METHOD OF FORMING FILM ON CYLINDRICAL BASE MATERIAL SURFACE, AND COVERING LAYER FORMING MACHINE

Title:

METHOD OF FORMING FILM ON CYLINDRICAL BASE MATERIAL SURFACE, AND COVERING LAYER FORMING MACHINE

Document Type and Number:

WIPO Patent Application WO/2002/060599

Kind Code:

A1

Abstract:

A method of forming a film such as a lubricating film on the surface of a cylindrical base material such as a piston, which prevents a wasteful use of lubrication covering coating fluid and keeps a lubricating action, and a covering layer forming machine. When, with a cylindrical base material (A) supported horizontally on a rotation supporting device and kept rotated, a coating fluid (B) supplied from a coating supply unit is supplied to a covering surface (D) to form a film on the surface of the cylindrical base material (A), a coating forming unit (19) with a blade is inclined an inclination angle ($g(u)) of 20 ° - 80 ° with respect to a rotational tangent direction (P) of the base material (A), the blade is kept away from the covering surface (D) as much as the thickness (t) of the covering layer, and the base material (A) is allowed to make at least a 1/4 turn until separation starting at a covering layer (C) to which a coating fluid (B) is supplied is completed fully.
