Abstract
Abstract A plurality of scoring assemblies each having a scoring wheel are selectively positioned above and transverse to a glass sheet movement path and in spaced relation to a plurality of support assemblies. Each of the support assemblies are mounted on a common shaft for movement below the sheet movement path and include a laser mounted in predetermined spaced relation to a support wheel. Respective ones of the support wheels are aligned with their respective ones of the scoring wheel when the laser beam is incident on the center of a photodetector spaced from the scoring wheel. The support assemblies are moved into alignment with their respective ones of the scoring assemblies by rotating the shaft to move a selected one of the support assemblies into alignment with a selected one of the scoring assemblies while the remaining support assemblies are held stationary. The above is sequentially repeated to align the remaining ones of the scoring assemblies with their respective one of the support assemblies.
