Abstract

A face insert for golf club head in one embodiment can comprise a substrate comprising a score line groove-free front surface. A cover layer is provided at least on the front surface of the substrate. The cover layer can alternatively overlay at least a portion of the peripheral edge of the substrate. The cover layer comprises a ball-striking surface spaced by the cover layer from the substrate. Plural elongated score line grooves can extend into the polymer layer from the ball-striking surface. In addition, visible markings are interposed between the cover layer and the front surface of the substrate, the visible markings being visible through the cover layer. In one form the visible markings comprise elongated score line markings and target markings in a central portion of the substrate. The visible markings can be screen-printed markings, which are then protected by the cover layer from wear. The cover layer can be molded and can be a polymer layer. The score line grooves can be formed, for example, by molding during molding of the polymer layer.

Claims

1. A face insert for a wood-type golf club head comprising:

a substrate comprising a front surface and a peripheral edge;

a polymer layer on at least the front surface of the substrate, the polymer layer comprising a ball-striking surface spaced by the polymer layer from the substrate;

plural elongated score line grooves extending into the polymer layer from the ball-striking surface;

visible markings interposed between the polymer layer and the front surface of the substrate, the visible markings being visible through the polymer layer and comprising score line markings interposed between the polymer layer and the front surface of the substrate, the visible markings also comprising target markings interposed between the polymer layer and the front surface of the polymer layer at a central portion of the polymer layer; and

wherein the polymer layer overlays at least both the peripheral edge and the front surface of the substrate.

2. A face insert for a golf club head according to claim 1 wherein the polymer layer and the elongated score line grooves are molded, the polymer layer being a cured polymer layer.

3. A face insert for a golf club head according to claim 1 in combination with a golf club head body, wherein the face insert is attached to the golf club head body.

4. A face insert for a golf club head according to claim 1 wherein the substrate is a composite substrate.

5. A face insert for a golf club head according to claim 1 wherein the target markings are spaced from the score line markings, wherein the substrate comprises first and second side edges and wherein the score line markings and score line grooves extend in directions perpendicular to the side edges.

6. A face insert for a golf club head according to claim 1 wherein the visible markings are screen-printed markings.

7. A face insert for a golf club head according to claim 1, wherein said substrate comprises a heel portion and a toe portion and wherein the elongated score line grooves comprise a first set of plural elongated grooves extending into the polymer layer and positioned at least partially across the ball striking surface of the toe portion of the substrate and a second set of plural elongated grooves extending into the polymer layer and positioned at least partially across the ball striking surface of the heel portion of the substrate;

wherein the score line markings comprise a first set of plural score line markings extending at least partially across the toe portion of the substrate and a second set of plural score line markings extending at least partially across the heel portion of the substrate;

wherein the first set of plural elongated grooves overlies and is substantially aligned with and spaced from the first set of score line markings and wherein the second set of plural elongated grooves overlies and is substantially aligned with and spaced from the second set of score line markings.

8. A face insert for a golf club head according to claim 1, wherein said substrate comprises a crown portion and a sole portion, and wherein said target markings comprise a first set of plural target markings extending at least partially across the crown portion of the substrate and a second set of plural score line markings extending at least partially across the sole portion of the substrate.

9. A face insert according to claim 1 wherein the target markings are positioned in a score line marking free central portion of the polymer layer.

10. A face insert for a golf club head according to claim 1 wherein the substrate comprises a crown portion, a sole portion, a toe portion and a heel portion, the score line markings comprising a plurality of spaced apart elongated score line markings, and wherein score line markings adjacent to the sole portion are shorter than score line markings adjacent to the heel portion.

11. A face insert for a golf club according to claim 1 wherein the substrate comprises a crown portion and a sole portion, and wherein the score line markings below the center of the substrate and closer to the heel portion are shorter than the score line markings above the center of the substrate and closer to the crown portion.

12. A face insert for a golf club according to claim 1 wherein the substrate comprises a crown portion, a sole portion, a heel portion and a toe portion, wherein the score line markings comprise a first set of plural score line markings extending partially across the toe portion of the substrate and a second set of plural score line markings extending partially across the heel portion of the substrate.

13. A face insert for a golf club according to claim 12 wherein the score line markings comprise elongated score line markings, the score line markings of the first set being in alignment with the score line markings of the second set, and wherein the target markings are positioned between the first and second sets of score line markings.

14. A face insert for a golf club according to claim 12 wherein the score line marking of the first set that is nearest to the sole portion is shorter in length than the score line marking of the first set that is nearest to the crown portion;

and wherein the score line marking of the second set that is nearest to the sole portion is shorter in length than the score line marking of the second set that is nearest to the crown portion.

15. A face insert for a golf club according to claim 12 wherein the score line grooves comprise a first set of plural score line grooves extending partially across the toe portion of the substrate and a second set of plural score line grooves extending partially across the heel portion of the substrate.

16. A face insert for a golf club according to claim 15 wherein the first set of plural score line markings comprise markings positioned in alignment with and under the grooves of the first set of plural score line grooves, and wherein the second set of plural score lines comprise markings positioned in alignment with and under the grooves of the second set of plural score line grooves.
