GOLF CLUB HEAD AND METHOD FOR MANUFACTURING THE SAME
First Claim
1. A method for manufacturing a golf club head having a hollow structure composed of a main body-member and a metal face member welded to the main body-member, the metal face member integrally including a face-plate and a turnback, the face-plate forming at least part of a club face, and the turnback extending backward from at least part of the edge of the club face, the method comprising:
- step (a) of preparing a rolled material having a constant thickness;
step (b) of cutting out a face member part from the rolled material;
step (c) of making the face member by forming the turnback through press working on the face member part; and
step (d) of reducing the thickness of a corresponding-to-turnback region by machining prior to the step (c), wherein the corresponding-to-turnback region is a region of the cutout face member part corresponding to the turnback, or a region of the rolled material corresponding to the turnback.

Abstract
A method for manufacturing a golf club head having a hollow structure composed of a main body-member and a metal face member welded thereto, comprises the steps of: (a) preparing a rolled material having a constant thickness; (b) cutting out a face member part or blank from the rolled material; (c) making the face member by forming the turnback through press working on the face member part; and (d) reducing the thickness of a corresponding-to-turnback region by machining prior to the step (c), wherein the corresponding-to-turnback region is a region of the cutout face member part corresponding to the turnback, or a region of the rolled material corresponding to the turnback.

7. A golf club head having a hollow structure composed of
a main body-member provided with a front opening, and a face member closing the front opening, the face member integrally including a face-plate forming a club face for striking a ball and a turnback formed around the face plate, the turnback extending backward from the edge of the club face and having a rear edge of the turnback welded to the main body-member, the face-plate comprising a central thick part and a thinner peripheral part therearound, wherein the thickness of the face member is gradually decreased from the central thick part to the turnback.
