Abstract
A fabric for a papermaking machine is configured as a belt, the two side edges of which are configured in each case as closed lines. Furthermore, the belt is formed in one layer from a solid material and has pores which form passages between the two surfaces of the belt. The belt has regions with a width of approximately 400 micrometers (μm) or less. These regions extend in the longitudinal direction over the entire circumference of the belt, transversely with respect to the side edges, and include no pores formed therein.
