Abstract (en)
[origin: DE19952474C1] The first front-side end (6) of the mandrel (1) terminates in an inner bore (7) of a first holder (8), and the holder rotates using a first bearing element (10). Apparatus for producing a quartz glass body comprises: (a) a longitudinal mandrel (1) that rotates about a horizontal orientated axis (4); (b) a burner (11) which deposits layers of silicon dioxide particles on the casing surface of the mandrel forming a porous green body (13); (c) a first holder surrounding the mandrel in the region of one the ends of the green body; and (d) a fixing element which connects the mandrel and the first holder. An Independent claim is also included for a process for the production of a quartz glass body using the above apparatus.
