Abstract

Patente de Invenção: <B>"PROCESSO PARA O PROCESSAMENTO SEPARADOR E/OU REMOVEDOR DE FOLHAS DE PLáSTICO PRé-ACABADAS"<D>. A invenção refere-se a um processo para a preparação de folhas de plástico com um contorno predeterminado e/ou uma distribuição de espessuras uniforme ou não-uniforme, por processamento separador e/ou removedor de folhas de plástico pré-acabadas, especialmente para a preparação de velas flexíveis para válvulas do coração artificial. A fim de que se possa conseguir distribuições de espessuras localmente diferentes de uma folha, bem como de um canto de fechamento liso da peça de folha cortada, segere-se que a folha de plástico seja separada e/ou removida superficialmente até a extensão de espessura desejada respectiva, por meio de um feixe de raios laser, ao longo do contorno predeterminado.
