    Abstract: 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). Some glass-ceramic materials may also be suitable for the tubing, such as transparent beta spodumene.

    Abstract translation: 用于制造具有期望的非圆形横截面轮廓(参见图3)的玻璃管(200)的设备(100)包括适于定位靠近热软管的心轴(101)。 心轴(101)具有鼻部(102)和具有选定轮廓的喷嘴部分(120),其将限定管道的最终横截面轮廓。 喷嘴部分(120)具有用于从源(207)和多孔和/或有孔圆周表面(132,134)接收气体的进料腔(140),气体可以通过该进料腔排出到心轴的外部。 气体排放到心轴的外部,在多孔圆周表面(132,134)和热软管(200)之间的间隙(314,318)中形成加压气体薄膜。 还提供了使用该装置形成具有非圆形横截面轮廓的管道的方法。 还公开了由重塑或形成的管制成的玻璃套管:由用于电子设备(参见图13)的由平行的,相对的,平坦且光滑的前盖和后盖制成的整体式套筒。 一些玻璃陶瓷材料也可能适用于管道,如透明β锂辉石。
