ABSTRACT:
In the hitherto known apparatus removal of the flash, i.e. of the remaining portion of a glass sheet is effected by means of abutment rods which are vertically reciprocable and adapted to exert downward pressure upon the flash. A characteristic feature of the disclosed apparatus is that the abutments therein are so arranged and mounted on the frame that they are capable of complex motion i.e. of moving simultaneously downwardly and from the center of the support table toward the edges thereof. Owing to this characteristic feature of the abutments separation of the flash is effected mainly on account of its being pulled sidewise, which prevents formation of cracks and broken edges in the shape cut out from the sheet, which is sometimes the case when the flash is separated by the action of purely vertical loads.
