ABSTRACT:
A device for aiding in the placement of cross strings in a racket head and having a plurality of transversely spaced substantially coplanar string-bearing surfaces adapted for mounting on a first set of alternate longitudinal strings in the racket head and a plurality of pin-like members mounted for rotation on the support about parallel transversely spaced axes substantially perpendicular to the string bearing surfaces thereon and being mounted for axial displacement. Each of the pin-like members has an offset end rotatable to positions parallel and perpendicular to the longitudinal strings and being positioned for engagement with a second set of longitudinal strings intermediate the first-mentioned strings. Means is provided for jointly rotating the members so as to position them for displacement of the longitudinal strings engaged thereby; and means is provided for jointly axially displacing the members to effect relative displacement of the two sets of alternate longitudinal strings thus opening up a clear lateral path between alternate longitudinal strings for receipt and tensioning of a cross string.
