Abstract
A belt made up of an elastomeric belt body, an electrically conductive tensile cord such as carbon fiber cord in a cord layer reinforcing the belt body, an outer layer of electrically conductive thermoplastic material such as polypropylene film, and an electrically conductive fabric layer residing between the tensile cord layer and the outer layer and providing electrical continuity between the outer layer and the tensile cord. An electrically conductive thread may be woven in the fabric and may present at both surfaces of the fabric and contact both the outer layer and the tensile cord to provide the electrical continuity there between.
