ABSTRACT:
A process and device forms a sleeve from a flat, rectangular blank by winding the blank around a mandrel after it has been clamped to the mandrel surface and where the clamp passes under a presser member due to the lifting of the presser member by the action of a cam. The sleeve is permanently formed by a sealing of the blank edges upon the mandrel by a sealing member.
