The mould (1) consists of two hinged halves (1a, 1b) that move relative to one another as they open and close, and a lock (14) that extends the whole length of the opening edges. The lock consists of two hooks (17a, 17b) with facing recesses (18a, 18b) for a rotating wedging strip (19). The strip pivots adjacent to one hook and engages with the opposite one to lock the two mould halves in the closed position, and retracts into one of the recesses to allow the two halves to separate. The strip is engaged, for example, by a roller mechanism on a mould carousel, and retracted by a return spring. |
