Abstract: An apparatus and method are provided for trimming a print sheet and registering the location of an image on the print sheet. The apparatus may include a sensor system arranged to detect a guide line on the print sheet to align the print sheet relative to a cutter. The sensor system emits first and second light beams through the print sheet, and a controller is configured to detect the presence of the guide line through the light beams to align the guide line on the print sheet relative to the cutter. The apparatus may also include a vacuum chamber extending through a plate, with a float positioned within the vacuum chamber. In a first configuration, a vacuum is drawn in the chamber moving the float within the vacuum chamber away from the base such that a print sheet is moveably receivable between the plate and the base.

Abstract: An apparatus for producing hard book cases (covers) can make cases including tucked and folded corners. The apparatus can track the progress of the book case throughout the assembly process and can accurately align the unfinished assembly with the tucking and folding devices of the apparatus. Short runs of different sized book cases may be quickly and efficiently manufactured on a single apparatus.
