<p>Automatic press for working strip metal. Comprises a lower mould which carries several secondary moulds, and an upper mould which carries several dies. These cooperate with the moulds in lower mould to give several production stages. A strip of material is fed from one stage to the next while being worked at each stage by the compression of the press. A material feed operates in synchronisation with the latter.</p> |
