Book binding processes require the precise positioning of folded multi-page sections "booklets" from a fixtured conveyor in a gatherer section thru an intermediate pocket conveyor and then into a binding section. A MS332 is used to control the positioning of the fixtured conveyor to the infeed conveyor. The gatherer conveyor deposits the booklets vertically into the infeed conveyor which then hands the booklet off to a spring loaded pocket in the binder. Then, the binder carousel carries the booklets to a rotary knife for trimming, a glue section and a cover applicator.
