Abstract: AT LEAST TWO SETS OF ION-GENERATING MEANS (8U) ARE PROVIDED TO FACE EACH OTHER THROUGH A SPACE HAVING AN INSULATING SHEET (S). THE FIRST AND SECOND SURFACES (100, 200) OF THE SHEET (S) ARE SIMULTANEOUSLY IRRADIATED WITH MONOPOLAR ION CLOUDS SUBSTANTIALLY OPPOSITE TO EACH OTHER IN POLARITY GENERATED FROM THE ION-GENERATING MEANS (5D, 5F). THE SHEET (S) IS SUBSEQUENTLY IRRADIATED WITH MONOPOLAR ION CLOUDS REVERSE IN POLARITY TO THAT OF THE PREVIOUSLY APPLIED ION CLOUDS, TO ELIMINATE THE POSITIVE AND NEGATIVE CHARGES (101, 102, 201, 202) OF BOTH THE SURFACES (100, 200) OF THE INSULATING SHEET (S).

Abstract: The present invention provides a film roll comprising an electrified portion at at least part in the transverse direction of a film that is wound into a roll, in which the difference between the maximum width and the minimum width of the electrified portion is 10 mm or less. In this manner, side slipping can be reliably prevented while securing escapeways for air at the edges, and a film roll having no side slips, wrinkles, deformation, decentering, or the like can be manufactured. The film roll of the present invention can be manufactured by intermittently electrifying the film at a predetermined cycle, the ratio of the time duration of the electrification in the cycle being 10 to 80%. The film roll of the present invention has a high adhesive force and does not suffer from slipping during evacuation in a vacuum evaporator. Thus, the film roll is suitable as a master roll for metallization and can be suitably applied to various uses such as magnetic tapes, packaging materials, capacitors, and the like.

Abstract: A film roll body capable of simultaneously realizing the strong prevention of displacement and air vent from an end part and eliminating a displacement, a warpage, a deformation, and a misalignment of end faces by providing a charging treated part having a maximum width-to-minimum width difference of within 10 mm at least on a lateral part of a film wound in a roll shape; a method of manufacturing a film roll body, comprising the step of applying a charging treatment to a film intermittently at specified intervals, wherein the ratio of the time for charging treatment is set at 10 to 80% within one cycle; whereby, because the film roll body has a strong adhesiveness and is not deviated at the time of evacuation by an evaporator, the film roll body is particularly excellent for use as an original roll for evaporation and can be used suitably for a wide range of applications such as magnetic tape, packing materials, and capacitors.

Abstract: PROBLEM TO BE SOLVED: To provide a method in which a dust attraction caused by an electrostatic force and a coating unevenness of a solvent and a removal of a metal vapor-deposition film at a post-processing are not generated in the method for manufacturing an insulative sheet roll body by winding an insulative sheet such as a film or the like on a winding core in the form of roll while imparting a surface pressure thereto by pressing it by a contact pressure roll. SOLUTION: A friction charging of a contact pressure roll and an insulative sheet is inhibited by forming an electric field between the contact pressure roll and a winding core. A direction of the electric field formed is determined by a polarity of the friction charging of the insulative sheet at the friction charging with the contact pressure roll.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a base material having a thin film, in which sparkelike discharge caused in a reeling-out part or a reeling part of the rolled base material is inhibited by simple constitution and damage to the base material, deterioration of film quality and trouble of an installation are difficult to be caused. SOLUTION: Gas is supplied to a reeling-out part and/or a reeling part of the rolled base material and the feed rate of gas is controlled so that pressure (P) in the blowing part of the gas is controlled so that pressure (P) in the blowing part of the gas becomes 1

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for eliminating static charge, by which problems of static charge in subsequent steps can be prevented by independently eliminating charged patterns existing on the front and back surfaces of an insulating sheet such as a film, and an insulating sheet. SOLUTION: One surface of an insulating sheet is subjected to charging treatment so as to make the charged polarity of said one surface become even, and charge neutralizing treatment is conducted on the said one surface to eliminate the charged pattern on the treated surface.
