Abstract
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 misorientated prior to entry into a shaping station. However, the invention is also capable of use with any type of conveyor defining an elclosed conveyor path for said glass sheets where the glass is liable to lose its orientation and/or alignment and must be orientated and/or aligned preparatory to processing.
