A device for separating and stripping waste material from a blank during a carton or envelope manufacturing process is provided. The device includes first and second separating cylinders. At least one pin and sleeve assembly is coupled to the second separating cylinder, and includes a pin having a sleeve slidably coupled thereto. A tube or hollow bar is coupled to the separating cylinder, and has at least one aperture therein generally aligned with the pin and sleeve assembly. In separating the waste material from the blank, the pin couples the waste material to the second separating cylinder. A fluid such as compressed air is forced into the tube and directed through the aperture to slide the sleeve from a retracted position in which the pin is exposed to an extended position in which the pin is concealed, whereby the waste material is forcibly removed from the pin.
