    • Zur Herstellung eines Quarzglas-Großrohres sind mehrstufiges Umformverfahren bekannt, bei denen in einem ersten Formschritt unter Einsatz eines Formwerkzeugs ein Zwischenzylinder aus Quarzglas mit einer Zwischenzylinder- Wandstärke und einem Zwischenzylinder-Außendurchmesser geformt und anschließend abgekühlt wird, und in einem zweiten Umformschritt mindestens ein Längenabschnitt des abgekühlten Zwischenzylinders einer Heizzone zugeführt, darin zonenweise auf eine Erweichungstemperatur erhitzt und um seine Längsachse rotierend zu dem Quarzglas-Großrohr mit einer End-Wandstärke und einem End-Außendurchmesser umgeformt wird. Geometrieschwankungen nehmen mit dem Außendurchmesser des Endrohres exponentiell zu. Um Hiervon ausgehend ein Verfahren anzugeben, das bei wirtschaftlich vertretbarem Aufwand die Herstellung von Quarzglasrohren erlaubt, die auch bei großem Außendurchmesser von mehr als 500 mm eine hohe Maßhaltigkeit haben, wird erfindungsgemäß vorgeschlagen, dass das Quarzglas synthetisch erzeugt ist und einen mittleren Hydroxylgruppengehalt von 10 Gew.-ppm oder weniger hat, mit der zusätzlichen Maßgabe, dass bei Unterteilung des Zwischenzylinders in Längenabschnitte mit einer Länge von 1 cm, benachbarte Längenabschnitte in ihrem mittleren Hydroxylgruppengehalt einen Unterschied von weniger als 2 Gew.-ppm aufweisen.

    • An apparatus (100) for making glass tubing (200) of a desired non- circular cross-sectional profile (cf Fig.3) includes a mandrel (101) adapted for positioning proximate heat-softened tubing. The mandrel (101) has a nose (102) and a nozzle section (120) with a chosen profile that will define a final cross-sectional profile of the tubing. The nozzle section (120) has a feed chamber (140) for receiving a gas from a source (207) and a porous and/or foraminous circumferential surface (132,134) through which the gas can be discharged to an exterior of the mandrel. The gas discharges to the exterior of the mandrel, forming a film of pressurized gas in the gap (314, 318) between the porous circumferential surface (132,134) and the heat-softened tubing (200). A method of forming tubing having a non-circular cross-sectional profile using the apparatus is also provided. A glass sleeve made from the reshaped or formed tubing is also disclosed: a monolithic sleeve made of parallel, opposite, flat and smooth front and back covers for use in an electronic device (cf Fig.13).
