ABSTRACT:
Coating apparatus wherein a pretreated sheet metal ribbon passes from a supply coil successively through entry rolls, coating rolls, a curing oven, cooling apparatus, and tension rolls to a recoiler. The ribbon extends through the coating rolls and the curing oven as a long-span catenary. No looping facility is required. The apparatus incorporates novel leading end gripper means and trailing end gripper means for establishing and terminating the catenary in a manner which minimizes the unusable length of ribbon, that is, the uncoated leading end and uncoated trailing end of the processed ribbon. A method of initiating, maintaining, and terminating the catenary is disclosed.
