Description

keligt og gjort strømningsdygtigt og plastisk flydende ved den forudbestemte fortætning af materialet, der komprimeres i beholderen. Skeletkonstruktionen (26) tilvejebringer således konstruk-tionsstivhed og indkapsler samt fastholder glasset (28'), indtil konstruktionen (26) knuses af pressestemplet (24), hvorefter det nu strømningsdygtige glas overfører tryk fra alle retninger til at bevirke den forudbestemte fortætning af materialet, der komprimeres i beholderen (12).
