ABSTRACT:
A hot forming unit or debiteuse for plate glass production, with a noble metal box or frame encompassed by and contained in a highly heat-resistant ceramic frame and having a drawing slot matched to a cross section of a plate glass sheet to be produced. The dimensional integrity of the drawing slot of the noble metal frame is assured because the ceramic frame is constructed of longitudinal components and lateral components, where the longitudinal components of the ceramic frame and the longitudinal legs of the noble metal box rest against one another and are held so that they can still move axially against each other in a limited fashion. The longitudinal legs of the noble metal box are held in a stretched position by tension springs.
