    A rotary slitting cutter is used, for slitting an elongated web of sheet metal into a plurality of strips that are retained in the web during coiling by intermittently spaced connections formed by partially sheared tabs that are easily broken apart for ultimate separation of the strips. For better control of the strength of the tabs despite variations in thickness across the width of the web and to accommodate possible deflection of an arbor carrying the cutter, the cutter is formed with a notch the flanks of which have convex arcuate outer portions 12 and straight inner portions 14 tangential to the outer portions 12. <IMAGE>

    I
    The invention relates to the design of a sheet metal cutting tool.
    Known creams disc cutter with a circular continuous cutting edge.
    The disadvantage of this cutter is the impossibility of using it for cutting sheet metal into strips with preserving, —e, between the strips in the form of brittle ... See | tchek, providing easy winding of the split strips into a single roll not directly on the machine.
    The goal and the zo8} of the shadow is the expansion of the technological capabilities of the mill.
     This goal is achieved by the fact that in a slotted disk cutter with a circular non-direct cutting edge, the cutting edge has at least one radial cavity, the sides of which are made in the form of converging straight lines,: t in an arcuate curve with a circular edge and the base of the depression, moreover, the base of the depression is complete in the form of a concave curve formed by arcuate curves that are conjugated with each other and adjoining lateral sides

    depression or in the form of a straight, perpendicular axis of symmetry of the depression.
    Figure 1 shows a slitting machine with slotted disc cutters designed to cut sheet metal into strips, followed by winding them into a single roll; Figures 2 and 3 are embodiments of a radial depression of the cutting edge.
    The penetration disc milling cutter 1 contains a circular cutting edge 2 having at least one radial depression, the sides of which are made in the form of converging straight 3, joined along arcuate curves 4 and 5, respectively, with a circular cutting edge and the base of the depression 6.
    Slotted disk milling cutters are mounted on the slitter shown in Fig. 1. The sheet metal sheet is removed from the mandrel 7 and, after being cut into strips 8, the matcher is rolled onto the mandrel 9.
    The proposed design of slotted disk milling cutters provides sheet metal cutting into strips while preserving fragile bridges between them.
