Abstract
An apparatus for making a spunbond web has a foraminous deposition belt, a system for depositing fibers on the belt such that some of the fibers engage through the belt, and an output roller over which the belt is spanned for normally advancing an upper stretch of the belt in a transport direction toward the output roller. The output roller has a radially outwardly directed outer surface engaging the belt and formed with a profiling in turn formed by high spots contacting the belt and low spots out of contact with the belt so that fibers engaged through the belt are only pinched between the belt and the output roller at the high spots. The web is pulled downstream off the belt at the output roller.
