Abstract (en)

[origin: DE102007015690B3] The method involves positioning individual metallic layers (10-12) lying one above the other in the range of a processing tool (2'). A special circular punching die (2) with interrupted cutting areas (7) are provided on the layers in defined places of a connecting range (14) in such a manner that the layers are partially cut with the cutting areas of the punching die and are simultaneously reformed together with cut-free areas (4) of the punching die. An independent claim is also included for a punching die for executing a method for establishing a detachable clamp-connection of individual layers of a multi-layer flat gasket. .
