  • the invention relates to a device and a method for fiber treatment with the features in the preamble of the main claim.
  • the fleece layer enables the production of a profiled fleece with a density or thickness that varies over the laying width.
  • the profiling is achieved by the speeds of the pile leading drives of the fleece layer being uniform compared to the constant pile delivery speed of the upstream
  • the pile is subjected in the region between the carding machine and a lapper delay ', where it is preferably stretched.
  • the pile parts with the warping are then deposited on the take-off belt at the desired locations after passing through the nonwoven layer, whereby the aforementioned profiled nonwoven is formed. Due to the fluctuations in the speeds of the pile-leading drives of the fleece layer, the pile is also released on the output side at a fluctuating speed. If the subsequent consolidation device, for example a needle machine, requires a constant feed speed, a buffer device is connected between the fleece layer and the needle machine to compensate.
  • Buffer devices increase the construction and space requirements and make it more difficult to modernize existing fiber treatment plants with the components mentioned.
