<p>A method and apparatus for edge sharpening a strip (30) that provides a doctor blade or a squeegee blade (e.g. for use in screen printing), wherein a rotary cutting blade (25) cuts through the strip (30) between the opposite major faces (32, 34) of the strip (30), and at fixed angles to said major faces (32, 34), whilst the strip (30) is moved longitudinally relative to the rotary cutting blade (25). The apparatus (which constitutes a strip blade edge sharpening machine) comprises a frame (20) and a support member (22) for the strip (30), said support member (22) being mounted on bearings (13) carried by the frame (20) so as to mount the support member (22) for rotary movement in a horizontal plane and maintain a fixed spacing between the support member (22) and the rotary cutting blade (24) as the strip (30) is carried by the support member (22) past the rotary cutting blade (25). Advantageously the apparatus comprises (a) a member having a cylindrical abutment surface (14), (b) means to hold said strip (30) with a major face against the cylindrical abutment surface (14) and with a minor face disposed longitudinally beyond one end of the cylindrical abutment surface (14) of said member, and (c) means (17, 18, 19) to rotate said member about the axis of said cylindrical abutment surface (14), said rotary cutting blade (25) being arranged to cut through the strip (30) between said minor face and said one end of the cylindrical abutment surface (14). e</p> |
