ABSTRACT:
An apparatus, for forming fins for heat exchangers, comprising a pair of rolls which are provided, on the outer peripheral surfaces thereof, with grooves of a pattern corresponding to the shape of the fins to be formed therebetween and which form them by pressing the fins from opposite sides thereof with the aid of the synchronous rotation of the rolls to give smooth curved outer surfaces thereon, characterized in that the grooves on the rolls are formed so that each groove may be composed of a bottom portion having a substantially arcuate shape and a tapered portion converging from the outer peripheral surface toward the bottom portion of the roll as viewed in section, and at least one roll of the pair of rolls is provided with an urging means for pressing the aforesaid roll against the other roll at a constant pressure. An apparatus for forming needle fins for heat exchangers characterized by providing a means for alternately oppositely bending the fins which have been formed to be possessed of the curved outer surfaces. An apparatus for forming needle fins for heat exchangers characterized by further successively providing an arrangement forming roll area on a downstream side of the fin section forming roll area.
