Abstract
For an opening for a container wall, a rivet-shaped protective covering is made and applied by an apparatus. A sheet-like piece of foil is laid down by all applying device on a first wall area bordering the opening. The section overlapping the opening is formed into the opening by a first forming device. A part of the section projects out of the opening at a second wall area bordering the opening. The part of the foil piece projecting out of the opening is formed against the second wall area by a second forming device, whereby the rivet-shaped form of the foil piece is maintained. The rivet-shaped protective covering is affixed permanently to the container wall by an affixing device.
