An apparatus for producing various heat exchangers is disclosed in which a plurality of heat exchangers disposed side by side are formed at once. A series of manufacturing stations for working heat exchanger components such as fins and tubes and for opening the tubes are arranged in an endless manner to thereby automatically carry out the production steps with a high productivity while meeting various requirements of the specifications of the heat exchangers with a high flexibility.

Apparatus for assembling fins and tubes for heat exchangers

A method of stacking fins of heat exchangers suitable for use in producing fins of a plurality of heat exchangers arranged in a group widthwise thereof, characterized by causing one group of fins after another to adhere to a suction plate and forcedly inserting tube receiving apertures formed beforehand in the fins into stacking bars to thereby stack the groups of fins.
