ABSTRACT:
In a frame (1') for ball game racquets made of plastic the abrasion and cutting of the guts against the edges of passages in the frame is avoided. For that purpose the frame (1') comprises a center strip (3) of thermoplastic resin, the hardness of which is less than or equal to the hardness of the guts. Hollow profiles (4, 5) of duroplastic, fibre-reinforced synthetic resin are moulded onto both sides of the center strip. The passages are drilled into the center strip (3) after the frame has been produced and then the frame is strung.
