FIELD: mechanical engineering; brake for drag reels. SUBSTANCE: brake band embracing the brake pulley is provided with friction linings secured on it. Air cooling device is located above running-on section of brake band. Square tubes sealed at the ends are secured at ends of friction linings along axis of pulley. Interior of tubes is connected with air duct and with holes in shoes. Holes directed towards running-off end of band are widening towards pulley and those directed towards running-on end of band are narrowing in the direction of pulley. EFFECT: even cooling of pulley. 2 dwg
