Dynamic regulation of contact pressures in a blade sharpening system

A system, comprising:

• an orbital blade to be sharpened, the orbital blade for sawing logs of paper or rolls of paper;
• a grinding wheel for sharpening the orbital blade;
• a pneumatic tensioner coupled to the grinding wheel;
• an air pressure regulator in communication with the pneumatic tensioner for regulating a varying contact pressure between the grinding wheel and the orbital blade during the sharpening;
• a processor for sending control signals to the air pressure regulator for regulating the varying contact pressure between the grinding wheel and the orbital blade during the sharpening, the regulated varying contact pressure for grinding a cutting edge of the orbital blade at a bevel angle of the grinding wheel with respect to a plane of rotation of the orbital blade;
• logic or executable instructions causing the processor to:
• count revolutions or saw cuts of the orbital blade;
• send the control signals to the air pressure regulator in communication with the pneumatic tensioner to apply the intermittent contact pressure between the grinding wheel and the orbital blade to be sharpened;
• wherein sharpening intervals during application of the intermittent contact pressure each comprise a first number of revolutions of the orbital blade based on the counted revolutions or saw cuts;
• and
• wherein non-sharpening intervals during application of the intermittent contact pressure each comprise a second number of revolutions of the orbital blade interleaved with the sharpening intervals, based on the counted revolutions or saw cuts.
