Abstract:
1. Method for coating lengths of profile bars made of plastic or metallic material in a production line, comprising, without interrupting a progress of the production line: conveying a plurality of profile bars successively and one after another in the production line, coating a face or faces of each of the profile bars with a metal foil, by applying a continuous strip of coating material forming the metal foil on the profile bar, wherein the metal foil has a surface hardness higher than that of said profile bar, causing said foil to adhere to said profile bar at any point of one of the faces of the metal foil, and after adhesion, performing at least one of the following: (i) detecting upstream and downstream ends of two successive profile bars, and at these two ends, upstream and downstream respectively, performing two different cutting operations, taking into consideration the distance between said profile bars, and (ii) detecting upstream and downstream ends of one and the same profile bar, and at these two ends, upstream and downstream, performing two different cutting operations, taking into consideration the distance between said ends and the position of said profile bar.
