Abstract
An apparatus for applying a powder of anti-sticking agent on a coil of oriented electrical steel strip formed on a coiler comprises a movable assembly moving closer to and away from the coiler, a stationary hood attached to the movable assembly and having slit-like suction ports provided along the walls thereof, one end of the suction ports opening toward the coiler, a duct-collecting duct connected to the slit-like suction ports of the stationary hood, movable hoods provided on the stationary hood to vertically open at the top and bottom of the open end of the stationary hood, and a group of electrostatic powder spray guns directed toward the coiler in the stationary hood in which they are disposed. The movable assembly recedes and the movable hoods open as the diameter of the coil increases so that a given space is always maintained between the surface of the coiled strip and the movable hoods. The slit-like suction ports draw out only such portion of the anti-sticking agent as is about to flow out through the small space left between the coil and hood.
