摘要:
Disclosed herein is a takraw ball comprising hoops woven into a spherical basket, each hoop being formed of an elongate, generally flat strip of plastics material, each strip having one convex side edge of constant radius and the other side edge of sinusoidal undulating profile and being joined by its ends to form a frustoconical hoop; pairs of hoops being arranged with the strip convex side edges opposed in a common plane or in parallel planes and the sinusoidal side edges relatively staggered so that interwoven hoops intersect at the troughs of sinusoidal side edges.
