Abstract
A layer of metal is cast on a surface of a metal backing and while the cast metal is still molten, a varying electromagnetic force is generated along an edge of the strip which induces electric currents in the molten metal. The resulting mechanical force exerted in the molten metal is such that the metal is restrained from flowing to the edge of the strip.

A method of manufacturing a laminated metal strip comprising casting on a metal backing strip a layer of molten further metal and while the further metal is still molten causing alternating currents to flow in both the metal backing and the molten further metal such that the phase of the alternating currents changes progressively from at least one edge of the metal backing strip so as to produce a travelling magnetic field that restrains flow of molten metal adjacent the said edge of the strip by interaction between the induced currents and the said moving magnetic field.
