Abstract
A composite ball is formed with wound filament in a winding machine by winding the filament on a core, which can be permanent and form part of the finished ball. Alternatively, the core can be temporary. When winding is completed, the wound body is removed from the winding machine, an exterior of the wound body is finished, and the wound body is cured. When the core is permanent, at least a portion of the core is removed from the winding machine along with the wound body so any excess of the permanent core can be removed. The temporary core, however, is removed from the wound body, and the void is filled with filler material.
Claims26
A method of forming a composite ball with filament in a winding machine, comprising not necessarily in order:
- forming a wound body by winding the filament on a core in the winding machine, the core having at least a core portion to be removed from the wound body;
- removing the wound body from the winding machine;
- curing the wound body;
- and
- finishing an exterior of the wound body by filling a void resulting in the wound body from removal of the core portion from the wound body or removing excess of the core portion left outside the wound body.
A method of forming a composite ball with filament in a winding machine, comprising not necessarily in order:
- forming a wound body by winding the filament on a core in the winding machine, wherein the core comprises a permanent core;
- removing the wound body from the winding machine;
- curing the wound body;
- and
- finishing an exterior of the wound body by removing excess of the permanent core from the exterior of the wound body.
A method of forming a composite ball with filament in a winding machine, comprising not necessarily in order:
- forming a wound body by winding the filament on a core in the winding machine, wherein the core comprises a temporary core;

- and
- finishing an exterior of the wound body by removing the temporary core portion from the wound body and the permanent core portion and filling a remaining void of the wound body with a filler material.
A composite ball formed with filament in a winding machine by a method, comprising not necessarily in order:
- forming a wound body by winding the filament on a core in the winding machine, the core having at least a core portion to be removed from the wound body;
- removing the wound body from the winding machine;
- curing the wound body;
- and
- finishing an exterior of the wound body by filling a void resulting in the wound body from removal of the core portion from the wound body or removing excess of the core portion left outside the wound body.
A method of forming a composite ball with filament in a winding machine, comprising not necessarily in order:
- forming a wound body by winding the filament on a permanent core in the winding machine;
- removing the wound body and at least a portion of the permanent core from the winding machine;
- curing the wound body;
- and
- finishing an exterior of the wound body by at least partially removing excess of the permanent core.
