Abstract

An automatic dereeler includes a rocker arm that is movable between various positions to indicate the relative tension on a continuously supplied material. A sensor detects the rocker arm position which is transmitted to a controller. The controller actively controls a motor to either increase or decrease the resistive torque on a rotating axle that carries the continuous material.
