GAME BALL

摘要

The present disclosure relates to a game ball and methods for stitching a thread with a high coefficient of friction upon a stripe member present on the game ball. At least one stitching is thus formed upon the stripe member. The stitching formed from the thread enhances the grip and/or spin characteristics of the resulting game ball, improving handling and playability.

主权项

1. A game ball, comprising:
an inflatable bladder; and a cover layer surrounding the bladder, the cover layer being formed from a plurality of cover panels; wherein at least one of the cover panels includes (i) a first stripe member attached to an outer surface of the cover panel and having a texture different from a texture of the outer surface of the cover panel, the first stripe member having a first stripe edge and a second stripe edge adjacent the outer surface, and (ii) at least one stitching upon the first stripe member formed using a thread, the stitching having a static coefficient of friction greater than either the static coefficient of friction of the outer surface of the cover panel or the static coefficient of friction of the first stripe member, when measured according to ASTM D1894 using the pebbled side of a Pattern 62 glass as the test surface.
