Estimating the term…
A local connection of contact surfaces of top and bottom sheets is formed in a defined connection zone. The zone is polygonal and the top and bottom sheets jointly form within the periphery of this zone a connecting lip with their first side faces located opposite one another cut obliquely through their sheet thickness. These first side faces of the sheets and their adjacent obliquely-oriented second side faces in the zone are complementarily beveled in the form of a conical wall running downwards and inwards, so that in the vicinity of these second neighboring side faces the underside of the bottom sheet protrudes inwards past the top surface of the connecting lip at the location of the top outside edges of its first side faces. A method and an apparatus are arranged to implement the local connection.

A local connection of a top sheet and a bottom sheet onto one another in their contact surface in at least one defined connection zone, wherein the zone is polygonal and wherein within the periphery of the zone the top and bottom sheets jointly form a connecting lip, first side faces of the top and bottom sheets located opposite one another are cut obliquely through a sheet thickness of the top and bottom sheets, the first side faces of the top and bottom sheets and adjacent obliquely-oriented second side faces of the top and bottom sheets in the zone are complementarily bevelled in the form of a conical wall, so that in the vicinity of the second side faces the underside of the bottom sheet protrudes inwards past the top surface of the connecting lip at the location of the top outside edges of its first side faces.
