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.

A roll for a single facer comprising: (a) a hollow cylinder having an interior wall; (b) a resilient attenuating member disposed within said hollow cylinder and engaging said interior wall along substantially the full length of said interior wall; (c) said member being urged by its resilience against said interior wall to reduce the vibration of the roll and the noise level of the single facer, whereby the wall of said cylinder may be made of reduced thickness while still keeping the noise at an acceptable level.
