PCT No. PCT/SE79/00252 Sec. 371 Date Aug. 19, 1980 Sec. 102(e) Date Aug. 15, 1980 PCT Filed Dec. 17, 1979 PCT Pub. No. WO80/01259 PCT Pub. Date Jun. 26, 1980.An apparatus for dividing strip material, in particular strip-shaped scrap resulting from edge-trimming of rolled strip and metal sheet, comprises at least one pair of mutually co-operating cutters (18, 18a), between which the strip material (14) is fed and which are arranged to penetrate the strip material from mutually opposite sides. The two cutters in each co-operating pair are mutually substantially parallel at the moment of their penetration into the strip material. The one cutter (18) in each pair is arranged to engage the strip material slightly in front of the second cutter (18a), as seen in the direction of movement of the strip material, and then to move away from the second cutter in the direction of movement of the strip material, such that the part of strip material located in front of the cutters is separated from the remainder of the strip material by a combined cutting and tearing operation.
