Description

  The present invention relates to an epidermis sticking apparatus for sticking an epidermis to a substrate surface so that a stitching line is at a fixed position.

  2. Description of the Related Art Conventionally, as an automobile interior part, there is a skin-attached product in which a skin is attached to the surface of a base material. For example, a meter hood (portion that surrounds a speedometer, etc.) of an instrument panel, an opening / closing lid of a glove box, a pillar garnish, and the like include those having a skin adhered to the surface of a synthetic resin substrate.

  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 stuck on the surface of the base material, there is a problem that the suture line is easily waved or distorted, and it is difficult to make the position of the suture line constant. Especially when the skin is made of woven fabric or the like, when the skin is manually applied to the base material, the skin tends to stretch partially, which makes the stitching line wavy or distorted, and makes the stitching line constant. Difficult to position. 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.
