BALL FOR BALL GAMES, AND METHOD FOR MANUFACTURING BALL FOR BALL GAMES
First Claim
1. A ball for ball games, comprising:
- a ball body; and
a spherical shell-shaped outer layer having a plurality of leather panels and disposed on an outside of the ball body,wherein the plurality of leather panels each have a main body and an extending portion that is thinner than the main body and extends from a front-side portion of an outer end surface of the main body to configure an outer end surface of the leather panel, the extending portion having a front-side surface joining a front-side surface of the main body,the extending portions of adjacent leather panels are bonded to each other with an adhesive and stitched together with a stitching thread passing through the adhesive, the adhesive being placed between the front-side surfaces of the extending portions and keeping the front-side surfaces of the extending portions from coming into direct contact with each other, and having a top surface to define a dimple space together with the opposite front-side surfaces of the extending portions, anda reinforcing member is provided in the extending portion and is stitched on the extending portion for reinforcing an area of the extending portion stitched with the stitching thread.

Abstract
The ball for ball games has a ball body and a spherical shell-shaped outer layer having a plurality of leather panels and disposed on the outside of the ball body. The plurality of leather panels each have a main body and an extending portion that is thinner than the main body and extends from a front-side portion of an outer end surface of the main body to configure an outer end surface of the leather panel. The extending portions of adjacent leather panels are bonded to each other with an adhesive and stitched together with a stitching thread. In the ball for ball games, the extending portion is provided with a reinforcing member for reinforcing an area thereof stitched with the stitching thread.

8. A method for manufacturing a ball for ball games that has a ball body and a spherical shell-shaped outer layer having a plurality of leather panels and disposed on an outside of the ball body, the method comprising:
-
a leather panel formation step of obtaining each of the leather panels by forming, in a member for leather panel, a main body and an extending portion reinforced with a reinforcing member; an application step of applying an adhesive to an outer surface of each of the extending portions; a joining step of bringing the outer surfaces of the extending portions of two leather panels to which the adhesive is applied into contact with each other; a stitching step of stitching together, with a stitching thread, the extending portions of the leather panels, the outer surfaces of which have come into contact with each other; and an insertion step of inserting the ball body into a spherical shell body that is obtained by repeating the joining step and the stitching step, to obtain a ball. - View Dependent Claims (9, 10, 11, 12, 13)
