APPARATUS FOR PRODUCING A NONWOVEN WEB

摘要

In the production of a spunbond web by aerodynamically stretching thermoplastic filaments from a spinneret, the drawing nozzle is formed by two nozzle-forming units each of which has a temperature control device, especially a heater, to minimize deformation at the drawing nozzle defining wall. The result is a reduction in the tolerance of the basis weight of the spunbond web.
