APPARATUS FOR AND A METHOD OF PRINTING, BINDING AND TRIMMING A PRINT ON DEMAND PERFECT BOUND BOOK

摘要

Apparatus for printing, binding, and trimming print on demand (POD) perfect bound books is disclosed in which a plurality of sheets are accumulated on an accumulator so as to form a book block. The accumulator is initially in an inclined position so as to receive the sheets and to form the book block. Upon the book block being formed, the book block clamp is clamped to the accumulator and the accumulator is moved from an inclined to a vertical position and is moved downwardly along a workpath to an adhesive application station having a spine roughener and an adhesive applicator. The adhesive application station is moved relative to the stationary book block so as to roughen the spine of the book block and to apply adhesive to the spine. Then, the accumulator moves the book block downwardly along the workpath to a binding station at which the spine of the book block is adhesively bound to a cover positioned at the binding station. Then the bound book is moved down through the binding station to a trimming station. This downward movement of the book block and book along the workpath results in a more compact apparatus.
