  • Patent number: 7445693
    Abstract: Two axially parallel rolls are pressed against each other in a device for producing and/or treating a moving material web. Sensor elements are arranged in the force transmission path running from the force-producing elements via the rolls, outside roll bodies of the two rolls. As a result of displacing the sensor elements out of the roll bodies of the rolls, the production of the rolls is less complicated and less expensive. No sensors have to be embedded in the roll bodies, which opens up the possibility of using standard rolls. In addition, the occasional grinding of the rolls can in this way be performed without any regard to the sensor elements. Nevertheless, the pressure prevailing between the rolls can continue to be measured directly, since the sensor elements are arranged in the transmission path of the pressing force.

  • Patent number: 7431802
    Abstract: The invention relates to a forming fabric, with a paper side fabric having paper side threads and with a wear side fabric having wear side threads. The paper side fabric and the wear side fabric are superimposed to one another and connected by binding threads weaving with both the paper side threads and the wear side threads, both extending in cross direction relative to the binding threads. The binding threads form part of the weave pattern of the paper side fabric and form part of the weave pattern of the wear side fabric, and alternate from weaving with the paper side fabric to weave with the wear side fabric and vice versa, thereby crossing each other forming crossing points. The wear side weave pattern is repeated by wear side repeat units, wherein the binding threads alternate such that one or less than one crossing point within each wear side weave repeat unit is formed and the ratio of the paper side threads to the wear side threads is greater than 1.

  • Patent number: 7428786
    Abstract: A method for manufacturing a fiber web having a three-dimensional surface structure and a strength. The method includes the steps of pre-imprinting the fiber web, pressing the fiber web and forming the fiber web. The pre-imprinting step pre-imprints the fiber web at a dry content of less than 25% with an imprinting band using a first pressure field. The pressing step presses the fiber web onto the imprinting band using a second pressure field. The pressing step further dewaters and dries the fiber web fixing the three-dimensional surface structure and the strength. The forming step forms the fiber web on the imprinting band.
