An apparatus for making nonwoven has a mesh belt moving in a horizontal direction and upstream and downstream spinnerets spaced apart in the direction above the belt and having downwardly opening tips at respective vertical spacings above the belt and each emitting fibers that are deposited at locations on the belt directly below the spinnerets to form thereon respective nonwoven layers. A support carrying the belt can be moved vertically and pivoted to orient the belt into a position forming an acute angle with respect to horizontal and thereby vary the spacings.
