Profile: R & E Kirwin Limited specializes in the design, manufacture and support of paper machine auxiliary equipment. We offer a full line of doctor blades, doctor holders and accessories. We are ISO 9001-2000 certified company. The Kirwin blade puller is a device specifically designed to provide a simple and safe method for doctor blade removal. It bites onto the doctor blade, then locks in place when the safety ring is secured, allowing for the safe removal of the doctor blade, even if using another extraction assisting device. Changing doctor blades is a major source of accidents in pulp and paper mills.
