Abstract

An apparatus for the continuous manufacture of a spunbond web from aerodynamically stretched thermoplastic filaments has at least one spinneret, a cooling chamber for cooling the filaments, a stretcher, and a deposition device for the deposition of the filaments to form the spunbond web. At least one filament guide having a plurality of filament-guide gaps opens toward the stretcher between the stretcher and the deposition device, and the filament guide or at least one guide part of the filament guide can be moved such that the filament-guide gap or the stretcher-side openings thereof are displaced transversely to the travel direction of the spunbond web. Thus the filaments or filament bundles guided along or through the filament-guide gap are given a transverse orientation to the travel direction of the spunbond web when deposited onto the deposition device.
