Abstract

A method for making a ball includes the steps of preparing a mold composed of a lower mold and an upper mold detachably connected to the lower mold, wherein the lower mold and the upper mold have multiple suction holes, filling the lower mold and the upper mold with covering pieces, filling the lower mold and the upper mold with strips, placing a bladder in the lower mold and on top of the covering pieces and strips in the lower mold, mating the upper mold with the lower mold, securing the covering pieces on the bladder, and removing finished product from the mold.

Claims

1. A method for making a ball comprising the steps of:

a. preparing a mold composed of a lower mold and an upper mold detachably connected to the lower mold, wherein the lower mold and the upper mold have multiple suction holes;

b. filling the lower mold and the upper mold with covering pieces;

c. filling the lower mold and the upper mold with strips;

d. placing a bladder in the lower mold and on top of the covering pieces and strips in the lower mold;

e. mating the upper mold with the lower mold;

f. securing the covering pieces on the bladder; and

g. removing the finished product from the mold.

2. The method as claimed in claim 1, wherein an inner face the lower mold and upper mold is evenly divided into portions each corresponding to one of the covering pieces and a gap is defined between every two adjacent portions to receive therein a corresponding one of the strips.

3. The method as claimed in claim 2, wherein a circular recess is defined in the inner face of the lower mold and the upper mold to receive therein one of the strips.

4. The method as claimed in claim 1, wherein pressure is employed in the step f to secure the covering pieces on the bladder.

5. The method as claimed in claim 2, wherein pressure is employed in the step f to secure the covering pieces on the bladder.

6. The method as claimed in claim 3, wherein pressure is employed in the step f to secure the covering pieces on the bladder.
