Abstract

Patente de Invenção:<B>"MéTODO E ARRANJO PARA IGUALAR INTEIRAMENTE A TENSãO DAS FIBRAS óTICAS"<D>. A invenção refere-se a um método para igualar inteiramente a tensão de fibras óticas, no qual as fibras óticas (3) são passadas a partir de carretéis de partida (1) através deuma estrutura de roda equalizadora (4) para o próximo estágio do processo. De modo a obter uma solução flexível e simples, a estrutura de roda equalizadora (4) é formada de duas rodas (5, 6) em seq³ência quando visualizadas a partir da direção do movimento das fibras (3), de cujas rodas, a primeira roda (5) é adapatada para fornecer mais fibras para o espaço entre as rodas (5, 6) do que o que passa sobre a segunda roda (6).
