摘要: A damper is assembled from a formed frame material having a flange provided with hook-shaped hinge portions formed from the flange and arranged so that when the frame material is folded into the shape of a frame, the hinge portions will be on oppositely positioned sides; and a plurality of blades having complementally configured hook-shaped portions for engagement therewith, by inserting one end of each blade into one complementally configured hook-shaped portion on the flange at one side of the damper frame prior to folding, and then folding the damper frame material about the blades so that the hookshaped portions on the other side of the damper frame engage the other ends of the blades.
