MANUFACTURING METHOD AND MANUFACTURING DEVICE OF AIR BUBBLE SHEET

Japanese Patent JP2017213904

A

PROBLEM TO BE SOLVED: To provide a manufacturing method of an air bubble sheet solving problems of temperature control and pressure control generated when conducting lamination of a plurality of films by a compression roll, a nip roll or the like, and problems of sparks when using an electrode needle at the same time.SOLUTION: There is provided a manufacturing method of an air bubble sheet so that a back film 12 is aspirated to a vacuum molding roll 23 by static electricity and adheres to a projection 13 opening side of a cap film 11 by applying DC voltage at high voltage between a wire electrode 25 arranged at a position just before the back film 12 contacts with and fuses to the projection 13 opening side of the cap film 11 and the vacuum molding roll 23 by voltage applying means to let the back film 12 have static electricity.SELECTED DRAWING: Figure 5
