Liquid finish is applied to a travelling filament by bringing the travelling filament into contact with an arcuate surface portion associated with a normally stationary, but rotatable, annular finish applicator, and thereafter periodically rotating the annular finish applicator to bring at least one other arcuate surface portion thereof into contact with the travelling filament. Most preferably, an actuator assembly is provided having first and second actuator fingers which are capable of relative separable rectilinear movements towards and away from one another. These actuator fingers, in an especially preferred embodiment, are each pivotally moveable and magnetically coupled to one another. As such, separable movement will in turn cause that one of the actuator fingers connected to the annular finish applicator to pivot thereby rotating the later to expose a "fresh" arcuate surface region in contact with the filament.
