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. 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. The charge measuring device is adapted to measure a charge at the measured position after the member is so rotated.

[ We claim:] [1.]1. A testing apparatus for measuring triboelectric charge applied by a material to a flexible member, where the material is operably associated and positionable with respect to the member and the material includes a portion adapted to be in intimate contact with the member at a position on an external surface of the member, comprising:a frame;a drum having an external periphery to which the member is mounted, the drum rotatably mounted to said frame;a driving mechanism including a motor for rotating said drum, said mechanism operably associated with said drum and cooperable with said member to rotate the member at least one complete revolution using the drum;a support for supporting a material in intimate contact with the flexible member, so that the material and the member form a triboelectric charge on the external surface of the member;a charge measuring device operably associated and positionable with respect to said drum for measuring voltage emanating from the member, said charge measuring device including a measuring device portion thereof positioned proximate to a measured position on an external periphery of the member, the charge measuring device adapted to measure a voltage charge at the measured position after the member is rotated the at least one complete revolution, wherein the testing apparatus measures at least one electrical property including triboelectric charge associated with the member.
