  • Tempering means in the context of the invention means for heating or cooling of a stretching nozzle.
  • the tempering is a heater for heating the Verstreckdüsenaggregates.
  • the term heating device is used instead of the term tempering device, although the technical features explained below can in principle generally also apply to a tempering device.
  • the heating of the stretching nozzle assemblies is carried out with the proviso that a temperature difference between the temperature in the stretching nozzle gap and the process air temperature in the stretching nozzle gap and the ambient temperature is compensated and a deformation of the stretching nozzle assembly resulting from this temperature difference is counteracted.
  • the entire draw-jet unit can be heated to the process air temperature or to the temperature in the drawing-die gap.
  • the invention is based on the knowledge that, given differences between the temperature in the stretching die gap and the ambient temperature, deformations can occur or occur on the stretching die assemblies, and the stretching die assemblies then bulge, in particular in their middle towards the die gap.
  • the invention is further based on the finding that due to such deformations of the draw-jet aggregates or of the nozzle-gap-side inner surfaces of the draw-jet aggregates, the differences in the basis weight of a spunbonded nonwoven web occur.
  • the undesirably high basis weight tolerances which occur in the devices known from the prior art, an immediate consequence of the deformations or bends of the stretching jet aggregates.
  • At least one heating device for heating the Verstreckdüsenaggregates is provided at each Verstreckdüsenaggregat.
  • the temperature differences can be compensated within the Verstreckdüsenaggregate and thus avoided the deformations or at least reduced sufficiently.
  • the temperature in the drawing die gap or the temperature of the process air in the drawing die gap is higher than the ambient temperature (for example about 20 ° C.).
  • the draw-jet aggregates then bulge with their nozzle-gap-side inner walls, as a rule, toward the nozzle gap. This can be avoided by the heating according to the invention.
  • the draw-jet unit is heated to the temperature in the nozzle gap.
  • At least one temperature sensor is provided for measuring the ambient temperature and, in accordance with the measured ambient temperature, the heating of a stretching nozzle assembly takes place.

It is within the scope of the invention that the control and / or regulating device is used to heat up a hiding-machine aggregate in accordance with the measured ambient temperature. It is also within the scope of the invention that a measuring device is provided for measuring the temperature in the stretching nozzle gap or the process air temperature in the stretching nozzle gap. Then can be made in accordance with this measured temperature with the control and / or regulating device, the heating of a Verstreckdüsenaggregates.
  • a device for determining the weight per unit area of a spunbonded nonwoven web produced is provided and the heating takes place as a function of this determined basis weight.
