Abstract
A fabric belt on which, when used as intended in a machine for producing spunbonded fabric webs, such spunbonded fabric webs are formed and transported. The belt has longitudinal threads and transverse threads that bind with the longitudinal threads. The threads are formed substantially of a polymer material and some of the longitudinal and/or transverse threads include electrically conductive material. The longitudinal threads form, on the web material contact side, convex longitudinal thread offsets with a knuckle, and the transverse threads have first transverse threads which form, on the web material contact side, first transverse thread offsets with a knuckle. A height difference between the knuckle crowns of at least some of the convex longitudinal thread offsets and the knuckle crowns of at least some of the first convex transverse thread offsets on the web material contact side is less than 220 μm or even less than 150 μm.
