved path. The path of the molded channel is preferably substantially parallel to an outside surface of the tread in a radial section plane of the tire. | 09-03-2009 |
20120227879 | HIGH-CONTRAST TIRE PATTERN AND METHOD FOR PRODUCING SAME - Tire having a visible surface comprising patterns contrasting with said surface, said pattern comprising, over the entire surface thereof, a plurality of tufts distributed with a density of at least five tufts per mm | 09-13-2012 |

20140166177 | HIGH CONTRAST TIRE PATTERN - A rubber tire comprising a surface having, over at least a portion of this surface, a pattern comprising a plurality of bars placed substantially parallel with one another, each comprising a tip distant from the surface of the tire and a base materially integral with the tire. Each bar of the plurality of bars comprises two inclined walls extending on either side of the tip towards the base, the angle of inclination of each inclined walls less than or equal in absolute value to 25° relative to a direction perpendicular to the surface. The bases of the bars are not in contact with one another so that the bases of two adjacent bars delimit a residual surface between the bars. The width of the residual surface corresponding to a distance between the bases of the two adjacent bars is less than or equal to half the height of the adjacent bars, the height being between 0.1 mm and 0.8 mm. | 06-19-2014 |
