Abstract: An apparatus for lacing the lateral strings in a racket frame which has already been strung with the longitudinal strings. The apparatus consists of a lower beam provided in its upper surface with two staggered longitudinal rows of vertical slots, the spacing of the slots of each row corresponding to twice the pitch distance of the longitudinal strings of the racket frame. The corresponding slots of the two rows form pairs of slots and the upper surface of the lower beam forms string support surfaces between the pairs of slots. An upper gripper beam is vertically movable with respect to the lower beam. The gripper beam has downwardly facing string surfaces arranged in pairs associated with the pairs of slots of the lower beam. The gripping surfaces of each pair are separated by a downwardly extending lug portion.
