发明名称 Method for stringing a racquet
摘要 A method for stringing a racquet characterized by forming a linearly expansible pre-strung web having a plurality of rows of diamond shaped interstices and then stretching said web row-by-row along a linear axis of expansion by starting with the innermost rows of the web and proceeding symmetrically outwardly to the outermost rows of said web. As a final step, the linearly expanded web is laced to the head of a racquet. An apparatus for accomplishing the above method is characterized by an elongated base supporting a pair of carriages for reciprocal, colinear movement. A plurality of stretcher bars are supported by the base between the carriages to stretch the web row-by-row away from a central axis. Links are provided to selectively couple the stretcher bars to the carriages.
