摘要： 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.
摘要翻译：用于生产书籍，笔记本，教科书等的书籍的分割装置，用于将通过胶合并构成多本书籍的一侧捆绑在一起的堆叠的纸张块分离成单独的书。多个突出片设置在块的各个书籍的最终片材的一侧。抽吸构件设置在面对其中一个突出件的位置处，并且棘爪构件可移动地设置到抽吸构件的下部。通过将分解后的切割刀推进插入在吸引构件和棘爪构件之间的突出片的背面侧，将堆叠的纸张块精确地分离成单独的书本。因此，该装置可以有效地分离由厚而非常薄的纸制成的堆叠的纸张块。
