Abstract

The method produces drum-type vessels, open at one end of round of polygonal cross-section and of cardboard or corrugated paper. A flat piece of cardboard etc of length corresponding to the vessel circumference is glued along one or both side edges and wrapped round a mandrel and glued together to form a peripheral seam' a pre-shaped base being then inserted in the sleeve so formed and sealed to it. In a number of successive operations the mouth edge is beaded over, while supported on the inside and outside, the first operation turning the edge through 90 deg.' the second for a further 90 deg., and the third rolling it into the final position.
