Publication number: 20130186137Abstract: In a known drawing method for producing a cylindrical component from quartz glass, a quartz glass strand (2) is continuously drawn off from a softened quartz glass composition (13) vertically downwards in the drawing direction (3), a piece (15) with a weight G is detached from the free end of the strand at a time t1 and the cylindrical component is produced from the piece (15). When the piece (15) is detached, there may be a sudden reduction in weight, which leads to fluctuations in the thawing-off control. To counteract this, it is proposed according to the invention that a weight compensating force which acts counter to the drawing direction (3), increases over time and completely or partially compensates for the weight G of the piece (15), is applied to the piece to be detached at a time t0 before t1.Type: ApplicationFiled: June 29, 2011Publication date: July 25, 2013Applicant: HERAEUS QUARZGLAS GMBH & CO.
