Abstract
Provided are a composite sheet whose recess-protrusion shape can easily be made crush-resistant in a state that the soft feel against the skin is maintained, and a device and method for manufacturing said composite sheet. A first sheet has a curved part in which one surface thereof rises and the other surface thereof is recessed, and a boundary part adjacent to the curved part. A second sheet is joined to the boundary part of the first sheet so as to cover the other surface of the curved part. A region of the second sheet facing the curved part has a protruding part in which an inside surface on the first sheet side rises so as to approach the curved part and an outside surface on the reverse side thereof is recessed, and a flat part surrounding the periphery of the protruding part.
Claims6
A composite sheet comprising:
- a first sheet, and
- a second sheet joined to the first sheet at a joined part, wherein
- the first sheet includes a curved part in which one surface of the curved part rises and another surface of the curved part is recessed, and a boundary part to surrounding the curved part;
- the joined part joins the second sheet to the boundary part of the first sheet to cause the curved part of the first sheet to be covered by the second sheet so as to form a space in cooperation with the curved part of the first sheet;
- and
- the second sheet includes an opposing region opposing the curved part of the first sheet and a boundary part opposing the boundary part of the first sheet;
- and
- the opposing region of the second sheet includes one protruding region whose inner surface on a side facing the first sheet rises to approach the curved part and whose outer surface on a side opposite to the first sheet is recessed, and only one flat region entirely surrounding a periphery of the one protruding region and disposed inside the boundary part of the second sheet.
