The present invention concerns a blade construction for use in longitudinally cutting (in slicing) material webs, such as various paper and cardboard webs, films and recorder tapes, etc., with said cutter a material web being longitudinally parted into partial webs, the cutter consisting of a blade construction comprising one or several blade pairs. On the edge of a first blade, and similarly on the edge of a second blade, has by grinding been produced a micro-rounding, and on the apex of the first blade has been produced a bead. The radius applied in micro-rounding is advantageously within 0.5-5 .mu.m, and the dimension of the bead is advantageously within 0.1-1 mm. |
