<p>A tread band (7) of raw elastomeric material is circumferentially applied around a bearing structure (3) incorporating reinforcing cords, for forming a green tyre (2) subsequently submitted to a curing treatment. The tread band (7) is formed by: making an underlayer (18) of raw elastomeric material; making blocks (12) of raw elastomeric material; applying the blocks (12) mutually spaced apart according to a predetermined tread pattern, onto the underlayer (18). During introduction of the tyre (2) into a curing mould, the blocks (12) are put in alignment with respective forming recesses (39) before closing the mould (38), so that each block (12) is engaged in the respective forming recess (39), following closure of the mould (38).</p> |
