Abstract:
A process of bindery compaction in a bindery with a compactor wherein the compactor includes:a receiver having an opening for receiving paper waste crowded into the opening; a chute having a bottom, two parallel sides and an open top to receive waste material and extending from the opening of the receiver away from the receiver to define a volume to be compacted, the chute ending at the opening of the receiver; a platen extending between the two parallel sides of the chute and moveable along the chute over the bottom of the chute for crowding material placed into the open top of the chute into the receiver; an expandable ram fixed relative to the chute away from the opening of the receiver and expandable along the chute for moving the platen during crowding of the waste material from the chute into the receiver; and, a plate for sealing the open top of the chute behind the platen and over the expandable ram when the platen is moved forward along the chute to crowd material into the receiver; the process including the steps of: providing a first bin formed overlying the chute having a first bin bottom occupying less than a full area of the open top of the chute; providing a second bin formed overlying the chute having a second bin bottom occupying a remainder of an area of the open top of the chute; maintaining the platen normally forward in the chute to close the opening the receiver; at least partially filling one of the bins; at least partially retracting the platen from the normally forward position to open the chute to receive material from either the first bin or the second bin for crowding into the receiver; and, returning the platen to the normally forward position to crowd and compact material received in at least one of the bins into the receiver.
