Abstract

A carrying sleeve, for painting and transfer forms of a metal material, the initial form of which is a rectangular thin-walled flat sheet. The sheet is bent into the desired hollow cylindrical form and the edges of the sheet which point toward one another are permanently connected together. The sleeve surface is processed in order to form a homogeneous continuous outer surface, so that continuous printing can be carried out.
