ABSTRACT:
Back-splitting apparatus for use in the production of books such as account books, notebooks, textbooks and the like for separating a block of stacked sheets of paper, bound together at one side by gluing and constituting a plurality of books, into individual books. A plurality of projection pieces are provided at one sides of the final sheets of the respective books of the block. A suction member is disposed at the position faced with one of the projection pieces, and a pawl member is disposed movably to the lower portion of the suction member. The block of stacked sheets of paper is separated into individual books accurately by advancing a back-splitting cutter knife into the back surface side of the projection piece interposed between the suction member and the pawl member. Thus, this apparatus can effectively separate a block of stacked sheets of paper made of thick and extremely thin sheets.
