Discontinuous metal strip rolling process, for producing strip blank material for stamping coinage and medal proofs and pen nibs, comprises rolling, reversing and re-rolling of a strip section shorter than the roll circumference

摘要

Discontinuous multi-step metal strip rolling comprises rolling, reversing and re-rolling of a strip section shorter than the roll circumference. A metal strip rolling process comprises discontinuously rolling successive sections of the strip (16) between the same two rolls (11,12), the strip being reversed after rolling one such section, of length shorter than the roll circumference, for re-rolling of the section. Independent claims are also included for: (i) use of a reversing mill stand for producing profiled metal strip by the above process; and (ii) use of a reversing mill stand for producing high surface quality metal strip by the above process.
