ABSTRACT:
A pair of generally parallel snapping rolls are disclosed which mount beneath a stripper plate having a fore and aft extending slot through which stalks of corn may pass. The snapping rolls rotate in opposite directions and serve to draw stalks downwardly until the ears thereof strike the stripper plate and are snapped free. Each snapping roll has longitudinally extending flutes, the flutes of one roll being interleaved with those of the second roll. On each roll, the odd numbered (1, 3, 5, etc.) flutes extend radially outward while the even numbered (2, 4, 6, etc.) flutes extend outward at a non-radial angle. Rotating the two rolls in synchronism thus results in the generation of a cyclic narrow and wide spacing sequence between opposing flutes. This cyclic action provides improved efficiency in the harvesting operation.
