A segmented die assembly (10) comprising a plurality of side-by-side and separate units (15). Each die unit, includes a manifold segment (11) and a die module (12) mounted thereon. The manifold segments (11) are interconnected and function to deliver process air and polymer melt to the modules (12). Each module (12) including a nozzle (13) through which the polymer melt is extruded forming a row of filament(s) (14). The filaments (14) from the array of modules (12) are deposited on a substrate or collector. The die assembly is preferably used to apply a hot melt adhesive to a substrate, but also may be used to produce meltblown webs.
