Abstract (en)
[origin: WO2016020230A1] The invention relates to a fabric belt for producing web material, in particular for producing spunbonded fabric, comprising a plurality of longitudinal threads (12) which run substantially in a belt longitudinal direction (L) and a plurality of transverse threads (14) which run substantially in a belt transverse direction (Q). The longitudinal threads (12) are laced with the transverse threads (14) at lacing points (18); peak regions (20) of the longitudinal threads (12) are formed on a web material contact face (16); and a plurality of deposits (22) are provided at least on the longitudinal threads (12) on the web material contact face (16). The invention is characterized in that deposits (22) are provided which do not extend in the peak regions (20), and/or deposits (223) which extend into the peak regions (20) are non-symmetrical with respect to a respective peak region (20) in the belt longitudinal direction (L).
