Abstract

La presente invenzione si riferisce ad un processo e ad un apparato per la produzione di un filato (B) a più filamenti, da polimero polipropilenico. Il processo comporta le fasi di filatura di un filato (A) non stirato, utilizzando una filiera (1) e di avvolgimento del filato (A) non stirato su di una bobina (3), successivamente, il filato non stirato (A) viene svolto in modo tale che non venga impartita alcuna torsione al filato (A), detto filato (A) venendo quindi stirato fra rulli godet (7,9) su di un forno a convezione (11), il filato stirato (B) venendo avvolto su di una bobina (15). (Figura 2)
