PROBLEM TO BE SOLVED: To precisely control a brake device so as to prevent sudden sliding- down of an accumulated body of a fin for a heat exchanger and to prevent breakage and deformation of the fin for the heat exchanger caused as it is pushed in by a punch. SOLUTION: An accumulation device 29 of a fin for a heat exchanger furnished with a chute 31 where an accumulated body 16 which is made as the fin 10 for the heat exchanger is accumulated moves in a direction of an output port by dead weight of the accumulated body 16 and the fin 10 for the heat exchanger is accumulated in an erected state and taken out from the output port is furnished with a brake device 44 provided in the chute 31 and to regulate movement of the accumulated body 16 in the direction of the output port, sensors 41, 42 provided in the neighbourhood of an input port 25 of the chute 31 and to detect an input port side end part of the accumulated body 16 and a control part 45 to control the brake-device 44 so that the input port side end part of the accumulated body 16 detected by the sensors 41, 42 is positioned at a specified position.
