Abstract
Abstract A vitreous ceramic cooker hob plate with circumferentially surrounding frame permanently elastically adhesively fitted thereto is provided. The circumferentially surrounding frame is adhesively joined to the hob plate in such a way that a narrow gap is left between the bevelled edge of the frame and the hob plate, and the frame flange overlaps the same. The gap is filled in, flush with the frontal side of the bevelled edge, by a permanently elastic adhesive which makes a sealed and mechanically firm joint between the bevelled edge and the hob plate.
