Title:
METHOD OF ELIMINATING STATIC FROM ELECTRIC INSULATION SHEET, METHOD OF MANUFACTURING ELECTRIC INSULATION SHEET, AND ELECTRIC INSULATION SHEET
Document Type and Number:
Japanese Patent JP2010287579
Kind Code:
A
Abstract:

To provide a method of eliminating static from an electric insulation sheet by easily removing charged areas of positive polarity and negative polarity mingled at a small pitch on one side or both sides of the electric insulation sheet.

At least two sets of ion generation means opposing across a space in which the electric insulation sheet is arranged are used to simultaneously irradiate substantially and mutually reverse unipolar ion clouds on a first surface and a second surface of the sheet at each portion of the sheet, then unipolar ion clouds with the polarities reversed from what was used at the previous irradiation are irradiated on each of the first and second surfaces, thereby eliminating both positive and negative charges from both sides of the electric insulation sheet.
