Arrangement for rackets for ball games including a frame (8) having a handle and a plurality of mutually crosswise laid strings (5 and 6) which are secured in the frame. Tubular, flexible units (1, 2, 3 and 4) surround certain chosen ones of the strings and extend in their longitudinal direction. Each unit exhibits an internal longitudinal channel having a transverse dimension which generally corresponds to the outer diameter of the strings and an enclosing surface against which crossing strings lie. Because of the characteristic of the enclosing surface these are held in position in such a way that motion of the strings at their intersection points relative to crossing strings is counteracted. |
