  • the third embodiment of a wadding machine 10 according to Figure 15 corresponds to the embodiment of Figure 14, wherein the pressure rollers were removed, so that the slivers 3 are drawn to form a cotton by the drive device 21 exclusively by two superchargers 8, 8 ' , there duplicated and smoothed and stored in a rectangular storage can 20.

Also, this embodiment allows an inexpensive and structurally simple embodiment of a 15 Wattenmaschine 10, with a first layer of slivers 3, on which a second layer slivers 3 are laid on it, is formed into a wadding as a template for a combing machine.
  • the resulting cotton has a width corresponding to the width of the rectangular storage can 20.

  • the Wattenr when removing from the storage can not fray, but retain their geometric contour from the cotton wool machine.
  • the lateral inner surfaces of the can support the formation of the lap edge. For example, if the cotton broader enters the pot, as the width of the pot, the edge of the pot Wattenr may be turned over and then guided on the side surfaces.
  • the wadding machine has means for detecting the moisture content in the fiber material in the wadding machine.
  • the pressure of the pressure rollers 4a-4c, the plunge depth of the supercharger 8 and / or the speed of the drive device can be adapted.
  • the material moisture is the deciding factor. It has been found that too low moisture of the fiber material has a negative influence on the processability of the fibers.
  • the invention makes use of the knowledge that, for example, cotton is better to process in a wet state, as in a dry state, since the strength increases, at the same time the fiber stiffness and friction decreases.
  • the setting of the cotton machine in which the material speed, the pressure on the pressure rollers, the delay between the pressure rollers and / or the plunge depth of the supercharger are optimized.
  • the webs can interlock in the supercharger, for example, 5 mm deeper, so that the sliver is more aligned and smoothed.
  • optical measuring sensors can be used as measuring devices whose radiated light is absorbed by the moisture content of the material.
  • microwave-based measuring systems can be used which measure the moisture content of the material.
  • the measuring device is integrated, for example, in the pressure rollers. This results in a sufficient controlled system, for example, to control the material speed, and / or the plunge depth of the supercharger.

  • the observance of an optimal processing climate for all process steps is not or hardly realizable.
  • the invention continues, thereby adapting the machine parameters to the existing spinning climate.
  • the default machine parameters can only be changed if a so-called threshold value is exceeded or exceeded. For example, lowering the relative humidity from 60% to less than 40% can lower the material speed. If the relative humidity of the air is lowered from, for example, 60% to 55% and then to 50%, alternatively the penetration depth of the webs of the supercharger can be increased step by step without the production capacity being reduced.
  • the regulation or control over a threshold value has the advantage that the operator of the wadding machine does not have to take into account certainties in the selection of the machine parameters, but can select optimal parameters adapted to the material. This can be achieved with optimal spinning climate a higher cotton quality or increased production speed
  • the machine parameters can be changed together or individually to ensure adequate product quality. On the other hand, this ensures that the optimal condition of the slab machine drives with the highest productivity.
  • the wadding machine has a database in which the optimum climate data are stored for different fiber types.
  • the associated control algorithm can also be stored in the database with which settings the wadding machine travels in the event of a deviation from the optimum climatic data.
  • the threshold values for each type of fiber can be deposited, which must be exceeded or exceeded, so that the cotton machine drives with different operating parameters.
  • the database can be part of a control / regulation in which the measured humidity as a control variable is used as an input variable, is compared with the optimal humidity as a reference variable, and the control / regulation by means of a signal an actuator operated, for example, the speed of the drive motors of the drive device 21 acts.

Abstract
