A manufacturing apparatus that manufactures flattened tube fins, in which cutaway portions for inserting flattened tubes for heat exchanging are formed, includes: a press apparatus provided with a mold apparatus that forms the cutaway portions in an unmachined metal thin plate to produce a metal strip; an inter-row slit apparatus cutting the metal strip into predetermined widths to form a plurality of metal strips of a product width; a cutoff apparatus cutting each metal strip of the product width into predetermined lengths; a holding apparatus that holds a plurality of metal strips of the product width that protrude from a downstream side in the conveying direction of the cutoff apparatus; and a stacker apparatus for stacking the flattened tube fins that have been cut into predetermined lengths by the cutoff apparatus.

Manufacturing apparatus for flattened tube fins

A stacking apparatus capable of stacking flattened tube fins efficiently is provided. There is provided a stacking apparatus for stacking flattened tube fins, each having a cutaway portion through which a heat exchanger flattened tube is inserted, formed from one side to the other side in a width direction, the stacking apparatus including a stack pin to be inserted into the cutaway portion, and the stack pin has a swing-preventing structure.
