ABSTRACT:
Apparatus for discriminating signature sets of abnormal total thickness from signature sets having normal total thickness in a saddle-wired preparing apparatus. The discriminating apparatus includes means for electrically detecting the movement of sensor wheels which are adapted to discriminate a signature set of normal thickness from one having abnormal thickness, means for timing the output of this detected signal through a mechanical detector, and solenoid means for switching a stitcher and a deflector lever.
