Abstract

1,064,587. Making dies; making machine knives. M. D. MARTIN. Sept. 21, 1964, No. 38440/64. Heading B3A. [Also in Division B4] A method of making a die rule for a rotary cutter device includes the steps of providing a metal strip with a longitudinal cutting edge and a base edge, forming spaced notches transversely in the base edge of the strip,. bending the strip to the required contour and then forming the rule to a curvature corresponding to the radius of rotation of the rule about the axis of the rotary cutter by heating the base of each notch in turn and narrowing the mouth of the notch. The rule so formed is mounted by providing a primary base bent to the required curvature, forming slits through the base in a pattern conforming to the contour of the die rule, pressing the die rule into the slits so that the cutting edge protrudes from the convex face of the primary base and mounting the primary base on a curved secondary base adapted to be secured to the rotating member of the rotary cutter device. The strip 1 has a cutting edge 2, and a base edge 3 having legs 7 formed by notches 8. The notched strip is bent to the required contour, Fig. 2 (not shown) and then formed to the required curvature, Fig. 4, by heating the base 9 of each notch and applying pressure to the legs. The primary base (11), Fig. 7 (not shown), is formed of laminated wood and slotted at (14) to receive the legs 7. To increase the frictional grip of the legs they are bent out of the plane of the strip alternately in opposite directions, and may be bifurcated. The primary base (11) is then mounted on the secondary base (12), Fig. 8 (not shown) by screws (19). Prior to assembly the mating surfaces are coated with a releasing agent such as a silicone wax and a layer of cold-setting epoxy resin is applied between the faces to ensure perfect seating. In a modification the slots (14) are contiguous and the plug removed is replaced after the rule has been inserted in the aperture and is retained by a screw.
