Abstract

An industrial fabric used in the form of an endless fabric belt to form and convey a nonwoven fiber web during the manufacture of a nonwoven fabric has a web-supporting surface which includes rough-surface yarns which inhibit movement, namely, slippage, of the nonwoven fiber web relative to the web-supporting surface. Preferably, the rough-surface yarns make long floats in one or both directions, that is, lengthwise and/or crosswise, on the web-supporting surface.
