Abstract (en)
[origin: WO9220410A1] The present invention relates to a system of tensioning for strung sports equipment like tennis racquets with adjustable string tension in which some of the strings are connected to the tensioning mechanism as 'primary string sections' while the rest, as 'secondary string sections', are only indirectly connected to the tensioning mechanism via the primary string sections. The arrangement of the primary and secondary string sections means that a ball striking any part of the surface contacts the same number of primary and secondary string sections.
