Abstract
Apparatus for removing and disposing of scrap paper chips impaled on a roller rotating away from the cutting region of a rotary cutter has a pneumatic baffle plate located a distance of 3/8 to 11/2 inches away from the roller, defining a narrow flow channel through which an air stream is sucked by a centrifugal fan. The baffle is spaced apart from the roller a distance such as to impart a high velocity to the air stream due to aerodynamic effects, causing chips to be forcibly removed from the roller when the chips reach an area above the flow channel. The baffle along with a chute that supports it and duct leading to the fan provide an enclosed channel for movement of the chips. The baffle edge adjacent the roller is provided with a curved surface to provide smooth flow of the air stream. The output of the fan has an air duct connected for conveying the chips to disposal.
