Title:

MULTILAYER SHEET, WINDING OF MULTILAYER SHEET, AND METHOD FOR PRODUCING THEM

Document Type and Number:

WIPO Patent Application WO/2006/087921

Kind Code:

A1

Abstract:

A long stripping sheet (2A), an adhesive layer (3A), and a base material (4A) are laid in layers to produce a multilayer body, the base material (4A) and the adhesive layer (3A) are cut (half cut) not to penetrate the stripping sheet (2A), and then the base material (4A) and the adhesive layer (3A) are divided into a cover sheet portion (51A), a pillar portion (52A) and the remainder (53A). After the remainder (53A) is stripped and removed, an outer end portion of the pillar portion (52A) is half cut not to penetrate the stripping sheet (2A) thus forming a rising portion (6A). Such a multilayer sheet can be produced at a low cost and formation of a defect in the adhesive sheet can be prevented when a winding of the multilayer sheet is formed.
