Abstract (en)
[origin: US4647033A] A conveyor for sheets fed to or from a printing press in an overlapped stream, the table having longitudinal slots formed therein laterally spaced from one another. A perforated endless conveyor belt is trained over the table. An enclosed chamber extending substantially the length of the table communicates directly with the slots, the chamber being convergently shaped terminating at its lower end in a throat. An axial flow fan in the throat draws air through the perforations so that a stream of overlapped sheets on the belt will be held in contact therewith for transport from one end of the table to the other. The fan is chosen to have a flow characteristic such as to maintain the pressure differential across the fan approximately constant notwithstanding variations in the rate of air flow resulting from gaps in the stream. The belt is in two narrow, laterally spaced sections dimensioned to fit into the slots.
