Method and apparatus for the production of a cylindrical embossing sheet

摘要

The initial panel is curved around a cylindrical aid with a diameter close to that of the clamping cylinder. Panel construction and dimensioning assures that the longitudinal edges butt together flush, when laid around the aid. The panel is fixed in this position and its longitudinal edges are welded together leaving no gap. An Independent claim is included for equipment carrying out forming and edge-fixing.
