Abstract
A cardboard barrel having a tapered configuration, for example, a truncated cone, a truncated pyramid, is obtained from a strip of cardboard 3 having a width corresponding to the height of the barrel to be produced. The strip is seamed and then folded to assume a configuration of stairs protruding in the transverse direction from a longitudinal edge to the other longitudinal edge of the sheet. The sheet so folded is then wound on a creator cylinder 22 having a tapered configuration with steps so that each flat face 3a of sheet 3 is wound on a corresponding face 23 of the creator cylinder 22. <IMAGE>
