Claims14
A rotary shear circular disc having a side, a plurality of projecting segments disposed about the periphery of the disc, each of said segments having a peripheral land and a peripheral groove, the groove being disposed between the land and the side and intersecting the side to form a peripheral cutting edge therewith.
A device suitable for cutting tire cord fabrics comprising a bed knife, a rotatable shear wheel mounted for rotation about an axis and adjacent the bed knife, the shear wheel comprising a circular disc having a side, a plurality of projecting segments disposed about the periphery of the disc, each of said segments having a peripheral land and a peripheral groove, the groove and the side intersecting to form a peripheral cutting edge, the shear wheel and the bed knife mounted so that the cutting edges pass said bed knife when the wheel is rotated.
