    • The invention relates to a device (1) for measuring tension or a tension alteration in a paper web (5), comprising at least one measurement device consisting of a number of measurement bodies (6) and a number of fluid supply devices (2), which are intended to apply a fluid pressure to the said web (5). In accordance with the invention, the fluid supply devices (2) are so arranged as to subject the web to an essentially constant fluid pressure in order to provide a fluid cushion between the web (5) and the measurement bodies (6), the measurement bodies (6) are so arranged as to apply pressure to the web (5) without making contact, the said measurement bodies (6) are so arranged as to be capable of displacement, and the position of the said measurement bodies (6) in the normal direction of the web (5) is altered depending on variations in the constitution of the web (5). The invention also relates to a method for measuring web tension and a machine comprising a device for measuring web tension.
    • 本发明涉及一种用于测量纸幅(5)中的张力或张力变化的装置(1),包括由多个测量体(6)和多个流体供应装置(2)组成的至少一个测量装置, ,其旨在将液体压力施加到所述纤维网(5)。 根据本发明,流体供应装置(2)被布置成使幅材基本上保持恒定的流体压力,以便在幅材(5)和测量体(6)之间提供流体衬垫,测量 主体(6)被布置成在不接触的情况下对腹板(5)施加压力,所述测量体(6)被布置成能够移位,并且所述测量体(6)的位置 纸幅(5)的法线方向根据纸幅(5)的构成的变化而改变。 本发明还涉及一种用于测量幅材张力的方法和一种包括用于测量幅材张力的装置的机器。
