Abstract

Un método para aplicar traccion a un elemento cilíndrico elongado (5) producido por la fusion de una porcion final (2A) de una preforma (2) de material de vidrio, donde un dispositivo de traccion (3) puede conectarse a una porcion (5 I) del elemento cilíndrico elongado (5) para proporcionar traccion del elemento cilíndrico elongado a lo largo del eje (6). Un dispositivo (4) para la rotacion del elemento cilíndrico elongado aplica una torsion al elemento cilíndrico elongado (5) sobre el eje (6) en forma simultánea con la traccion. También se divulga la planta para la produccion del elemento cilíndrico.
