Abstract
An apparatus for producing spun-bond fleece has the process shaft connected to a source of process air and opening into a depositions shaft centrally thereof and flanked by streams of air bypassing the process shaft. The result is a random jumbling of the fibers as they deposit on the moving belt such that a uniform filament density and homogeneous mesh width are obtained without singularities and without conglomeration of the filaments in the shafts.
