らなる座席用パッド材の製造方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing a seat padding material, and more specifically, a molded palm formed by press-molding a palm, and a surface of the molded palm. The present invention relates to a method of manufacturing a seat pad material comprising a foam layer laminated on the side.

パッド材１を形成していた。BACKGROUND ART Conventionally, it is known that a palm is press-molded to make a seat pad material. Further, in order to make the surface of the molded palm soft, as shown in FIG. 6, a pad material 1 was formed by bonding a foam 3 to the surface side of the molded palm 2 with an adhesive 4 or the like.

。また成形パ−ム２だけでパッド材１を形成した場合に
は表面に凹凸形状を出すのが困難なものであった。However, on the surface of the molded palm 2, the ends of the palm fibers protrude irregularly, and the bonding surface with the foam 3 is not smooth. The adhesive penetrated into the inside of the molded palm 2, necessitating the use of a large amount of adhesive 4, and was extremely uneconomical. Further, when the pad material 1 is formed from only the molded palm 2, it is difficult to create an uneven shape on the surface.

To provide a method for producing a seat pad material that does not require the use of a large amount of adhesive to bond a molded palm and a foam, and allows for strong bonding.

る。The present invention has been made in view of the above-mentioned problems, and provides a method for manufacturing a seat pad material comprising a molded palm formed by press-molding a palm, and a foam layered on the surface side of the molded palm. , the molded palm is press-molded using a press-molding mold smaller than the surface shape of the pad material to be molded, and at the time of the press-molding, a foamed synthetic resin sheet is inserted in advance into the press-molding mold. The molded palm, the surface of which is covered with the foamed synthetic resin sheet, is placed in a foaming mold that is larger than the molded palm and has the outer shape of the pad material to be molded, and is placed in the foaming mold. The method is characterized in that a stock solution of a foamed synthetic resin is injected and a foam is integrally foam-molded on the surface side of a molded palm whose surface is covered with the foamed synthetic resin sheet.

に凹凸形状を筒易に形成することができるものである。According to the present invention, when molding a palm, a foamed synthetic resin sheet is inserted into a press mold in advance, the foamed synthetic resin sheet is press-molded integrally with the palm, and the surface side of the molded palm is covered with the foamed synthetic resin sheet. As a result, it is possible to form a smooth surface without the risk of palm fiber ends protruding on the surface side of the molded palm, and the molded palm whose surface side is covered with this foamed synthetic resin sheet is placed in a foam mold. When the foamed synthetic resin stock solution is injected into the foamed synthetic resin sheet, the foamed synthetic resin sheet prevents a large amount of the foamed synthetic resin stock solution from impregnating the molded palm, and the foamed synthetic resin stock solution is evenly distributed on the foamed synthetic resin sheet. The foam is impregnated and molded, and the foam and the molded palm can be firmly bonded without using a large amount of adhesive, and an uneven shape can be easily formed on the surface of the foam. It is something that can be done.
