A nozzle has a body having a face extending in a longitudinal direction and transversely thereto in a transverse direction. The nozzle plate is provided with an array of melt openings and compressed-air openings on the face in a plurality of longitudinally extending rows and a plurality of transversely extending rows. A polymer melt to the nozzle openings to extrude the polymer melt downstream from the melt openings as polymer filaments and compressed air to the compressed-air openings to form air jets issuing downstream from the compressed-air openings between the polymer filaments. Only the polymer melt and no air is supplied to the melt openings such that only the polymer melt issues from the melt openings. Only compressed air and no polymer melt is supplied to the compressed-air openings such that only the compressed air issues from the compressed-air openings.

Nozzle for making meltblown filaments

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.
