COATER OF ELECTRIC INSULATING SHEET AND METHOD FOR PRODUCING ELECTRIC INSULATING SHEET WITH COATED FILM

摘要

A coater for coating an electric insulating sheet with coating liquid while sustaining an identical charging polarity of the insulating sheet and the coating liquid in a process for coating one surface of a traveling electric insulating sheet with coating liquid, and a method for producing a coated electric insulating sheet. In order to sustain an identical charging polarity of the insulating sheet and the coating liquid, the coater comprises any one or both of a sheet charger for imparting electrostatic charges to one surface of the electric insulating sheet and a coating liquid charger for imparting electrostatic charges to the coating liquid.
