摘要：
A belt to be used in paper-machine wet-pressing, in particular in a machine with an extended pressing gap, includes a flexible, liquid-impermeable belt stratum which is smooth on its back side.This belt is improved by providing the front side of the belt stratum (2,12,25,36) with a structured surface with open longitudinal and/or transverse channels (9,14,30,41), for the purpose of water drainage, which cannot be squeezed, or only insignificantly, under press compression.
