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