<p>#CMT# #/CMT# 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. #CMT# : #/CMT# 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. . #CMT#USE : #/CMT# Method for establishing a detachable clamp-connection of individual layers of a multi-layer flat gasket e.g. cylinder-head gasket and flange gasket, for an internal combustion engine. #CMT#ADVANTAGE : #/CMT# The method enables mechanical and detachable connection of the layers in a simple manner without additional materials. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of a flat gasket comprising three metallic layers. 2 : Punching die 2' : Processing tool 4 : Cut-free areas 7 : Cutting areas 10-12 : Metallic layers 14 : Connecting area.</p> |
