The granted patent (Publication Number: US11911925B2) discloses a method for automatically adjusting the cutting gap of a slicing machine used for slicing strand-shaped product calibers from food products into slices. The method involves controlling a blade motor that drives a blade with a peripheral cutting edge in cooperation with a cutting frame. The adjustment process includes monitoring changes in rotation speed during a complete blade revolution and adjusting the current supply to the blade motor accordingly. If the rotation speed deviates beyond a specified tolerance, the current supply is increased or decreased until the rotation speed falls within an acceptable range.

Furthermore, the method includes additional steps such as carrying out multiple blade revolutions to ensure the idle torque remains stable, setting specific approach rates for the cutting frame movement, and conducting automatic adjustments after each movement of the cutting frame. The method is designed to operate within a rotational speed range of 50 to 500 rpm and includes criteria for determining significant increases in idle torque within one blade revolution. Overall, the patent outlines a comprehensive process for precise and automated adjustment of the cutting gap in slicing machines, enhancing efficiency and accuracy in the slicing of food products into uniform slices.
