ABSTRACT:
To determine the deviation of two juxtaposed cylindrical rollers from parallelism of their axes, the angle included between a reference direction (e.g. vertical) and a line tangent to the roller surfaces is measured and the process is repeated at another location axially spaced from the first one. The method is particularly applicable to calendering rollers in paper-making machinery or the like.
