MOULD PROVIDED WITH BLADES FOR PLACING A REINFORCEMENT IN A TREAD OF A TYRE

摘要

The invention relates to a mould for manufacturing a tyre, said mould comprising a moulding ring, said ring comprising a plurality of sectors, each sector comprising a plurality of interchangeable elements (18), said elements supporting a moulding surface (20) from which at least two raised elements rise on the left and right (22G, 22D) separated by a transverse distance (D22), the mould comprising a blade (24) for transversely placing a reinforcement (10) in the transverse direction (DT) between the two raised elements (22G, 22D) and offering two intermediate bearing points (PIG, PID) separated by a recessed portion, said intermediate bearing points (PIG, PID) being located at a height (HIG, HID) no higher than the height (H22G, H22D) of the raised elements (22G, 22D), the bearing distance (DA) separating said two intermediate bearing points (PIG, PID) being smaller than the transverse distance (D22) separating the two raised elements (22G, 22D), and the recessed portion of the blade not offering any bearing points.
