Kinematic design method for six-bar linkage sley drive mechanisms in weaving

A kinematic design method has been developed for calculating the link lengths of a six-bar linkage sley drive mechanism satisfying the required sley motion. Initially, a six-bar mechanism. is divided into a crank rocker mechanism and a double rocker mechanism and then the equations are introduced for the kinematic design and analysis. The effect of mechanism parameters on sley motion is also investigated. It is observed that the Delta phi', which is a freely chosen design parameter of the double rocker mechanism, has the most significant effect on sley motion and that the effect of crank rocker mechanism on sley motion is also significant. Other mechanism parameters have no significant effect on sley motion. It is also observed in the design trials that the practically applicable link lengths can be obtained while the sley motion requirements are being satisfied.
