Abstract
An inertia compensated festoon assembly useable to control the tension in a moving web that is subject to tension changes due to, among other things, frequent zero-speed splices of the web to a new web and that must run continuously, downstream from the assembly, at relatively high speed and under relatively constant, relatively low tensions. The assembly includes a first, inertia compensated multiple floating dancer roller festoon, in series with an isolation driven roller, and a second, inertia compensated single floating dancer roller festoon.
