A slit forming apparatus consists essentially of a rotary blade assembly, a rotary backing roller, and pressing projections. The rotary blade assembly contacts with or abuts against a strip-shaped travelling over the rotary backing roller and then penetrates said material to form slits in it. The backing roller has banks for holding the strip-shaped material pressed by the rotary blade assembly, and also has grooves for receiving the blades of the rotary blade assembly when they penetrate the strip-shaped material. The pressing projections provided at opposite side ends of the assembly prevent the undersired movement of said material in the lateral or longitudinal direction. With this apparatus, substantially defect-free satisfactory slits are formed in the strip-shaped material.
