| titleOfInvention | Method and apparatus for reforming glass tubing by drawing over a mandrel to produce a flattened hollow sleeve |
| abstract | A reforming mandrel and a method of using it to reform glass are described. The reforming mandrel 100 comprises an upstream portion 120, a downstream portion 140 and an at least partially hollow interior 160. The upstream portion has an intake inlet 122 for fluid flow. The downstream portion 140 is axially spaced from the upstream portion 120. The downstream portion 140 has a flattened cross-section defined by flattened peripheral portions 142 joined by curved peripheral portions 144. At least one curved peripheral portion is made of porous material resistant to a temperature of at least 1000 °C, e.g. graphite. The at least partially hollow interior 160 of the mandrel communicates with the intake inlet 122 and the porous material. The hollow interior may extend into further hollow passages 170,172,174,176. A substantially cylindrical glass tube 400 is reformed by drawing the heat-softened tube over the mandrel 100, fed with gas, to prevent adhesion to the shaping tool, via the porous material to form a gas cushion, and so to reform its shape into a 3-dimensional formed glass sleeve with a flattened portion, without imperfections such as streaks. Of particular use in making a glass cover (integrated front and back) for a smartphone or similar device. |
