Abstract
A method as well as an apparatus manufactures a punch riveted joint, wherein at least two layers are pressed by a holding-down device against the die and a rivet, in particular a semitubular rivet, is provided for joining the layers. The holding-down device is connected by a coupling unit to the punch in such a way that during a punch riveting operation a coupling of the holding-down device to the punch may be varied between a substantially rigid coupling state and an uncoupled state.
