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. The beam C which connects the second ends of beams A and B consists of a force transducer (FIG. 4).
