RING-SHAPED COATER AND APPLICATION METHOD BY RING-SHAPED COATER

摘要

PROBLEM TO BE SOLVED: To provide a ring-shaped coating head which applies a coating liquid at high speed and with high precision only to a predetermined part to be coated of an outer peripheral surface of a cylindrical member.;SOLUTION: In a ring-shaped coater, an ejection port formed of a rear lip and a front lip of the ring-shaped coating head is provided at a distance making a prescribed space toward the cylindrical member. At an ejection port part of the the ring-shaped coating head, a diameter from an axial center of a part being in parallel to the cylindrical member at a lip top end of an opposite side to a proceeding direction of the ring-shaped coating head, is larger than a distance from an axial center of a part being in parallel to the cylindrical member of the lip top end of a proceeding direction side of the ring-shaped coating head by over the same diameter. Further an application method using the ring-shaped coater is also provided.;COPYRIGHT: (C)2005,JPO&NCIPI
