ABSTRACT:
A precrush tool immediately precedes a slotting blade in a slotting tool assembly. The slotting blade is mounted in the same way as a conventional slotting blade with the exception that the top is profiled to give gradual crushing during rotation. The tool's area gets successively larger to the point that the top land equals the width of the slotter blade and its O.D. when mounted is effectively the pitch circle of the tool assembly. This design allows for the air to be removed from the board gradually and produces a sharp clean cut by the slotter.
