Abstract

343,393. Sheet-perforating apparatus for printing-machines. NICOLAUS & CO., GES., H., Kempten, Allgau, Bavaria, Germany. April 26, 1930, No. 12930. Convention date, Nov. 25, 1929. [Class 100 (i).] The inclined feed-table e of a printing-machine is provided with punching- apparatus for perforating the sheets before they are printed. The punches f which are carried by an oscillating arm g coact with holes m in the table e to perforate the sheets o while they are being registered against a rising and falling front stop n. A spring-pressed collar i on each punch f having its outward movement limited by a stop l presses the sheet on the table e during the perforating operation and prevents it rising with the punch.
