MODIFIABLE ELEMENT FOR SHAPING A RAW TYRE BLANK

摘要

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.
