ABSTRACT OF THE DISCLOSURE Wire payoff devices are described which are used in conjunction with bobbin supporting cradles typically found in wire stranding and cabling machines such as high speed tubular stranders, bow or skip stranders and planetary stranders. The payoff devices include dancer arrangements each having a pair of pulley wires mounted on a common support member which is itself mounted for independent movements along two substantially orthogonal directions. One of the pulley wheels is effectively fixed and continuously releases the wire along the axis of the cradle. The other or receiving pulley repeatedly traverses the axial width of the bobbin to follow the take-off points of the wire to provide uniform take-off and prevent scraping or chafing of the wire. Movements of the receiving pulley towards and away from the bobbin as a function of the tension of the wire is translated, by means of pivoted lever arms, to a variable frictional force applied to the bobbin which substantially maintains the tension in the wire to a pre-established value.
