Abstract
The invention uses a carriage that is longitudinally displaceable with respect to a cutting table, and a light transporting band whose width is at least equal to that of the sheets. The carriage is comprised of two separable movable members, one of which is motorized and comprises an image device for recording an optimized disposition of pieces to be cut out, while the other is towed and comprises a transversal clamping device into which is engaged a free end of the sheet. The towed member is coupled at its rear portion to the light transporting band, the latter serving to support and protect the sheet of patterned material when it is being drawn out.
