Abstract: The invention relates to a device for measuring the pressure between two rollers tightly placed against one another or the deformation caused by this pressure in their mutual contact area. The invention is for use in the fields of machines and mechanical assemblies comprising rollers pressed against one another, for example, in printing presses or rolling machines. A crushing width can also be measured, for example, for a deformable seal or a line of glue or cement in an assembly process. This device comprises a thin sensor to be inserted between the rollers and whose shape has a return (14) provided in such a manner that, when the sensor is in a measuring position, the mechanical connections (131) connecting the sensor to the maneuvering part are situated in the squeezing area or on the side opposite the maneuvering part with regard to the squeezing area (ZP).

Abstract: An upholstered body, especially mattress, with a spring core which is provided with at least one cover plate of elastic foam material, and has on at least two opposite sides thereof inwardly of the plate respectively arranged a marginal body member of elastic foam material. In the transition area between the cover plate or cover plates and the marginal body members on at least two oppositely located sides of the upholstered body, there are provided bend-elastic bar-shaped stiffening bodies which consist substantially of compacted synthetic foam material, preferably of the same type the marginal body members are made of and preferably integral therewith. These stiffening members are located at the inside of the adjacent cover plate. Interposed between the at least one cover plate and the adjacent ends of the springs is an intermediate layer having its marginal areas connected to the stiffening bodies.
