Abstract:
1. A system for handling sheets provided by an upstream source, each of the sheets defining at least one book page thereon, comprising: a drive that directs each of the sheets along a feed path in a downstream direction from the source, the drive including selectively actuable drive elements that engage each of the sheets to drive, disengage each of the sheets to allow non-interference therewith, at predetermined times; a first trimming station constructed and arranged to trim at least one edge margin strip from each of the sheets driven from the source; a rotator that selectively engages each of the sheets in a first orientation received from first trimming station and that rotates each of the sheets into an orthogonal, second orientation with when adjacent of the drive elements are disengaged; a second trimming station that receives each of the sheets from the rotator, the second trimming station constructed and arranged to trim at least one orthogonal margin strip for each of the sheets so as to form approximately page-sized sheets; and a stacker assembly, that receives each of the page-sized sheets and that stacks each of the page-sized sheets in a predetermined page order.
