Abstract: An apparatus for measuring triboelectric charge applied by a material to a flexible member is provided. The apparatus includes a frame and a drum. The drum is used for mounting the member to an external periphery thereof. The drum is rotatably mounted to the frame. The apparatus also includes a mechanism including a motor for rotating the drum, the mechanism operably associated with the drum. The apparatus also includes a support for supporting the material in intimate contact with the flexible member. The material and the member form a triboelectric charge on the external surface of the member. The material includes a material portion thereof in intimate contact with the member at a first member position on an external periphery of the member. The apparatus also includes a charge measuring device operably associated with the drum for measuring an electrical field emanating from the member.

Abstract: An apparatus for obtaining measurements of the charge on a surface of a member during a period of time while applying a charge to the surface of the member is provided. The apparatus includes a frame. The member is rotatably secured to the frame. The apparatus also includes a charging device for applying the charge to the member. The charging device includes a charging device portion thereof positioned proximate to an external periphery of the member. The apparatus also includes a mechanism for rotating the member. The mechanism is operably associated with the frame. The apparatus also includes a charge measuring device operably associated with the support for measuring an electrical field emanating from the member. The charge measuring device includes a measuring device portion thereof positioned proximate to a measured position on an external periphery of the member. The mechanism is cooperable with the member to rotate the member.
