METHOD OF FORMING A FLAT GLASS INTO A GLASS COMPONENT AND FORMING TOOL FOR USE IN THE METHOD
A method for forming a flat glass into a glass component, the glass component comprising a base surface and provided with a number of formations for forming surface structural elements that can be felt by a user, is intended to ensure a particularly high mechanical load-bearing capacity of the glass component or moulded part in a particularly simple and reliable manner, even in the case of comparatively complexly configured structural elements. For this purpose, according to the invention, the flat glass is placed in a forming tool on a number of forming plungers corresponding to the intended formations and then heated to soften the material, so that the glass material assumes the contour of the base of the forming tool between the forming plungers for forming the base area.

7 . A method of forming a flat glass into a glass component, the glass component comprising a base area and provided with a number of formations intended to form surface structural elements which can be felt by a user, in which method the flat glass is heated in a forming tool so as to soften the material and, before or during the forming which thereby occurs, the flat glass comes to rest on a number of forming plungers corresponding to the intended formations, wherein the glass material assumes the contour of the base of the forming tool between the forming plungers for forming the base area, wherein during the forming of the glass material a transverse flow of material towards the side flanks of the forming plungers is produced in that during the forming of the glass material the forming tool is heated less in the region of its forming plungers than in the bottom regions therebetween.
8 . The method of claim 1 , wherein the transverse flow of material is promoted by the use of a forming tool, the tool base of which is provided at least in sections with a friction-reducing coating, preferably graphite or boron nitride.
