Abstract: The invention concerns a measuring idler-roller for measuring stress distution of flexible bands that are moved in the direction of their length, in which roller force-measuring transducers arranged in recesses or their covers are surrounded by a plastic layer that fills in a gap and prevents the penetration of fine abraded metal particles, and makes easier the installation of the cover and/or the measuring transducer.

Abstract: In an apparatus for straightening metal strip comprising guide rolls arranged parallel to one another a straightening roll is arranged in the gusset space between two guide rolls which has the strip wrapped round it in a form-fitting manner between two lines of contact along which the guide rolls are in indirect contact with the straightening roll. This makes it possible to straighten even high-strength strip without the need to apply tensile loads which exceed the magnitude needed to transport the strip through the apparatus.

Abstract: A deflecting roller for sensing the distribution of stress along the roller while the roller deflects a strip of sheet material, and in particular, a deflecting roller having a plurality of stress sensors disposed around the roller such that the stress sensors sense the radially acting force on the roller, without contributing any interfering forces thereto. The roller has a plurality of measuring locations defined about the circumference of the roller. Each measurement location includes a recess in the roller; a stress-responsive sensor disposed in the recess; and a sensor cover positioned within the recess so as to cover the stress-responsive sensor. The sensor cover has the same cross sectional shape as the recess so that the sensor cover is guided by the wall of the recess for radial movement with respect to the roller. The sensor cover does not rest on a shoulder in the recess.

Abstract: A deflection measuring roller includes mutually non-rotatable rings having orce sensors for determining the stress distribution of undirected, flexible strips. A receiving chamber is made of a window which is formed in the material of the annular wall and within which the force sensor and wedge are provided.

Abstract: A device for measuring stress distribution across the width of flexible litudinally moving strip material, such as strip steel during coldrolling. The device includes a deflection measuring roller comprised of a plurality of rotatable sections mounted side-by-side. Some of the sections have force pick-ups fitted therein and the elements cooperatively function to detect and measure deflection as an indication of stress distribution across the strip.

Abstract: Apparatus for measuring stress distribution across the width of a flexible strip travelling in the direction of its length, comprising a pick-up deflector roller having a plurality of rings, encased in a tire of flexible material, the edges of the rings being cut away to produce local stress in the tire as compared with a smooth cylindrical roller.

Abstract: An arrangement for measuring stress distribution over the width of a longdinally moving flexible strip wherein there are provided force transmitters and a deflection measuring roller made up of closely adjacent rings running with the strip under stress and reacting upon said force transmitters, wherein the force transmitters produce parallel switching output signals and rotate in a distortion-free position with said rings which are secured relatively to each other against distortion, the force transmitters being offset peripherally relative to adjacent rings and being connected in parallel circuit groups to a common rotation transmitter for which the output is designed for measurement value processing.
