Title: Glass cutting appts - for cutting blanks to different lengths for automobile windscreens
Inventor: KABANOV N P
IPC: C03B33/04
Filed: 1975-01-14
Abstract: In a glass cutting appts. comprising a template and cooperating driven cutter mounted above a vertically adjustable glass blank supporting table, the table is also displaced longitudinally relative to the parallel sides of the template in opposite directions during each successive cut.
