For eliminating burrs which form on moulded, or injected products, a moulding device and, in particular, a tire-vulcanizing mould, is provided with a plastically and elastically deformable portion on the coupling surface between the corresponding elements. The coupling, between the facing surfaces, is not simultaneous, but involves a portion of surface having an amplitude that increases in its size, during the shutting movement of the mould. |
