Abstract

A process for grinding serrated cutting edges on a moving blank steel band comprises moving two cooperating grinding heads towards and away from the blank steel band, each grinding head carrying at least one grinding wheel. Each grinding head may comprise up to seven grinding wheels which may be driven independently at a closely controlled constant speed by an electric motor. The axes of the grinding wheels may be parallel with the axis of the blank steel band. The travel of the grinding wheels towards the blank steel band and the time the wheels remain in any one position determine the shape of the serrations. The serrated cutting edge may be formed in a single pass. The grinding heads may be moved independently by servo motors and controlled by computer. The cutting edges may be formed on a knife or a saw. Also disclosed is a serrated cutting edge characterised by flattened out gullet bottoms and flattened tips (fig. 5), the edge being advantageous for cutting foam and similar stiff, low resistance materials.
