Production of an annular body (10) made from sheet metal comprises forming punch-outs (12) and/or edges (14) from sheet metal strips whose length corresponds to the periphery of the annular body and rolling the metal strips and joining the free ends together to form the annular body. An independent claim is also included for an annular body produced by the above process.
