A slitting device including first (31) and second (37) cutting rollers disposed parallel to each other, a first guide roller (33) axially adjacent to the first cutting roller (31), and a second guide roller (35) axially adjacent to the second cutting roller (37). The cutting rollers (31,37) have axially adjacent cutting edges (31b,37b) at which a sheet material is cut into two strips, and recessed portions (31a,37a) on the outer circumferential surfaces. The guide rollers (33,35) have cutout portions (33b,33c,35b,35c) circumferentially extending and axially opposed to each other on the outer circumferential surfaces, and projections (33a,35a) defined by the cutout portions (33b,33c,35b,35c) and opposed to the recessed portions (31a,37a) of the cutting rollers (31,37). The cutting rollers cooperate with the corresponding guide rollers to define therebetween spaces for the strips of the sheet material. The cutting rollers and the guide rollers have a same outer diameter. The invention also relates to an apparatus for forming corrugated-fin strips from a sheet material and to a method for cutting a sheet material into strips.
