Arrangement for correcting the fan-out effect on web-fed printing presses

Stress in a paper web in a rotary printing press is measured by directing the web past two tubular members spaced in the direction of web travel and supported by support arms. Deflection of the support arms is measured and provides an indication of the amount of stress in the paper web.

A bearing journal for a paper guide roller has a blind bore extending inwardly from an axial outer end. The blind bore carries cooperating clamping wedges which are slidable with respect to each other to thereby radially expand an annular clamping area of the bearing journal into engagement with a side wall of the printing press.

A method for preparing paper samples for determination of physical characteristics includes immersing the samples in a water-solvent mixture and then allowing the solvent to evaporate. The paper samples are thereby provided with a particular water or dampness content and can then immediately be subjected to testing on a tension testing machine or similar device.
