Benefits of technology

[0021] A main object of the present invention is to provide a machine laminated basketball and a manufacturing method thereof, wherein the basketball comprises a round and smoo

Problems solved by technology

Since the channels are integrally protruded on the carcass, such thick channels not only provide no cushion effect but also render the basketball must be hand-made.
It is time consuming and unreasonably increases the manufacturing cost of the basketball.
However, the protruded channel portions are still not cushioned.
Also, it is still difficult to provide the cushion carcass portions with even thickness and uniform cushion effect in the vulcanizing mold.
In other words, the conventional basketball usually cannot achieve uniform cushion effect over the entire spherical ball surface.
This phenomenon is significant in that a non-uniform cushion effect of the conventional basketball affects the overall quality

Example

[0044] Referring to FIG. 1 to FIG. 2 of the drawings, a basketball according to a preferred embodiment of the present invention is illustrated, in which the basketball comprises a channel-less carcass 10, a cushion layer 20 and a skin cover 30.

[0045] The inflatable channel-less carcass 10 has a smooth spherical outer surface 11 and a valve stem 12 formed on the channel-less carcass 10, wherein the channel-less carcass 10 is inflated via the valve stem 12 to support the skin cover 30 to form the basketball. The channel-less carcass 10 can be made by the following steps:

[0046] (i) winding an inflatable rubber ball bladder with reinforcing thread to form a winding thread layer surrounding said rubber ball bladder so as to form an inner carcass;

[0047] (b) covering the inner carcass with an outer rubber layer; and

[0048] (c) heat molding and vulcanizing the inner carcass with the outer rubber layer in a vulcanizing mold to integrally fusion the inner carcass and the outer rubber layer...

Abstract

A machine laminated basketball having a smooth cushion carcass which is capable of providing a uniform and enhanced cushion effect among the entire spherical surface of the basketball. The cushion carcass of the basketball includes a channel-less carcass having a smooth spherical outer surface, a cushion layer attached on the outer surface of the channel-less carcass. The machine laminated basketball further includes a skin cover including a plurality of skin panels and channel elements attached on the cushion carcass, wherein each of the channel elements is positioned between two corresponding edges of the two adjacent skin panels.

Description

BACKGROUND OF THE PRESENT INVENTION [0001] 1. Field of Invention [0002] The present invention relates to a sportsball, and more particularly to a machine laminated basketball which is capable of being mass produced by lamination machine while providing better quality and enhancing an overall cushion effect of the basketball. [0003] 2. Description of Related Arts [0004] A conventional basketball usually comprises an inflatable carcass and a plurality of carcass panels attached thereon, which is made of the following steps. [0005] (a) winding an inflatable rubber ball bladder with reinforcing thread to form a winding thread layer surrounding said rubber ball bladder so as to form an inner carcass; [0006] (b) covering the inner carcass with an outer rubber layer; [0007] (c) heat molding and vulcanizing the inner carcass with the outer rubber layer in a vulcanizing mold to integrally fusion the inner carcass and the outer rubber layer to form an inflatable carcass, wherein a plurality o...
