In the earlier papers, frictional phenomena between a running yarn and a cylindrical textile guide vibrating round its center were discussed. On the other hand, in this paper, it is described that reductiorn of friction by a textile guide vibrating vertically in a horizontal plane to yarn advancing. It is obtained from analytical consideration that the apparent frictional coefficient, namely, μ' is [numerical formula], where, a: amplitude of vibration, ω: angular frequency, V: yarn speed, θ: wrapped angle round a guide, [numerical formula], K: the complete elliptic integral of the first kind. As a result of this paper, it is proved that the vertical vibration in a horizontal plane to yarn advancing is effective in order to reduce friction apparently.
