TYRE COMPONENT PART PRODUCTION METHOD AND MACHINE

摘要

A method and machine (A) for producing a tyre component part by gradually depositing a strip (7) of elastomeric material on a toroidal surface (4) of a support (1) rotating about its axis (3); the machine incorporating an applicator roller (9) and a pressure roller (13) for respectively applying and pressing the strip (7) on the surface (4), and which are moved simultaneously crosswise to a deposition path (P) of the strip (7), so that a contact point (15) between the applicator roller (9) and the surface (4) moves in a radial plane (Pi) of the support (1), and a contact point (15) between the pressure roller (13) and the surface (4) moves on a surface (S) generally parallel to the radial plane (Pi); the pressure roller (13) being mounted to oscillate about an axis (19), which is moved simultaneously with the two rollers (9, 13) so as to translate parallel to the radial plane (Pi).
