PROCESS AND APPARATUS FOR THE PRODUCTION OF A CYLINDRICAL COMPONENT OF GLASS

To produce a cylindrical glass component the softened glass mass is heated or cooled locally at least at one shaping section (18), according to the established deviation of the cross section geometry from a nominal geometry of the component (12). The shaping section (18) extends over only a part of...

Zusammenfassung:	To produce a cylindrical glass component the softened glass mass is heated or cooled locally at least at one shaping section (18), according to the established deviation of the cross section geometry from a nominal geometry of the component (12). The shaping section (18) extends over only a part of the circumference of the shaping zone (14). Also claimed is an appts. with a heating/cooling medium (4) acting locally on at least one shaping section (18) which extends over only part of the circumference of the shaping zone (14).
