In a method for the finishing of a crankshaft bearing bore in a cylinder crankcase of an internal combustion engine, starting from a prepared crankshaft bearing bore, a finished crankshaft bearing bore is produced with a prescribable desired size, a prescribable desired structure of the bore inner surface and a prescribable desired position of the bore axis. The prepared crankshaft bearing bore is first finished with at least one finishing tool with a geometrically defined cutting edge and then the honing of the crankshaft bearing bore is carried out. In a final finishing operation with a geometrically defined cutting edge immediately preceding the honing, an allowance of at least 0.4 mm is removed, and the honing tool is introduced into the bore coaxially in relation to the desired position of the bore axis and moved within the bore, an allowance of at least 0.08 mm being removed during the honing.

A packaging machine for the packaging of materials to be disposed comprises a container for receiving an open bag as well as evacuation means and a lid which can be opened and hermetically seals the container from the exterior. In order to avoid a contamination of the lid at the inner side thereof, the bag has a collar and a seam connected thereto. The latter is hooked in supporting bolts of the lid.
