Abstract

A method of producing a conical shell from a metal sheet cut to size. The method includes feeding the sheet in a nip between two transport rollers an incremental distance between respective positions in which nonparallel straight line generatrices on the sheet defining the shell to be produced are in an aligned with the nip, translating a bending roller into engagement with the sheet to incrementally bend the sheet in a direction perpendicular to the generatrix between the nip, then retracting the bending roller away from the sheet, and successively repeating the above steps until the sheet is in the shape of the conical shell to be produced.
