Abstract

Procédé de renforcement de cadres d'articles de sport, en particulier de raquettes de tennis, badminton et autres, dans lequel, dans chacune des faces du cadre parallèles au plan de l'article est pratiquée une rainure périphérique continue. Ce procédé est caractérisé en ce que les rainures sont remplies d'un produit de renforcement collé comprenant un cordon de fibres minérales ou organiques noyées dans une résine thermodurcissable, cordon qui est formé de fibres continues que l'on a fait passer dans une filière avec une résine thermodurcissable, l'ensemble ayant ensuite été chauffé pour durcir la résine.
