ABSTRACT:
Apparatus for affixing surface enlarging, transversally corrugated metal strips to elongate metal basic profiles which are advanced in the direction of their longitudinal axes whilst simultaneously being joined by a joining compound to the wave crests on one side of the corrugated metal strips. The apparatus provides a furnace for heating the basic profile to a temperature which exceeds the melting point of the joining compound, a device for 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 to material. The strip material with solidified joining compound on the crests of the corrugations is advanced in side-by-side relationship with a heated basic profile, the basic profile being brought 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.
