20110108179 | Tire with Crown Comprising a Layer of Very High Modulus Rubber Mix - A tire comprising two beads ( | 05-12-2011 |
20120080128 | TIRE WITH TREAD PROFILE HAVING CONTINUOUS CURVATURE AND METHOD FOR FORMING TIRE - A tire and a method for forming a tire tread are disclosed. The tire includes a tread defining an inferior tread profile and a superior tread profile, the superior tread profile having a generally continuous curvature between an edge of contact and a top center point. The superior tread profile includes a plurality of control points and a plurality of splines. Each of the plurality of splines extends between at least two of the plurality of control points. Curvatures of adjacent splines are generally equal at each of the plurality of control points. | 04-05-2012 |
20120192637 | Method for Determining the Transverse Curve of a Generally Cylindrical Receiving Surface - Method for determining the transverse curve of a receiving surface of generally cylindrical form designed, during the assembly of the tire blank, to receive the components forming a crown belt in which threads are placed at zero degrees relative to the longitudinal direction, the threads being continuously wound without tension. The elongation rate (A) to be applied to a turn of a zero-degree thread is determined according to the desired pre-tension (A=f(T)), according to its axial position in the tire. Depending upon the radial position (Rf) of the thread of the said turn in the tire fitted into its mould, the initial radial position (Ri=Rf/(1+A)) is determined so that the thread of the turn in question sustains the desired elongation rate during forming in the press. The transverse profile (Rfdp) of the receiving surface is determined, in the axial location of the said turn, by subtracting from the initial position of the thread (Ri) the thickness (e) of the components placed radially inside the turn of the said zero-degree thread (Rfdp=Rf/(1+f(T)) e). | 08-02-2012 |
