PROBLEM TO BE SOLVED: To prevent the occurrence of coating failure caused by a spit by reducing adherence of fine powder on base portions at both ends of a slit of a nozzle 1 for powder coating having a slit-shaped discharge port 2. SOLUTION: Recessed grooves 6 are provided on outside faces of the base portions at both ends of the slit-shaped discharge port 2. By the air sucking phenomenon by the recessed grooves 6, adhesion of fine powder to the base portions at both ends of the discharge port 2 is reduced. COPYRIGHT: (C)2012,JPO&INPIT |
