333,818. Uttenweiler, H. Nov, 3, 1928, [Convention date]. Printing processes.-In a process for printing on duplicate or manifold forms, two or more sheets or webs and interposed carbons are fed together to a printing-machine, the top sheet or web receiving an ink impression and the others a carbon impression. Instead of interposed carbons, the sheets or webs may have carbon-coated backs. The process ensures register of the printed matter and of the lines, so that when the forms are filled in the writing or typing appears in the correct position. In the arrangement shown in Fig. 2, paper webs d', f<1> and a carbon web e<1> pass from rolls a<1>, c', b<1> or a single roll and through a printing-couple g<1>, h<1>, the webs d<1>, f<1> receiving ink and carbon impressions respectively. The webs may be perforated and wound on a roller i<1>, or may be cut into sheets which may be bound together. In another arrangement two sheets of paper and an interposed carbon sheet are fed from a take to a flat-bed printing-machine, and are carried by a conveyer to another table.
