ABSTRACT:
A spun-bond apparatus has at the lower edge of the diffuser below the filaments stretching shaft, cooler and spinneret, partitions which run from the lower edge of the diffuser to upper rollers and pressing roller pairs upstream and downstream of the diffuser along the perforated collecting belt on which the spun-bond web is formed. These partitions parallel to the belt and spaced 15 to 50 mm from the collecting surface have been found to limit turbulence which tends to affect the structure of the web in earlier spun-bond fabricating apparatus.
