Abstract
A flattened tube fin manufacturing apparatus includes: a press apparatus; an inter-row slit apparatus forming metal strips of a product width that are arranged in the width direction; a first feeding apparatus feeding the metal strips cut by the inter-row slit apparatus downstream; a cutoff apparatus that cuts the metal strips formed by the inter-row slit apparatus into predetermined lengths to form flattened tube fins; and a second feeding apparatus that feeds the flattened tube fins downstream. 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.
