VERFAHREN UND VORRICHTUNG ZUM HERSTELLEN VON METALLVERPACKUNGS-ROHLINGEN

摘要

A process for manufacturing a tubular body, particularly for preserved food cans, comprises the steps of rolling up a metal sheet so as to engage opposite edge portions together, welding the edge portions of the sheet and subjecting the tubular body to radial expansion. The process can either be continuous or may be carried out on sheets each of a length corresponding to a separate tubular body.
