Zusammenfassung:	PCT No. PCT/DE96/00210 Sec. 371 Date Nov. 7, 1997 Sec. 102(e) Date Nov. 7, 1997 PCT Filed Feb. 5, 1996 PCT Pub. No. WO96/27464 PCT Pub. Date Sep. 12, 1996A mother strip with a metallically pure surface is passed through a melt bath of a metal and whereby the coating is smoothed by rolling immediately after leaving the melt bath. The mother strip, having been preheated, to a temperature clearly above ambient temperature, especially above 200 DEG C., is introduced into the metal bath. The preheating is carried out by indirect heat exchange with the melt bath in an oxygen-free environment. The melt freshly supplied to the melt bath has an increased temperature in accordance with the heat lost due to preheating.
