ABSTRACT:
A method and apparatus for producing fibrous web pieces by die cutting the pieces from a continuous web. In the method, a fibrous web is provided having adjacent corrugations usually filled with a powder, and the powder-filled web is passed through a matched cutting die set intermittently which cuts and punches out the individual web pieces. Following the web cut out step, the web pieces are transferred downwardly onto a shuttle conveyor, and the pieces moved forward and simultaneously spread apart to permit subsequent convenient placement of the pieces. The cutting die apparatus includes matched punch and body die units which closely interfit with less than about 0.001 inch total clearance, so as to cut and punch out the fibrous web pieces from the continuous web.
