ABSTRACT:
The sheet binding apparatus is comprised of a movable binder assembly including an endless belt and an elongated heat application platen underlying one belt run. The belt is coated with a hot-melt adhesive, which, when heated by the platen, is applied by the belt to the co-planar sheet edges of one or more stacks of sheets assembled within individual bins of a collator. A belt lifting assembly controls heat transfer between the platen and belt by appropriate positioning of the belt with respect to the platen. The binder assembly is movable reciprocatively toward a sheet contacting binding position along a path perpendicular to the coplanar sheet edges. That assembly is further movable reciprocatively toward one or more additional binding positions along a path parallel to the coplanar sheet edges. In a second preferred embodiment, the binder assembly is swung along the first path by lost motion hinges.
