ABSTRACT:
A measuring device for checking the dimensional accuracy of the track width of curved transport tracks formed by paired rollers lying on a radius of curvature equidistantly be placed into a transport track and moved therealong, is provided with at least two displacement sensors. The sensors are spaced apart at a distance determined by the track width. The carrier for the displacement centers has contours corresponding substantially to the curvature of the transport track. The carrier has a length which ensures, when inserted in the transport track, the continuous spanning of at least two successive roller pairs. The displacement sensors are located on a radius of the circle of curvature of the track. The height of the carrier corresponds substantially to the track width, and the sensors are of the non-contact type. The carrier may be coated with elastically resilient material on those surface portions subjected to reciprocal action with the rollers.
