Patent ID: 8584491

Claim:
A drawing method for producing cylindrical components of quartz glass, said method comprising: drawing off a quartz glass strand in a direction of a drawing axis from a shaping zone of a quartz glass mass and repeatedly separating sections each having a respective separating length from the quartz glass strand and an end diameter, wherein each of the separating lengths is substantially equal to a cutting length, and producing the cylindrical components from the sections, wherein the quartz glass strand is separated at a separation position that is at a distance from a position in the shaping zone at which the quartz glass strand has a diameter that is 20% greater than the end diameter, and the method further comprising setting the distance of the separation position from the position in the shaping zone based on the cutting length, wherein the separation position is selected such that the quartz glass strand obtained from the quartz glass mass has a length between the position in the shaping zone and the separation position that is one time or a plurality of times the cutting length, and such that a disorder in the quartz glass strand geometry caused by the separation, in a subsequent separation step, is located in an end region of one of the components or between two of adjacent components.
