Abstract
A machine cambering glass plates as a curved shaping bed formed of vertically aligned pairs of rollers. Each roller of each pair has an end mounted to a pivoting arm so that it can be elastically bent in a middle portion thereof, while keeping the ends of the rollers straight. Needle bearings support the rollers in the bending plane. The support arm for the lower roller supports the support arm for the upper roller, so that the two pivot together so as to provide uniform bending for the upper and lower pairs of rollers.
Claims14
A shaping roller assembly in a cambering installation for glass plates, comprising:
- a first cylindrical bending rotatable about the longitudinal axis thereof;
- and
- means for elastically bending said roller between two secant planes perpendicular to said axis, said planes intersecting said roller adjacent the ends thereof;
- means for vertically displacing a distal end of said first support arm;
- and
- a second cylindrical roller positioned vertically over said first roller and a second support arm,
- wherein the ends of the elastically bent roller remain straight, and wherein said second support arm cooperates with said first support arm such that said means for displacing said first support arm simultaneously displaces said second support arm.
