ABSTRACT:
Apparatus for aligning and orienting moving glass sheets immediately prior to their treatment. This invention is especially suitable for use with glass sheets heated while conveyed through a furnace on a roller conveyor where the glass becomes misaligned or misoriented prior to entry into a shaping station. However, the invention is also capable of use with any type of conveyor defining an enclosed conveyor path for said glass sheets where the glass is liable to lose its orientation and/or alignment and must be oriented and/or aligned preparatory to processing and is also suitable to orient and align rigid sheets other than glass.
The apparatus includes a pair of truncated conical rollers which engage the edge of the glass sheet and, due to their shape, substantially reduce chipping thereof. These rollers are mounted on a carriage in a manner to permit lateral movement relative to the carriage by cams. The carriage reciprocates along the path in a manner to move with the sheets. As the carriage returns, the glass engaging rollers are raised and laterally retracted so as to avoid contact with the oriented glass sheet.
