Abstract (en)
[origin: EP0503166A1] Apparatus for plotting, cutting and/or punching the contour of figures on and into respectively, sheet material 4, provided with a traction- and/or friction feed for moving the sheet material to and fro in accordance with a first component of a plotting, cutting or punching direction, a tool head 1 movable in a direction perpendicular to the direction of said traction and/or friction feed and parallel to the surface to be cut in accordance with a second component of said plotting, cutting or punching direction, said tool head being provided with a housing 7 which can be moved in a direction at perpendicular to the surface of said sheet material and a servo-controlled motor controlling the position of a bush rotatably arranged in said housing provided with either a plotting, cutting or punching tool, means for moving the housing towards the sheet material to be plotted, cut or punched and means for positioning the cutting or punching tool such that the cutting or punching direction coincides with the tangent of the contour to be cut, two rollers 18 being arranged at the side of the bush facing the sheet material and slightly extending therefrom to roll over said sheet material during cutting and punching respectively, said cutting or punching tool being arranged between said two rollers, its cutting direction equalling the rolling direction of said rollers and extending therefrom over a distance corresponding to the desired cutting or punching depth, the tool top being situated on the axis of rotation of the bush. <IMAGE>
