Abstract

"MéTODO E APARELHO PARA A PRODUçãO DE UM ARTIGO DE MATERIAL ELASTOMéRICO". O método e aparelho são para a produção de um artigo de material elastomérico que tenha simetria circular e que seja aberto em ambas as extremidades, particularmente para a produção de foles protetivos para veículos. O aparelho compreende um molde (10) compreendendo uma porção externa (12, 14) e uma porção interna (16) entre as quais são definidas uma cavidade moldante (24) e uma região de injeção (28). O artigo (74) de material elastomérico que é formado na cavidade moldante (24) permanece ancorado à porção (16) do molde depois que a porção externa (12, 14) do molde tiver sido aberta. Antes do artigo (74) ser removido automaticamente da porção interna (16) do molde, uma tampa supérflua (76) formada pelo material que se solidifica na região de injeção (28) é removida por meio de um membro (60).
