ABSTRACT:
A dancer assembly for establishing a plurality of pre-selected operating tensions in a moving web includes a pivotable first support member, on which a second support member is cantilevered. A dancer roller is rotatably mounted on bearings at the outboard end of the second support member. The parallelism of the dancer roller with respect to its idler rollers is maintained over the range, by matching the support members so that the torsional deflection of the first support member is cancelled by the transverse deflection of the second support member.
