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. conductive knitted yarn with looped outer ends as the antistatic yarn.
