Abstract: A static eliminator serves to neutralize accumulated electric static charge on a web or sheet material. The static eliminator includes a metal housing having an elongated opening exposing a plurality of corona discharge needles which are longitudinally spaced and mounted to a strip member located within the housing. The strip member is constructed of insulating material, such as plastic, and carries an elongated cable which extends longitudinally within the housing. The cable is the type having a central conductive core surrounded by a layer of dielectric material. The cable is mounted in a groove in the strip member with the groove having spaced apart conductive layers thereon. The corona needles are mounted in the strip at longitudinally spaced locations corresponding with the conductive layers. Each needle is mounted so that it makes electrical contact at one end with an associated conductive layer and extends therefrom so that its opposite end, which is tapered to a point, is exposed in the area of the longitudinal opening in the housing. The cable is terminated within the housing with the terminated end being fitted with a metal corona ball. The ball carries a radially extending electrically conductive projection which, in assembly, is inserted into the exposed end of the cable so as to make electrical and mechanical engagement with the inner electrical core to reduce corona discharge therefrom.
