Title:
ANNULAR ADHESIVE SHEET FORMING DEVICE AND ANNULAR ADHESIVE SHEET FORMING METHOD
Document Type and Number:
Japanese Patent JP2023096520
Kind Code:
A
Abstract:
To provide an annular adhesive sheet forming device which prevents resources from being wasted as much as possible, and an annular adhesive sheet forming method.SOLUTION: In an annular adhesive sheet forming device EA, a sheet holding member 32 comprises: a first sheet holding surface 32A which is abutted to the side of one side end AS3 of an adhesive sheet AS in an extension direction SD and holds the adhesive sheet AS; and a second sheet holding surface 32B which is directly or indirectly continued to the first sheet holding surface 32A. Energy application means 40 is provided so as to make deformable by predetermined energy, and applies the predetermined energy to the adhesive sheet AS. Thus, the side of another side end AS4 of the adhesive sheet AS in the extension direction SD is bent so as to be closer to the second sheet holding surface 32B, thereby forming an annular adhesive sheet ASL comprising an adhesive surface AS5 which can be bonded to an adhered surface WK1 of an adhered body WK.SELECTED DRAWING: Figure 1
