A method and apparatus for manufacturing elongate heat-exchanger blanks composed of a basic substrate profile having at least one length of corrugated metal foil strip mechanically bonded thereto. A basic elongate profile string is advanced at a predetermined speed along a fixed path and at least one strip corrugating device is arranged to produce a continuous length of corrugated strip and to feed the strip into the path of the basic profile via a number of corrugated strip cutting and feed means. These latter means operate cyclically to cut the strip at predetermined intervals and to join the cut lengths of strip to the basic profile string in spaced relationship at a frequency corresponding to the intervals. |
