Embodiment Construction

[0018] With reference to FIG. 1, it is noted that the process for making a ball in accordance with the present invention includes the steps of forming a bladder (100), affixing a valve stem on a surface of the bladder (101), inflating the bladder (102), mounting a yarn layer onto the bladder (103), affixing a second layer of rubber on the yarn layer (104) to form a carcass, forming pieces of a cover panel (105), combining the pieces of the cover panel (106) and attaching the combined cover panels onto the carcass (107).

[0019] After the cover panels are securely attached to the carcass, the ball is completed.

[0020] With reference to FIGS. 2, 3, and 4, it is noted that in order to accomplish the goal of reducing material waste, each of cover panels (10) forming a partial outer periphery of a ball is composed of secondary pieces of different shapes and dimensions, i.e. a top piece (10A), a mediate piece (10B) and a bottom piece (10C).

[0021] From this preferred embodiment of the pres...

Abstract

A cover panel structure for making a ball surface includes multiple secondary pieces of different shapes and dimensions to be combined together to form an oval shape.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a ball surface structure, and more particularly to a cover panel structure of a ball surface to reduce waste of material during manufacture of the ball. [0003] 2. Description of Related Art [0004] A conventional ball, as shown in FIGS. 6 and 7, generally comprises a spherical bladder having a carcass (80) which is a hollow rubber ball (not shown) affixed thereto. The carcass has a yarn layer (70) mounted thereon and a plurality of projection ribs (71) integrally protruded and extended on the carcass to define eight leaf shaped recesses surrounded by the ribs (71). Then eight cover panels (60) are securely and respectively attached to a bottom face defining the panel recess to complete the production of the ball. [0005] Before attaching the cover panels (60) to the carcass, the user has to cut the cover panel (60) from a material plate. Because each cover panel (60) has a length subst...
