Definitions

  • the invention relates to a system for opening and cleaning fiber material, as well as a corresponding procedure.

  • a cleaning line delivers material to a predetermined number (e.g. twelve) of cards.
  • the line must be designed to meet the maximum demand of its connected To meet cards. As the performance of each card increases strived to adjust the performance of the blowroom line accordingly (i.e. a reduction in the number of cards connected to a blowroom line is undesirable).
  • DE-A-2532061 is concerned with the dedusting of cotton for use in the rotor spinning machine is provided. There is an additional one in the filling shaft Cleaning provided, i.e. the material is already in the upstream machines have been cleaned according to known principles. In other words, it wasn't planned to give up the fine cleaner and this was actually not done in practice.

If the intensive opening (dissolving) for purposes other than cleaning must be provided (e.g. when mixing), the invention does not directly affected. However, the total load of the material reduced, which at most the use of the clamping power in connection with functions other than cleaning.
  • Fig. 1 shows schematically a blow room line of known design.
