1. Cutting machine blade (1) to be fitted into a cutting tool of a cutting machine, built and specifically intended for cutting a multiwalled composite plate (20)—particularly a sandwich plate—made of cardboard or paperboard material or plastic, which has at least an upper wall and separated therefrom a lower wall (21, 22), which are respectively relatively thick and difficult to cut, and an intermediate layer (23) lying between them, which is relatively easy to cut, particularly in the form of a structure between five and 60 millimeters high made of material with cavities, in particular formed as a repeating cell pattern structure or from foam,
wherein the cutting machine blade (1) is intended for use in the scope of an automatic cutting mode, in which the cutting machine blade (1) is guided by the cutting machine in a feed direction (52) along the composite plate (20), having a holding section (15) for fitting the cutting machine blade (1) into a blade holder of the cutting tool, and a cutter (10) with an edge, a first zone (12) of the edge (16) extending obliquely relative to the feed direction (52) being provided for cutting the lower wall (22), and a second zone (11) of the edge (16) extending obliquely relative to the feed direction (52) being provided for cutting the upper wall (21), respective profiles of the edge (16) in the region of the first and second zones (12, 11) respectively making a first angle (41, 42) of between about 30° and about 70° with the feed direction (52), characterized in that there is an intermediate zone (13) of the edge (16) between the first and second zones (12, 11), with a profile that makes a second angle (50) with the feed direction (52) which is greater than the first angle (41, 42), in particular greater than 90°. |
