发明名称 Method of manufacturing a dartboard
摘要 A bundle of skinned, longitudinally torn straws is cut transversely into pieces having predetermined thickness. The pieces are placed into an open topped dartboard contoured frame and compressed from top to bottom and around the periphery. The pieces are then allowed to expand and rearrange in the frame. The surface of the transverse pieces are surface-ground and marked to depict a dart target pattern. Finally, a netting which corresponds to the marked pattern is provided on the ground surface.
