Apparatus for incremental feeding of a paper web from an arborless supply roll over a transverse dancer bar resiliently supported at each end with the respective supports having different and variable spring rates to effect uneven pulling of the web during feeding and thus jogging of the supply roll. This action maintains a tight wrap of the outer layers of web on the roll and aids in maintaining web alignment during feeding.
