ABSTRACT:
The nibbler apparatus comprises a quickly changeable rotating cutter having a modified sinusoidal groove of a predetermined width and depth. The rotating cutter is mounted in a die with the modified sinusoidal groove largely enclosed within the die. The modified sinusoidal grooved cutter picks up the material to be cut, carrying it upward into the die opening and there the material is sheared. Flat material can be cut in any direction and the direction of the material being fed into the cutter can be changed at any time.
