Abstract

A heating oven is provided for processing glass materials from which optical waveguide fibers are prepared. The oven includes a vertically oriented, elongated cylindrical muffle for receiving the glass material which is to be processed. The supporting structure for the upper end of the muffle is thermally independent of the supporting structure for the remainder of the oven. In this way, the expansion and contraction of the muffle can be compensated for independently of the expansion and contraction of the oven's main support frame.
