Publication number: 20120192637Abstract: 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.Type: ApplicationFiled: June 14, 2010Publication date: August 2, 2012Inventors: Philippe Tramond, Jean-Yves Denoueix, Bernard Guerinon
