Abstract
A v-ribbed belt manufactured in a molding or grinding process has in different areas of the structure thereof different elastomer materials. In upper rib segments oriented toward the belt pulley there is an elastomer material that is not electrically conductive. The lower rib segments are made of an electrically conductive elastomer material. The height ratio a/(a+b) of the height (a) of the lower rib segments to the overall height (a+b) of the rib, as measured at the material boundary located at the rib flank, is at least 6 percent, or the absolute height of the lower rib segments is at least 0.12 mm.
