Abstract
The curvature of dual roller tracks is measured by centering a frame on two oppositely disposed rollers of the two tracks, and by measuring various distances and spacing parameters of the track rollers to both sides. The measurements are carried out through spindle drives and protractible feelers, all operated directly or indirectly in relation to a common reference point.
