Abstract
Automatic cracking apparatus for cracking a glass plate along score lines extending across the plate. The apparatus has a vertically inclined main breaking roller where the top of the lower axial end of the roller is even with a feed conveyor and has an edge breaking roller for engaging an edge of the plate and the top of which lies above the highest point of the main breaking roller.
Claims11
Apparatus for the automatic cracking of score lines extending across a glass plate during travel of a plate through the apparatus with the apparatus comprising a horizontal feed conveyor, a discharge conveyor and a main breaking roller disposed between the feed conveyor and the discharge conveyor with the uppermost generatrix of the surface of the main breaking roller lying above the level of the feed conveyor and the discharge conveyor;
- the improvement characterized in that the main breaking roller is inclined vertically along its longitudinal axis whereby the uppermost generatrix of the surface of the main breaking roller at its lower axial end lies substantially at the level of the feed conveyor, and in having in addition an edge breaking roller positioned near the upper axial end of the main breaking roller adapted to engage one edge of a glass plate and whereby the uppermost generatrix of the edge breaking roller lies above the uppermost generatrix of the main breaking roller.
