ABSTRACT:
In the process of producing brochures such as account books, textbooks, notebooks and chits, a back-splitting operation which has hitherto been performed by hand is mechanically executed in such a way that a back-splitting cutter knife is attached to a turnable chain and that the cutter knife is thrust into the back portion of sheets of paper for the brochures, whereby the productivity of the process is enhanced and a sharp reduction in the cost thereof is achieved.
