ABSTRACT:
A method and apparatus for separating a single ply of limp material, such as fabric from a stack of such plies, and transporting the separated ply to a predetermined destination. The apparatus includes a rotatable ply gripping wheel, cooperating with a ply holding shoe. By rotating the wheel in contact with the ply, while restraining an adjacent area, the ply is buckled into a wave, nipped and then picked off of the stack. The gripping wheel and pressing shoe maintain a predetermined geometric relation, while being capable of independent yieldable contact with an uneven ply stack. The gripping wheel and holding shoe are operable in conjunction with an insertable flat plate, which is effective to progressively free the remainder of the ply. Thereafter, the flat plate is utilized to transport the freed ply to a desired destination, while the picking unit independently returns to the ply stack to commence its engagement with the next subsequent ply. Laterally movable sweep arms are provided as moving positioning abutments to secure the desired orientation of the ply at its destination.
