    • The present invention relates to a force measuring device (20) for measuring web tensions of a running material web (10) that comprises a longitudinal direction defined by the running direction, and a transverse direction, the force measuring device (20) comprising an axle (22) and, supported on the axle, a measuring roll (30) wrapped around by the material web. Here, according to the present invention, it is provided that the measuring roll is formed as a segmented measuring roll (30) having two or more measuring segments (32) that are slidable separately on the axle (22) and are lockable in a measuring position on the axle in order to position the measuring segments (32) in the transverse direction of the material web (10) in accordance with desired measuring positions such that longitudinal sections (12) of the material web wrap around one measuring segment (32) each. The measuring segments (32) each comprise a load cell (36) that serves to determine the web tension of the longitudinal section (12) of the material web wrapped around the respective measuring segment (32) and that provides a mount with which the measuring segment (32) sits on the axle (22). The axle (22) is furnished with electrical conductors that extend substantially in the axial direction across the entire width (26), that are contactable at every position axially and with which the measuring signals provided by the load cells (36) of the measuring segments (22) are conductible to an evaluation unit arranged at an axle end (28).

    • The present invention relates to a force measuring device (10) for measuring the web tensions of a plurality of spaced apart longitudinal strips (5) of a longitudinally cut running material web that comprises a longitudinal direction defined by the running direction of the material web and a transverse direction, the force measuring device comprising an axle (12) and, supported on the axle, a measuring roll (20) wrapped around by the material web. Here, it is provided that the measuring roll is formed as a segmented measuring roll (20) having a plurality of measuring segments (22), the measuring segments (22) are arranged on the axle (12) in a respective measuring position, such that the spaced apart longitudinal strips (5) of the running material web wrap around in each case one or more measuring segments (22) and each measuring segment (22) is wrapped around by at most one longitudinal strip (5), each measuring segment (22) includes a dedicated load cell (26) for determining a web tension fraction of the longitudinal strip (5) wrapped around the measuring segment, the load cell providing a mount with which the measuring segment (22) sits on the axle (12), the force measuring device further comprising an evaluation unit (18) to which the measuring segments (22) are connected via electrical conductors and to which the measuring signals supplied by the load cells (26) in the measuring segments (22) are conductible, and the evaluation unit (18) comprising a web tension aggregation means (19) that is arranged and adapted to determine, for each longitudinal strip (5), from the web tension fractions that are determined by the load cells (26) of the measuring segments (22) wrapped around by said longitudinal strip (5), the total web tension of the longitudinal strip (5).
