STACK FEEDING AERATION DEVICE AND METHOD

摘要

An aeration device adapted to aerate one or more sheets of a stack of sheets includes a side blower configured to selectively provide an air stream at an outlet thereof along an airstream direction so as to impinge against at least a portion of the stack. A height detecting device is configured to detect a height of an uppermost sheet of the stack. A side blower adjustment device is configured to adjust a height of the side blower and/or an angle of the airstream direction so as to track, by the air stream, the uppermost sheet of the stack based on an input from the height detecting device.
