ABSTRACT:
Metal strips or foils more than 800 mm wide are brought to an end temperature of 100.degree.-300.degree. C. by stepwise heating. The strips or foils are deflected at an angle (.alpha.) of 15.degree.-150.degree. C. over 2 to 6 rolls set at increasing temperatures in the direction of throughput, at least the last roll having a double outer layer that can be heated, and the last roll being set at the final, desired temperature. The increases in temperature from one roll to the next lie between 20.degree. and 70.degree. C., preferably between 50.degree. and 60.degree. C. Usefully all the increases are the same. The process according to the invention is employed in the manufacture of composites and in the laminating and lacquering or painting of metal strips or foils.
