  • Patent number: 6120864
    Abstract: A transfer roll cover has an inner surface made of conductive and elastic material to fit snugly around and make conductive contact with a transfer roll, and an outer surface made of looped yarns which are attached to the inner surface and have outer looped ends which make light rolling contact with a sheet transported over the transfer roll. The looped yarns are a composite of a cleaning yarn for cleaning particulate contaminants and an antistatic yarn for removing static charges from the transported sheet. In a preferred embodiment, the transfer roll cover has an inner surface made of nylon knitted yarn as a base yarn that holds the cover together and a LYCRA.TM. inlayed yarn which has an elasticity that allows the cover to stretch over and fit snugly onto the transfer roll. As an alternative, a heat-shrinkable polyvinyl acetate (PVA) yarn may be used as the elastic material. The preferred outer surface includes rayon knitted yarn with looped outer ends as the cleaning yarn, and BEKINTEX.TM.
