Abstract
Described herein is a novel process for separating individual lubricated aluminum sheets from a stack of lubricated aluminum sheets as they enter a stamping press for fabrication. The process involves placing a lift underneath a stack of aluminum sheets and lifting the center upwards. This in turn causes the edges of the stack to bend downwards, creating a concave bending curvature facing the lift. The induced curvature is sufficient to provide the inter-sheet shear necessary to break the adhesion caused by the lubricant.
