Abstract
In a process for production of a lid ring () which can be connected to the can body, which borders a discharge opening () and has a heat-sealable coating () on which to form a can lid () a closing membrane () can be heat-sealed covering the discharge opening (), a metal strip () with parallel side edges () is formed into a tube () and the side edges () are welded or glued parallel to the tube longitudinal axis (x). The tube () produced in this way is divided into tube sections () of equal length with cut edges () lying in parallel planes. The tube sections () are formed into lid rings () where a first cut edge () is formed into an outer rim () for connection to a can body and the second cut edge () is curled away from the side intended for the heat-sealable coating (). The heat-sealable coating () is applied to the finished molded lid ring.
