Title (EN) MODIFIABLE ELEMENT FOR SHAPING A RAW TYRE BLANK
(FR) ELEMENT MODIFIABLE DE MISE EN FORME D'UNE EBAUCHE CRUE DE PNEUMATIQUE
Abstract:
(EN) The invention relates to an element (12) for shaping the circumferential portion of a raw tyre blank that is substantially rotationally symmetrical about a main axis (X), including a radial bearing surface (16) for bearing on a circumferential portion of a radially inner surface of the blank. The element (12) is arranged so that the radial profile of the bearing surface (16) is modifiable.
(FR) L'élément (12) pour la mise en forme d'une portion circonférentielle d'une ébauche crue de pneumatique sensiblement de révolution autour d'un axe principal (X) comprend une surface (16) d'appui radial sur une portion circonférentielle d'une surface radialement interne de l'ébauche. L'élément (12) est agencé de sorte que le profil radial de la surface (16) d'appui est modifiable.
