ABSTRACT:
A method of affixing surface enlarging, transversally corrugated metal strips to elongate metal basic profiles which are advanced in the direction of their longitudinal axes while simultaneously being joined by a joining compound to the wave crests on one side of the corrugated metal strips. The method comprises the steps of heating the basic profile to a temperature which exceeds the melting point of the joining compound, advancing the metal strip longitudinally externally of the path of the basic profile while applying the joining compound to the crests and solidifying a suitable portion of the compound at respective crests by conducting heat away from the compound through the strip material, advancing the strip material with solidified joining compound on the crests of the corrugations thereof in side-by-side relationship with a heated basic profile, bringing the basic profile into contact with the coated crests to cause heat from the profile to melt the joining compound, and in conjunction with this latter step conducting heat away from the joining compound through the strip material to solidify the joining compound and to establish a joint between each crest and the basic profile.
