  • a device for transporting a fibrous layer to a carding machine is known.
  • the transport route begins at a Rüttelschachtspeiser, which deposits fibers on a first conveyor belt. About another driven conveyor belt, the fiber layer reaches the circulating conveyor belt of a belt scale and from there to the collection of a card.

  • the guide rollers of the corresponding conveyor belts are parallel to each other.
  • the fiber layer is transferred unsupported from the one to the subsequent conveyor belt.
  • the structure and composition of the fiber layer distortions arise in the transfer fees, which lead by the consequent stresses to a falsification of the measurement result of the belt scale.

Below the shaft, the weight of the fibers deposited thereon is measured with a first measuring device and controlled according to the transport speed of the conveyor belt.
  • a first measuring device for example, a downstream opening unit, a constant fiber mass per unit time can be supplied.
  • This known device has, in addition to the first measuring device in the conveying direction of the fibers behind the shaft, a second measuring device. Due to the nature of the fibers caused by the behavior of the fibers within the shaft or in the filing of the fibers on the conveyor belt can not be determined by the first measuring device, the correct weight. Through the second measuring device in a region in which the fibers have left the shaft, the actual amount of fiber on the belt is measured. This primary and secondary measurement results in a differentiated control of the fiber flow.

  • the web-shaped fiber material is a fiber layer, which is deposited by a feeder (Rüttelschachtspeiser, Krempelspeiser) on a first conveyor belt. This fiber layer is then transferred to a second circulating conveyor belt, which forms a belt scale with an associated weight measuring system. Subsequently, a further transfer of the fiber layer to the collection of a card.
  • the pile formed by the carding is laid by a cross-lapper to a fleece of intended thickness.
  • the output of the cross-stacker is a surface mass, the basis weight of the nonwoven determining measuring device arranged, which operates on a radiometric principle of action.

  • a correction factor which is used to determine the weight of the located on the belt scale fiber layer.
  • a correction factor can be determined by the method according to the invention, which indicates how much the weight value of the fibrous layer in the area of the belt weigher is actually higher or lower than the measured value determined merely by means of a belt weigher.
  • the present invention also relates to a method of processing an endless stream of web-shaped fibrous material into a nonwoven web, wherein the fibrous material is produced by a feeder in the form of a fibrous layer and processed by a subsequently arranged fibrous material processing machine which is a card and a cross-stacker between the feeder and the fiber material processing machine, the mass of the fiber layer is determined by a belt weigher, wherein a circulating conveyor belt with an associated measuring system forms the belt scale, and is determined behind the fiber material processing machine, the mass flow of the nonwoven web, wherein a Evaluation unit from the mass of the fiber layer over time and the mass flow of the nonwoven web a correction value from the current, determined by means of the measuring system of the belt scale measured value calculates the actual mass value of the fiber layer, with a controller, the speed it controls the fiber material processing machine, wherein the mass flow of the nonwoven web is formed from the speed and the basis weight, and by the measured mass flow after the fiber material processing machine, the results of the belt weigher are corrected.
