<p>PCT No. PCT/FR95/00551 Sec. 371 Date Oct. 25, 1996 Sec. 102(e) Date Oct. 25, 1996 PCT Filed Apr. 27, 1995 PCT Pub. No. WO95/29046 PCT Pub. Date Nov. 2, 1995Sheet materials in the form of remnants of non-repetitive shapes and that might be flawed, e.g. hides (10), are cut up using a method that includes the following operations: digitizing the geometrical shape of each remnant; defining a layout for pieces to be cut out from the remnant; and cutting out the pieces from the remnant in compliance with the resulting layout. The surface of the remnant (10) is provided with marks characteristic at least of the disposition and of the orientation of the remnant during digitization. The marks are detected so as to generate and record position information representative of the positions of the first marks. At the cutting-out station (300), images of the marks in the positions defined by the recorded first position information are projected onto a work surface, and the corresponding remnant is placed on the work surface by bringing together the marks carried on the surface of the remnant and their projected images, so as to cut out the pieces from the remnant in a disposition and an orientation similar to those which it had during digitization.</p> |
