Abstract: A load cell comprising a load carrying structural framework is arranged with at least one measuring zone (15, 16) arranged with a measuring means. A load F applied in the x-direction parallel to two outer beams (1, 4) of the framework is transferred to two inner beams (2, 3) by two side beams (5, 6). The load on the measuring zones (15, 16) is greater than the load applied parallel to outer beams (1, 4) in a ratio of the distance b between the joints of the two outer beams divided by the distance d between the joints of the two inner beams. When a load is applied in the y-direction parallel to the two side beams (5, 6), the load on the measuring zones is also greater than the load applied at the side beams, in this case by a ratio of the distance l between the joints (7 and 11), (10 and 14) divided by distance d.

Abstract: A load cell comprising a load carrying structural framework is arranged with two measuring zones (20, 21) where a measuring means is arranged on each. A load applied to two parallel outer beams (10, 11) of the framework is transferred to a third parallel measuring beam (17) arranged with a measuring zone (20) by connecting beams (12, 13). The connecting beams (12, 13) make an angle &agr; to the long axis of the measuring beam (17). The load on the measuring zone (20) is greater than the applied load on outer beams (10, 11) in proportion to the angle &agr;. A preferred embodiment of the load cell comprises a membrane (34) joining each measuring zone (20, 21). In a load cell according to a preferred embodiment of the invention measuring zones (20, 21) are defined by passageways (43-48) and slits (35-38) running from one side of the load cell to the other in the z-direction. A load to be measured is applied in the y-direction.

Abstract: For measuring tensile force in a continuous strip or web, load cells are arranged between a bearing housing for a deflector roll, over which the web runs, and a fixed base. A load cell comprises a load cell housing and consists of two yokes (1, 2) facing the bearing housing and the base, respectively, and a force transducer which together with membranes (3 . . . 6) are arranged between the yokes to connect these together. At the end plates of the yokes, screw holes (8 . . . 15) are provided to attach the yokes to the bearing housing and the base, respectively. At each screw hole there is provided a gap (16) so that, around each screw hole, a tubular body is formed and that the plane outwardly-facing surfaces (17) of the bodies are plane-parallel and extend outside the otherwise plane outwardly-facing surfaces of the yokes.

Abstract: A flatness measuring device for rolled strip (5) according to the invention comprises a measuring roller over which the rolled strip passes. The measuring roller is divided into a number of roller sections (6). The forces on the roller sections are measured and can then be converted, via recalculations, into a measure of the flatness of the strip, whereby a flatness profile across the strip can be obtained. Special to the invention is the method of measuring the force. Between each roller section (6) there is a side member (ABC) which supports the shaft ends (7) of two adjacently positioned roller sections. The side member in principle consists of three beams (A, B, C) connected together in the form of a triangle. The beam A for all the side members is attached to a common plate (1). The first ends of the beams A and B connected together via a flexible diaphragm (2). At the second end of the beam B the shafts are journalled.
