The plurality of metal strips outputted from the inter-row slit apparatus advance into the cutoff apparatus after entering a downwardly sagging state. The flattened tube fin manufacturing apparatus further includes a control unit controlling a feeding amount of the second feeding apparatus based on a feeding amount of the first feeding apparatus.
