发明名称 METHOD AND APPARATUS FOR DETECTING SLIP OF FILM AND FILM-CONVEYING TYPE COATING APPARATUS WHICH IS EQUIPPED WITH THE APPARATUS FOR DETECTING SLIP OF FILM
摘要 <P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for detecting slip of a film occurring on conveying rollers during coating, and a film-coating apparatus which monitors conveying status of the film in a coating step based on the result of slip detection and controls conditions such as tension applied to the film at conveying so as to suppress occurrence of slip and prevent damages caused by the slip. Ž<P>SOLUTION: The method for detecting slip of a film is used in a film-conveying apparatus in which a film with a coating on its surface is conveyed via at least two conveying rollers. In the method, the slip of the film on the conveying rollers is detected based on a change in vibrational waves applied to the film conveyed between the at least two conveying rollers.
