METHOD AND DEVICE FOR CONTROLLING ATTRACTION OF WEB

Japanese Patent JP3856170

B2

PROBLEM TO BE SOLVED: To prevent the peeling or deviation of a slip sheet by changing the voltage or the current of charging so that the optimum attraction necessary for the working can be obtained, and automatically controlling the attraction to eliminate the insufficient attraction.
SOLUTION: When the high voltage is applied to a charging electrode 90, the electron is emitted from an electrode needle 96, a slip sheet web 20 is charged negative to be electrostatically attracted by a metallic web 10. A charging device 34 changes the charging current by the charging current command to be formed by a charging control device, and changes the charging quantity. The charging control device receives the data on the moving speed of the webs 10, 20, the data on the water content of the slip sheet web 20, the data on the relative humidity around the slip sheet web 20, the data on the kind of the photosensitive composition laminarly provided on the metallic web 10, and the data on the kind of the slip sheet web, determines the charging condition suitable for the working from the data table obtained from the operation or the experiment, and gives the command to the charging device 34 in the form of the charging current command.
