Description

  The present invention relates to a method for manufacturing a skin-implanted product in which an epidermis is affixed to a surface of a substrate 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.

Then, as shown in FIG. 13, the end 15a of the outer skin 15 protruding from the lower side of the blade 51 to the front side is pulled manually, etc. until the stepped portion 16a of the connecting portion 16 hits the blade 52 of the blade. The skin 15 is displaced to position the suture line 21a. Further, the blade 15 of the blade is covered with the blade 52 of the blade and the cover body 71 by pressing the skin 15 against the adhesive application surface 13a of the base material 11 not covered with the cover body 71. The epidermis 15 is held between the adhesive-applied surfaces 13a of the base material 11 that is not, and the position of the suture line 21a after the positioning is maintained.

  In the cover body retracting step, the cover body operating lever 75 is pushed rearward away from the operator, and the cover body 71 is moved between the skin 15 and the base material 11 from the surface 15 and the base material 11 as shown in FIG. It is retracted backward and removed from between the skin 15 and the substrate 11. As a result, the skin 15 is laminated on the adhesive-coated surface 13 of the substrate 11 that has been covered with the cover body 71 so far, and the back surface of the skin 15 contacts the adhesive on the adhesive-coated surface 13.

  Thereafter, the blade operating lever 55 is pulled toward the front side, and the blade 51 is moved away from the substrate mounting table 41 and the blade 52 of the blade is separated from the surface of the skin 15 as shown in FIG. Then, as shown in FIG. 16, the base material 11 and the skin 15 are removed from the base material mounting table 41, the end portion of the base material 11 is rolled up at the end 15 a of the skin 15, and the end 15 a of the skin 15 is It is bonded and fixed to the back surface of the end portion of the substrate 11 with an adhesive 12a. In this way, a product with an attached skin is obtained.

  In some cases, depending on the product to which the skin is applied, it is not necessary to wind up the end of the base material at the end of the skin. Moreover, in the said Example, although the cover body and the braid | blade were enabled to move by rocking | fluctuation, you may advance and retreat by a slide. The position of the suture line after the positioning may be maintained by another method, for example, by gripping the edge of the epidermis with the gripping means after the suture line is positioned. Furthermore, the adhesive application surface 13a not covered with the cover body in the above embodiment is covered with another cover body arranged between the skin and the base material, and the blade is located near the stepped portion of the skin positioned on the cover body. After the cover body 71 shown in the embodiment is retracted from between the base material and the skin, the blade of the blade is separated from the skin, and another cover body is attached.
