摘要

Arrangement for producing quartz glass rollers comprises a burner (12) which moves between two reversing points (121, 122) according to a path-time law on a spatial curve so that during this movement the burner opening (17) is located always at the same distance from the cap (16) of the roller (14) and the burner axis is always directed toward the middle point of the cap.
