ABSTRACT:
Ribbons of scrap paper are pneumatically conveyed through a conduit into an enlarged chamber where the air velocity is reduced and the paper deflected downward to a hopper at the bottom of the chamber where it is gathered and baled for reclamation. The conveying air is filtered to remove dust and is then reused. Multiple conduits for carrying contaminated and uncontaminated paper scraps can be coupled to a chamber which is sectioned by a perforated divider which keeps the paper separated but allows the air pressure to be the same in the sections. A switch at the chamber input may also be provided to selectively feed the output from the multiple conduits into one or separate sections of the chamber.
