| 20110008132 | Cover Conveyor For Perfect Binding Machine - A method and apparatus for sequentially delivering book or magazine covers of the same or differing width dimension to a perfect binding system such that books or magazines of differing size can be produced without requiring system downtime for resetting of cover guiderail settings. Associated with each cover size is a cover feeder arranged to deliver covers therefrom, one a time, between members of a given pair of guiderails that are assembled in stacked parallel relationship on the bed of the cover conveyor. Under control of a microprocessor-based controller, covers of a predetermined size arrive at the gluing station of the perfect binder in synchronism with signatures of a selected size corresponding to the cover to be applied. | 01-13-2011 |
