  • Device such as a carding machine for processing fibres
    Patent number: 6996878
    Abstract: The present invention relates to a device, such as a carding machine, for processing fibers, said device comprising a cylinder, which is provided with a lining, and at least two carding segments which are arranged one after the other in the direction of rotation at least over an area of the circumference of said cylinder, each of said carding segments being provided with a toothed lining. The present invention aims at improving the efficiency of such a device especially in terms of fiber parallelization.
    Type: Grant

  • Method and apparatus for fiber length measurement
    Patent number: 6611994
    Abstract: The present invention relates to the application of fiber length measurement in the blowroom or carding room of a spinning mill. A method and an apparatus in a textile processing machine are described in which before and/or after a working element of the textile processing machine the nep count and/or the fiber length (staple) is determined, with an open-loop/closed-loop control unit being provided which receives the values for the fiber length and/or the nep count as input and determines therefrom the optimized machine setting data and outputs the same to at least one actuator of a working element which influences the nep count and/or the staple of the textile processing machine.
