Abstract

A system for use in a glass drawing process includes: a tensioning element; a refractory tube having a tubular element and a surface element, the refractory tube being configured so molten glass runs onto a contact surface area of the refractory tube during a glass drawing process, the contact surface area of the refractory tube being allocated at least in part on the surface element, the surface element covering at least one surface of an end section of the tubular element, and the surface element projects at least in part over the end section of the tubular element, at least one portion of the part of the surface element projecting over the end section of the tubular element being connected at least in part to the tensioning element; and a carrier that carries the refractory tube and is connected with the refractory tube in a non-rotating manner.
