Xerium roll venting system for tissue machines

摘要

Xerium Technologies has launched EnerVent, a new roll venting technology for tissue machines. EnerVent, which has a patent pending, utilises an innovative combination of roll grooving geometry which provides increased nip dewatering with softer, wider nips. It is specially engineered for rubber covers applied to tissue suction pressure rolls, and is already reducing energy costs and increasing machine speeds for existing tissue producers. The EnerVent system considers felt design, vacuum capacity and water handling capability, providing an engineered venting pattern of suction holes and grooves to maximise both water removal and roll cover life.
