Abstract

The present invention is directed to a device for separating a stack of flexible, planar material such as cloth, comprising a fixed set of pins and an adjustable set of pins, where the adjustable set of pins follows a downwardly curved path of motion to create a fold in the top layer of the stack of so that this layer may be conveniently lifted off without lower layers adhering to the top layer.
