ABSTRACT:
A plurality of pairs of interengaging shearing blades on upper and lower jaws are maintained at distances and tilt angles from a reference line which separates the shearing into discretely acting zones. The distances and tilt angles produce vertical steps between ends of adjacent pairs of shearing blades relieve shearing forces to direct the shearing forces to other pairs of shearing blades, where the shearing force is needed. All shearing blades are identical and interchangeable, whereby only a single type of shearing blade must be manufactured and stocked. In addition, each of the four corners of each shearing blade is installable in a position for active operation, thereby prolonging the lives of the shearing blades. Longitudinal clearances between adjacent ends of shearing blades reduces shearing forces required as the shearing point passes off the ends of blades into the vertical steps.
