Abstract
A method of producing a roll-shaped body comprises: obtaining an adhesive agent sheet having an embossed shape at both surfaces thereof by imparting an embossed shape on both surfaces of an adhesive agent sheet containing a thermoplastic resin as a main component; overlapping a protective sheet having releasability from the adhesive agent sheet to at least one surface of the adhesive agent sheet having the embossed shape at both surfaces thereof; and obtaining the roll-shaped body by wounding the adhesive agent sheet having the embossed shape at both surfaces thereof and the protective sheet that are overlapped facing one another.
Claims8
A method of producing a roll-shaped body comprising:
- obtaining an adhesive agent sheet having an embossed shape at both surfaces thereof by contacting a melt of an adhesive agent containing a thermoplastic resin as a main component with a surface of a casting roll having an embossed shape at the surface thereof and, after the melt has come into contact with the surface of the casting roll, nipping the melt with the casting roll and a nip roll having an embossed shape at the surface thereof,
- overlapping a protective sheet having releasability from the adhesive agent sheet to at least one surface of the adhesive agent sheet having the embossed shape at both surfaces thereof, and
- obtaining the roll-shaped body by wounding the adhesive agent sheet having the embossed shape at both surfaces thereof and the protective sheet that are overlapped facing one another.
