Abstract
Stacking of a large number of delicate and easily damaged flexible lamina with highly accurate registration is automated by use of an alignment fixture having alignment pins and a stacking plate. The stacking plate is raised to and frictionally supported at a location near a tapered shoulder portion of the alignment pins on which each of a plurality of lamina is allowed to self-align. A floating head which may be used to transport lamina to the alignment pins is also self-aligned with the alignment pins and used to press the individual lamina over the alignment while maintaining precisely parallel orientation and motion of the lamina to the lamina stack and the stacking plate. The stacking plate is moved against the frictional support thereof to maintain a short effective alignment pin height or protrusion above the stacking plate or lamina stack to prevent binding or wiping motion between lamina and resultant damage of the lamina.
