  • Patent number: 7707853
    Abstract: In the process for partially shaping, a glass/glass ceramic article (5) is held on a planar support plate (1) by suction. The glass/glass ceramic article is heated to soften it, so that it has a viscosity below 106 dPa·s. After the softening one or more shaping dies (4) is or are moved upward through an opening or respective openings (3) in the support plate to form raised regions in the softened glass/glass ceramic article (5). The suction force is produced by a low pressure in a hollow compartment (2) below the support plate (1) and acts on the glass/glass ceramic article (5) by means of a gap (G) formed between each shaping die (4) and the support plate. Additional openings can be provided in the support plate and/or in one or more of the shaping dies to assist in applying the suction force to the glass/glass ceramic article. After solidification of the softened glass/glass-ceramic article the shaping die or dies (4) is or are withdrawn.
