摘要： A flattened tube fin manufacturing apparatus includes a press apparatus equipped with a mold apparatus forming cutaway portions into which flattened tubes are inserted to produce metal strips; an inter-row slit apparatus cutting the metal strip, in which the cutaway portions have been formed, into predetermined widths to form a plurality of metal strips of a product width arranged in the width direction; and a cutoff apparatus cutting each metal strip of the product width formed by the inter-row slit apparatus into predetermined lengths. The metal strips of the product width outputted from the inter-row slit apparatus advance into the cutoff apparatus after entering a downwardly sagging state. A support portion that contacts and supports lower surfaces of the metal strips of product width in the downwardly sagging state is also provided.

摘要： The present invention aims to provide a manufacturing device for heat exchanger fins that is capable of adjusting for differences between a number of punches and a number of through-holes or cutaway portions in an actual product without causing a metal strip to sag or having punches punch the same positions twice. As a solution, a mold (46) is provided with a plurality of punches (75) and a plurality of dies (76) that form a plurality of through-holes or cutaway portions along a conveying direction of a metal strip (49) and also includes a feeding apparatus (50) that feeds the formed plurality of through-holes or cutaway portions in the feeding direction in a single feeding operation, and a cutoff device (60) that cuts the metal strip (49) into predetermined lengths has an equal number of cutoff punches (68) to a number of the punches and dies disposed along the conveying direction of the metal strip (49), includes a plurality of cutoff punch driving units (72) that respectively and individually operate the cutoff punches (68), and also includes a control unit (80) that controls each of the cutoff punch driving units (72).
