Abstract
A frame for a game racquet such as a tennis racquet is formed by interspersed winding of filament material over an elongated mandrel to form a tube. The tube is formed from a wound laminate in which some or all of the circuits of the wind patterns are sequenced in an arbitrary manner by the designer. Each circuit is helically wound along a rotating mandrel. The formed tube is placed in a mold having the shape of the frame, auxiliary pieces for handle and yoke sections are added, and together molded to form the frame.
