Abstract
A profile control for a shear mechanism of a glass processing machine eliminates cams, gears, etc. otherwise required to oscillate the shear mechanism arms in unison in opposite directions between open and closed positions. The profile is the angular position time curve of the arms as they open and close over a predetermined angular displacement. The profile is controlled by adjustable oscillators and programmable memory (PROM) which determine the commands to a reversible dc motor drive. The control synchronizes the movement of the arms in proper phase relationship with respect to the feeder mechanism of the glass processing machine.
