Abstract

Method and apparatus for nondestructively removing a cut segment of predetermined shape from a limp material sheet workpiece and transporting the cut workpiece segment to a staging area for further processing. The cut segment is picked up by a picker which may comprise an array of carding strips, each strip having a plurality of needle-like elements, arranged such that each strip can be displaced relative to its adjacent strips and the needle-like elements of each strip are angularly offset with respect to the needle-like elements of the adjacent strips. Such removal and transporting having is accomplished without distorting the shape of the cut segment.
