Abstract
The incomplete compound die cut along the circumference of the precision blanking is performed with a specially shaped cutting edge of cutting punch () and/or the die plate () in such a way that the precision blanking () remains initially connected by a material bonding to at leas one partial connecting part on the material strip (), either on the upper or lower plane at a level relative to the material strip. It is then moved together with the material strip in the running direction of the strip to a subsequent removal stage (ejector), in which the precision blanking and the material strip are separated from each other perpendicular to the running direction of the material strip towards the bottom by breaking out the connecting part without a vertical shear force component and without being pressed back, wherein the removed precision blanking () is discharged through a discharge chute () in the die plate.
