Book bindery and trimming apparatus which is directly connectable to the output of a digital printer enable substantially automatic book production. Individual sheets are cut from a printed web, folded and driven into a sheet stacker. The stacker collects the sheets onto a pair of vanes mounted on respective drums until the end of a book is reached. At this point the stacker is moved to its next position(s) and the sheets forming the collected book are deposited on a stack collector. Meanwhile, a new pair of vanes present themselves for book collection. The collected book progresses through a stitcher, for wire stitching, and then to the trimming apparatus. The trimming apparatus has a book path inclined downwardly towards a backstop which, in cooperation with front stop fingers, ensures reliable alignment of the book for trimming. |
