Abstract
A method for manufacturing a studded tyre includes producing an unvulcanized tyre, inserting studs for the tyre into seats in a curing mould, disposing the unvulcanized tyre in the mould, closing the mould, curing the tyre, and opening the mould to extract the cured tyre. The cured tyre includes a tread band including a plurality of metal studs partially projecting from a radially outer surface of the tread band. Inserting the studs for the tyre into the seats includes disposing a stud-holding device supporting a plurality of the studs inside the mould, and expelling the studs from the stud-holding device so as to dispose the studs in the seats. A stud-holding device includes a toroidal body including a plurality of through holes and an expulsion mechanism. The through holes are capable of accepting studs and the expulsion mechanism is capable of expelling the studs in a substantially radially outward direction.
