Set binding, stapling and stacking apparatus

摘要

Apparatus is provided for receiving and assembling sheets in a binding station at which thermal binding strips are automatically supplied to the side edges of the assembled sets, the sheet receiving trays at the binding station are laterally moved apart to allow a set of assembled bound or unbound sheets to gravitate to a stapling station at which an assembled set of sheets may be stapled together, and the trays forming the stapling station are moved laterally apart to allow the stapled set to gravitate to a stacker tray which is allowed to move downwardly as progressive sets are deposited on the stacker tray and the stacker tray is moved upwardly to a set receiving position following removal of finished sets.
