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.
