Abstract

<B>"PROCESSO PARA PRODUçãO DE ARTIGOS COM BORDAS CORTADAS AO COMPRIDO LIVRES DE ESFORçOS"<D> A presente invenção se refere a um processo para produção de artigos com bordas livres de esforços, que compreende o fendimento de uma folha de cobre ou liga, de cobre, para proporcionar tiras do material de cobre, aquecimento das tiras em um forno a uma temperatura de 200-250 C, sob uma atmosfera protetora e resfriamento das tiras à temperatura ambiente, as tiras assim produzidas sendo de utilidade na fabricação de artigos produzidos por estampagem.
