A speed control assembly for a rotatable web winding apparatus comprising a dancer engaged with a web of material wound about the winder apparatus for displaceably responding within a predetermined range of dancer positions to tension variations in the web; a first control signal generating device for generating a first control signal in response to dancer displacement from a predetermined centered position, the ratio of dancer displacement to the first control signal being variable over the range of dancer displacement positions; and a dancer response rotation control device for rotationally accelerating the winding apparatus in response to the first control signal.
