Abstract
A coating layer forming apparatus for minimizing the amount of the coating solution when forming a coating layer on a part and enhancing a dimensional precision of a formed surface of the coating layer. The coating layer forming apparatus has a rotation supporting device, a feeder (15), a layer former, and a coating removing device, maintains the inclined angle of a coating former for forming the coating layer at 30 to 70 degrees with respect to a tangential direction of rotation of a coating of a coating surface, and removes excess coating solution deposited on the coating former by a coating removing device.
Claims37
A method of forming a coating layer comprising the steps of:
- making a cylindrical part rotate at a first speed to coat a coating solution on the surface of said cylindrical part,
- making said cylindrical part rotate at a second speed higher than said first speed when positioning a front end of a coating former in a predetermined clearance defining the coating formation thickness with the surface of the cylindrical part at an acute inclined angle between the surface plane of the coating former and a rotational tangential direction at the side of the coming surface of said cylindrical part to make a uniform coating solution deposit on the surface of the cylindrical part, and
- making the cylindrical part rotate at a third speed higher than said second speed when alienating the front end of the coating former from the surface of the cylindrical part and stopping the rotation of said cylindrical part.
A coating layer forming apparatus comprising:
- a rotating support device having supports for detachably attaching centered between them and rotatably holding two ends of a cylindrical part on which a coating layer is to be formed and a rotation drive for making said cylindrical part supported by the supports rotate;
- a coating feeder for coating a coating solution to a surface of the cylindrical part rotating and supported by the rotating support device;
- a layer forming device having a coating former, said coating former being inclined at an acute inclined angel between the surface plane of the coating former and a rotational tangential direction at the side of the coming surface of the cylindrical part, and having a front end directed downward and positioned at a predetermined clearance with the surface of the cylindrical part;
- and
- a coating removing means for removing the coating solution deposited on the coating former of the layer forming device.
The coating layer forming apparatus comprising:
- a rotating support device having supports for detachably attaching centered between them and rotatably holding two ends of a cylindrical part on which a coating layer is to be formed and a rotation drive for making said cylindrical part supported by the supports rotate;
- a coating feeder for coating a coating solution to a surface of the cylindrical part rotating and supported by the rotating support device;
- a layer forming device having a plurality of coating formers provided along the outer circumference of the rotating support device, each coating former being inclined at an acute angle between the surface plane of the coating former and a rotational tangential direction at the side of the coming surface of said cylindrical part, having a front end positioned at a predetermined clearance from the surface of the cylindrical part, and having a position rotated in a reverse direction as the direction of rotation of the cylindrical part along the circumference of said cylindrical part, and
- a washing tank provided beneath said layer former and containing a washing solution for washing a coating deposited on a coating former positioned under it among the plurality of coating formers.
