Abstract

A rotary slitting blade for fabricating expanded metal products includes opposed end surfaces and an outer circumferential surface extending from one of the end surfaces to the other of the end surfaces. A plurality of notches are formed in each of the end surfaces. The notches include curved surfaces having convex curvatures that smoothly transition into one of the end surfaces and/or the outer circumferential surface. The rotary slitting blade improves the quality of a resulting expanded metal product by reducing or eliminating tears, cracks, and fractures in the expanded metal product.
