Abstract

See full text

A coating method has a reciprocating rotating step. A wire bar is rotated at a first rotational speed for coating a film on a web. In a process of rotating the wire bar at the first rotational speed, a tangential direction of the wire bar at a connecting area between the wire bar and the web is opposite to a moving direction of the web, and then the wire bar is rotated to restore to an original position at a second rotational speed. Meanwhile, the tangential direction is changed and is same to the moving direction of the web. The second rotational speed is far faster than the first rotational speed. A coating device has a base, the wire bar disposed across the base, and a rotation adjusting module connected to the wire bar for driving the wire bar to rotate reciprocatingly.
