Abstract

Zum partiellen Umformen einer Glasplatte, die optional in eine Glaskeramikplatte keramisiert werden kann, sind verschiedene Formgebungsverfahren bekannt geworden, so auch das Verformen durch Schwerkraftabsenken. DOLLAR A Um mittels dieses Verfahrens Umformungen mit hohen Umformungsgraden durchführen zu können, sieht die Erfindung vor, daß in der Glasplatte (1) vor dem partiellen Umformen in dem vorgegebenen Teilbereich entsprechend seiner Kontur eine Materialverjüngung (3) angebracht wird. DOLLAR A Diese Materialverjüngung unterstützt die Umformung im beachtlichen Maße. DOLLAR A Die nach dem erfindungsgemäßen Verfahren hergestellten Glas- bzw. umgewandelten Glaskeramikplatten finden vorzugsweise als Kochflächen oder Kaminsichtscheiben Anwendung.For partially forming a glass plate, which can optionally be ceramized in a glass ceramic plate, various shaping methods have become known, as well as the deformation by gravity lowering. DOLLAR A in order to carry out by this method transformations with high degrees of deformation, the invention provides that in the glass plate (1) before the partial forming in the predetermined portion corresponding to its contour, a material taper (3) is mounted. DOLLAR A This material rejuvenation considerably supports the forming process. DOLLAR A The glass or converted glass ceramic plates produced by the process according to the invention are preferably used as cooking surfaces or chimney windows.
