Abstract

Improvements in the manufacturing process of reinforced synthetic tennis rackets starting from tubular braids woven with filamentary material impregnated with polymerizable synthetic material, inflated internally to be applied to the interior of a mold, characterized by the fact that, for the formation of the frame, at least two elementary structures are prepared that lean one on the other and joined together so that they form one or more reinforcing ribs, said multiple structure itself being surrounded, in all its periphery, by a supplementary structure made starting from a continuous woven braid that ensures its fastening, and due to the fact that said multiple fastened structure follows, between an exit point and an arrival point, a particular course suitable to reinforce said frame at the stress location points.
