BLOCKS IN THE FRAME PROVIDE GUIDE SURFACES WHICH ARE CONVERGENT IN THE DIRECTION OF MOVEMENT OF THE WORK. WORK ENGAGING SHOES ARE SLIDABLE ALONG THE CONVERGENT GUIDE SURFACES SO AS TO CROSS-SECTIONALLY REDUCE THE WORK AS IT PASSES THROUGH THE FRAME IN STEP-BY-STEP MANNER BY RECIPROCATION OF THE SHOES. WEDGES ARE SLIDABLY INTERPOSED BETWEEN THE FRAME AND THE BLOCKS TO MOVE THE SHOES TRANSVERSELY INTO AND OUT OF ENGAGEMENT WITH THE WORK.
