<p>Equipment for moulding components each having a core formed by two layers of thermoplastic material joined together along a join line comprises first and second half-dies (4, 8) having a sharp cutting portion (24) and a substantially flat abutment surface (26), respectively. The equipment also comprises spacer means (36) for limiting the relative movement of the two half-dies (4, 8) towards one another so that there is a predetermined clearance (38) between the sharp cutting portion (24) and the abutment surface (26) when the half-dies are in the closure position. <IMAGE></p> |
