Abstract: An apparatus for the spooling, storage and dispensing of reels of wire in which thre is provided means for measuring the pulling force on the wire so that the speed of rotation of the reel is in proportion to this pulling force. In one embodiment this comprises three pulleys, two fixed and the third movable towards and away from an in-line position between the pulleys under the influence of the tension imparted to the wire. The movable pulley is connected to a potentiometer which controls the speed of an electric motor used to drive the reel.
