価にできる。According to the present invention, the end treatment of the skin body can be facilitated by the winding plate that protrudes into the inside of the cavity during molding and is located on the right side of the winding edge that can be retracted to the outside of the cavity during molding. The insert plate can be opened and closed automatically in conjunction with mold closing and mold opening, and there is no need to set the insert plate during molding or remove the insert plate after molding, and the mold structure is simple. It can be done cheaply.
