  • Patent number: 10324101
    Abstract: Apparatus for automating a high volume instrument (HVI) used for the classification of all Upland and American Pima cotton, including determining trash and color. A sub-sample delivery tube sub-system and a sample drum air chamber sub-system allow the HVI to receive sub-samples from an automated cotton system. A delivery tube, with an air dissipater, delivers the automated sub-sample to the HVI sample drum while an air chamber below the sample drum applies a negative air pressure to the drum. A sub-sample air-knife extraction sub-system and an autoMIC transfer tube assist sub-system allow the HVI to release automated sub-samples after the sample drum in the HVI has completed its operations on the sub-sample. An air-knife applies air jets to the sample plate of the HVI sample drum to release the sub-sample. As the sub-sample leaves the drum an air jet is actuated to push the sub-sample along a transfer tube.

  • Fan
    Patent number: 9903380
    Abstract: A fan for a ventilation system has a motor, a motor speed control unit and a controller arranged to control the motor to maintain the quantity of air flowing through the system constant. The controller compares the actual motor current with an expected motor current for the fan operating at the desired air quantity and motor speed to determine an actual system operating condition. When the difference between the actual motor current and the expected motor current is greater than a preset range, the motor speed is adjusted to a new motor speed determined based on the actual system operating condition. The system operating conditions may change due to changes in the static pressure of the system such as changes to the ventilation ducting or external wind pressure.

  • Patent number: 6704969
    Abstract: An endlessly circulating conveying device is provided for strengthening a conveyable fiber lap. The device has first and second converging rollers for conveying the fiber lap. Each roller has an outer surface and at least the first roller is provided with profile elements on its outer surface. The rollers are for subjecting the fiber lap to a pressure when the fiber lap passes through a gap between the rollers, and strengthening the fiber lap by exerting the pressure by the converging rollers and the profile elements.

  • Patent number: 6615455
    Abstract: A fiber opening device comprising a feed section opening into the fiber opening section. The opening section includes a cabinet with an inner chamber, a waste removal chamber and a fiber web removal unit. The inner chamber includes a doffing roll and a contaminant collecting area located above first and second opening rolls. A main roll is located beneath and between the opening rolls and a waste removal section and a fiber web removal section are located beneath the main roll. In operation, fibers delivered into the inner chamber are first acted on by primarily one of the opening rolls which creates a tumbling action in which contaminants are dislodged and deposited into the contaminant receiving area while other fibers are picked up by the second opening roll carried to and doffed onto the main roll forming a fiber web for delivery to the fiber web removal section.

    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.
