Abstract
The tracking signal generating device disclosed herein is adapted to be utilized between successive conveying sections in which articles are transported at a nominal height. A resilient suspension supports an elongate roller so that it projects above the nominal height of the conveying sections in the absence of an article being transported, but is deflected downwardly by the passage of an article from one section to the next. A sensor responsive to the downward deflection provides a signal indicating the presence of an article and an encoder driven by rotation of the roller generates signals indicating the length of an article passing the device.
