Description

  The present invention relates to an apparatus for attaching an epidermis for producing an epidermis-incorporated product in which the epidermis is attached to the surface of a substrate so that the position of a stitching line is constant.

  2. Description of the Related Art Conventionally, automobile interior parts include a skin-attached product in which a skin is attached to the surface of a base material. For example, some instrument panel meter hoods (portions surrounding a speedometer, etc.), glove box lids, pillar garnishes, and the like include a synthetic resin base material bonded to the surface.

  In order to improve the decorativeness, it has been proposed to use a skin obtained by connecting a plurality of skin pieces by stitching and to enhance the decorativeness by a stitching line (stitch). However, when the epidermis is affixed to the surface of the base material, there is a problem that the suturing line is likely to be wavy or distorted, and it is difficult to affix the epidermis to the surface of the base material while keeping the suturing line constant. In particular, when the skin is made of woven fabric or the like, when the skin is manually attached to the base material, the skin is likely to partially extend, thereby making the stitching line wavy or distorted, and a certain stitching line. It was difficult. Moreover, since the stitching line is easy to be noticed and is a part that enhances the decorativeness, if the stitching line is wavy, the decorativeness is impaired and the product value is lost.
