Title:
ELASTIC COMPOSITE SHEET MANUFACTURING METHOD AND MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/150801
Kind Code:
A1
Abstract:
A manufacturing method and manufacturing device of an elastic composite sheet are provided which enable easily manufacturing an elastic composite sheet having desired characteristics. An elastic resin material having a thermoplastic elastic resin as the main component is heated and melted, and the elastic resin material is discharged in a film or a linear shape from a discharge mechanism (20) to form a film-shape or a linear-shape intermediate product (2). At a temperature above than the temperature region at which the elastic resin material elastically deforms, stretching is performed until the thickness or width of the film-shape intermediate product (2) or the thickness of the linear-shape intermediate product (2) assumes a prescribed value; with a cooling roller (3), the intermediate product (2) is cooled to the temperature region at which the elastic resin material elastically deforms, and the intermediate product is hardened, forming a film-shape or linear-shape elastic member (3). The elastic member (3) is stretched with a stretch roller (40) to a prescribed stretching ratio, and the stretched elastic member (3) is laminated on and bonded to a first base material sheet (4). Preferably, the elastic member (3) is laminated between the first and a second base material sheet (4, 6).
