<p>The device for removing cut-out parts from a sheet of material (11) has a supporting plate (12) for the sheets of material (11), in which supporting plate (12) openings (13) with continuous vertical walls (25) are provided. Each cut-out part (10) overhangs the associated opening (13) and rests on the supporting plate (12) with edge supporting surfaces (14). Cutting-out tools (17) made of a steel strip with vertical and horizontal narrow sides (18, 19) are arranged on a tool holding plate (15), which is movable to the supporting plate (12) and away from it, in such a way that they are arranged essentially perpendicular to the assigned cut-out part (10) and symmetrically in relation to the supporting surfaces (14). Each cutting-out tool (17) made of a steel strip has at least one point (20) on the supporting plate side forming the end of one vertical narrow side (18). The angle ( alpha ) between the point (20) and the surface (21) extending from it to the adjacent horizontal narrow side (19) facing the supporting plate (12) projected into the central plane of the narrow side (32) amounts to 20 DEG to 50 DEG . <IMAGE></p> |
