Verfahren und Vorrichtung zum Absprengen des Randbereiches ausserhalb der Ritzlinie einer Glasscheibe

摘要

The invention relates to a method and an apparatus for removing a marginal zone (10) external of an outline (7) cut in a glass sheet, in which method a glass sheet (6) is carried by means of a suction-padded (4) conveyor carriage (1) to a marginal zone removing station, wherein the marginal zone (10) to be removed is subjected to the action of a heating flame by means of a flame burner. During or after the flame heating, the removal of marginal zone (10) is secured by means of mechanical removing members (8) fixed to conveyor carriage (1) and brought to collide with a possibly unremoved edge zone (10) by moving suction pads (4) and removing members (8) relative to each other. Preferably vertically movable removing members (8) are fixed to suction-pad rods (5) for automatically setting them in a correct position in alignment with marginal zone (10) to be removed.
