ABSTRACT:
An ergonomically-designed racquet stringing machine. The stringing machine includes an electronic control unit coupled to a platform and/or to a height adjustment assembly. The control unit is capable of generating a control signal to automatically adjust at least one parameter of the machine, such as machine height, angle of stringing platform, or string tension, based upon a selected user profile. A method of controlling tension in a racquet while stringing the racquet entails the use of the stringing machine.
