Traverse mechanism with rotary wings is a new generation mechanism, which moves the filament back and forth continuously by a pair of blades rotating in opposite direction and conduces to increasing the winding speed further. The internal connections of structure parameters can be determined through the geometrical relations of mechanism parts, the variational regularity of reciprocating velocity of filament can be analyzed in accordance with composition theorem of velocities. Thus, the operation property can be perfected and the reciprocating velocity of filament can be uniformed by regulating the structure parameters, and the requirement of winding the cylinderical package can be satisfied. And the theoretical foundation and implementing means are provided for rational machine design of traverse mechanism with rotary wings.
