Abstract
The interior wall of a hollow corrugating roll or a hollow pressure roll of a single facer is frictionally engaged by a resilient member so as to minimize the elastic vibration thereof and thereby to minimize the noise developed and transmitted during operation of the single facer. The resilient member is positioned within the hollow interior of the roll and is arranged to press against the interior wall as a result of its resilience and thereby to reduce the elastic vibration of the roll and the noise transmitted. The resilient member may take various forms, such as a coiled helical spring, a coiled leaf spring, a plurality of tapered nested annular members engaging the interior wall of the roll, et cetera.
