Abstract

Patente de Invenção: <B>"PROCESSO PARA PRODUçãO DE UM CABO óPTICO, COM COMPRIMENTO EXCESSIVO DOS GUIAS DE ONDAS"<D>. Em um processo para produção de um cabo óptico (1) ou de um elemento modular para um cabo óptico, no qual uma fita metálica descarregada de uma bobina de reserva é moldada gradualmente para um tubo fendido, pelo menos um guia de ondas (2), descarregado de uma outra bobina de reserva, é introduzido no tubo fendido, ainda aberto, a fenda longitudinal do tubo fendido é fechada por solda e, depois da solda, é produzido no tubo metálico um comprimento excessivo dos guias de ondas em relação ao tubo metálico, o tubo metálico (3) soldado é enrugado, entalhado ou ondulado (3b), para produzir o comprimento excessivo.
