Abstract (en)

[origin: EP0686502A2] The device includes a drive which applies a variable force and a transmission which converts the drive force into a pretensioning force acting on the roller to counter the bending load. The transmission has a rotatable crank which connects with roller in the area of the journals and which extend, on the machine frame side of the journal bearing or between the bearing and the frame. The transmission has a device attached to the frame and the drive crank which can apply a compressive or tensile load. The device is pref. in the form of a rigid plate which can lock the crank at a pre-set angle. <IMAGE>
