The separating tool and the counterpressure plate f can be actuated relative to one another by means of at least one actuator in at least one excitation direction with a ramp function and/or with a jump function. Each of these excitation directions lies in a parallel plane to a cutting edge plane of the separating tool. The present invention permits reliable separation of a stamped grid from laminate sections which remain on a carrier film. ## Claims ### Claim 1 A device comprising: a. a separating tool; and b. a counterpressure plate for producing contour geometries in adhesive-containing composite materials wherein the separating tool is adapted to be moved in translational tool stroke directions between an inoperative position and a parting position normal to the counterpressure plate, wherein in the parting position, the separating tool is spaced apart from the counterpressure plate towards the inoperative position, wherein the separating tool comprises a tool cutting edge having a cutting edge plane spanned normal to the tool stroke directions, wherein the device comprises at least one actuator, wherein the separating tool and the counterpressure plate are adapted to be controlled relative to each other by means of the at least one actuator in at least one excitation direction by means of a ramp function and/or a jump function, and wherein the at least one excitation direction lies in a parallel plane to the cutting edge plane of the separating tool. ### Claim 2 (depends on 1) The device according to claim 1, wherein the separating tool has a closed contour and its center axis is parallel to the translational tool stroke directions. ### Claim 3 (depends on 1) The device according to claim 1, wherein the at least one excitation direction is linearly oriented. ### Claim 4 (depends on 1) The device according to claim 1, wherein a stroke of the at least one actuator is smaller than or equal to one millimeter. ### Claim 5 (depends on 1) The device according to claim 1 further comprising two actuators, wherein the two actuators are oriented in a plane parallel to the cutting edge plane and normal to each other. ### Claim 6 (depends on 1) A method for producing contour geometries in adhesive containing composite materials by means of a device according to claim 1, wherein the separating tool is moved in translational tool stroke directions between an inoperative position and a parting position, wherein the separating tool is spaced apart from a counterpressure plate and normal to the counterpressure plate, and moved back, wherein the separating tool parts the composite material having an adhesive-containing substrate layer, and wherein, in the parting position and/or during a return stroke, at least one actuator controls the separating tool and the counterpressure plate relative to each other in parallel to a cutting edge plane by means of a ramp function or a jump function. ### Claim 7 (depends on 6) The method according to claim 6, wherein in the parting position, distance of the separating tool to the counterpressure plate corresponds at least to the thickness of a transport film of the adhesive-containing composite material and is at maximum 100 micrometers larger than the thickness of the transport film.
