Abstract

The metal sheet is fed through bending rolls into a gap between two cylindrical jackets. The two jackets do not form complete cylinders but are located adjacent to a rail with a Z cross-section. On passing through the cylindrical gap, the front edge of the sheet metal enters the groove on the left-hand side of the Z-rail and the back edge of the sheet enters the groove on the right-hand side of the Z-rail, i.e. the front edge of the sheet is then directly above the back edge and they are only sepd. by the diagonal of the Z-rail. A cylinder and piston rod is used to push the bent sheet through a pair of welding rolls, which are followed by two squeeze-rolls, i.e. to smooth the seam. In this way the cylindrical section of a container is made.
