This invention relates to a stacker mechanism for removing flexible work pieces from the working area of a machine. The stacker mechanism of the present invention includes a frame, an arm, and a support member having first and second pivotal connections. The first pivotal connection serves to rotatably secure the support member to the frame and allows the arm carried thereby to be vertically rotated. The second pivotal connection allows pivotal movement of the arm in a horizontal direction. The end of the arm opposite the second pivotal connection carries a wiper mechanism for engaging and moving the work piece. A driver is employed for pivotally moving the arm. A motion retarding assembly is provided at the second pivotal connection for applying frictional restraint to the horizontal turning movement of the arm whereby a higher coefficient of friction is maintained at the second pivotal connection relative the first pivotal connection. The difference between the coefficients of friction at the pivotal connections results in a rectangular motion being imparted to the wiper mechanism during operation of the stacker mechanism. A rotational support table is provided for maintaining intermittent support of the work piece.
