BOOK BINDERY AND TRIMMING APPARATUS

摘要

Book bindery and trimming apparatus which is directly connectable to the output of a digital printer enables substantially automatic book production. Individual sheets (10) are cut from a printed web (3), folded and driven into a sheet stacker (15). The stacker (15) collects the sheets (10) onto a pair of vanes (21) mounted on respective drums until the end of a book is reached. At this point the stacker (15) is moved to its next position(s) and the sheets forming the collected book are deposited on a stack collector (16). Meanwhile, a new pair of vanes (21) present themselves for book collection. The collected book progresses through a stitcher (32), for wire stitching, and then to the trimming apparatus (34). The trimming apparatus (34) has a book path inclined downwardly towards a backstop (37) which, in cooperation with front stop fingers (37'), ensures reliable alignment of the book for trimming.
