PROBLEM TO BE SOLVED: To provide a manufacturing method for a decorative sheet of a flooring material having a thermoplastic resin backer layer formed by an extrusion machine on a rear surface of a thermoplastic resin decorative sheet, and a non-woven cloth laminated thereon, the manufacturing method not causing an emboss on a front surface of the thermoplastic resin decorative sheet to disappear, and preventing thermal deterioration of the thermoplastic resin backer layer when re-heated.SOLUTION: A manufacturing method for a decorative sheet of a flooring material comprises the following steps for: laminating a thermoplastic resin backer layer on a rear surface of a thermoplastic resin decorative sheet, by extruding from a melting extrusion machine; tucking the thermoplastic resin decorative sheet between an emboss roll and a cooling roll, such that a thermoplastic resin transparent layer on a front surface of the thermoplastic resin decorative sheet is on the emboss roll side, and heat-sealing the thermoplastic resin backer layer on the rear surface of the thermoplastic resin decorative sheet; and at the same time, transferring a form of the emboss roll on the front surface of the thermoplastic resin decorative sheet.SELECTED DRAWING: Figure 1 |
