ABSTRACT:
Method and apparatus for manufacturing heat exchanger elements in which metal tubing and metal strip are advanced toward each other to a weld station where they are welded together and the tubing-strip combination are then advanced through a first tube straightener, pulling apparatus, a strip corrugator and second tube straightener. The tubing is also passed through tube straightening and shaping apparatus in advance of the weld point. If the combination is collected after leaving the second straightener, the apparatus which is downstream of the weld point other than the pulling apparatus, is inoperative during the advance of the combination therethrough but the combination is then advanced in the reverse direction through such apparatus which is then operative and cut-off apparatus intermediate the weld point and the first straightener cut the combination into panel element lengths which are transferred to further processing apparatus. Alternatively, all the apparatus is operative during the first advance of the combination and the combination is cut into panel element lengths after leaving the second straightener, the elements being transferred to the processing apparatus. If corrugation of the strip is not required, the corrugator is not used in either embodiment.
