| 05/19/1994 | DE4238948A1 Glass pressing plug with thin skin - which deforms under heat and pressure to avoid seam formation AB DE4238918A Glass moulding plug has a thin e.g. 0.3-0.5 mm thick skin which, because of 0.3% heat and 0.2% tension expansion, is sepd. from the core plug by a pressure medium after or shortly before the plug comes to rest. Pressure medium is supplied through bores (2,3,7) also for removal of heat and thus removal of deformation after the plug is sepd. from the glass.
