ABSTRACT:
Reverse contour changes, e.g., changes from a convex peripheral portion to concave peripheral portion are scored in a glass sheet by moving the glass sheet along an X-Y axes while pivoting a scoring wheel housing about an axis transverse to the first and second axes so as to positively rotate the housing in response to contour changes.
Further, a pattern cutter includes a sheet support which is mounted for movement along X and Y axes and about a pivoting Z axis relative to a stationary scoring wheel so as to positively control the scoring of the glass sheet during changes from convex portions to concave portions.
