Abstract
Apparatus and method for counting the number of inserts pulled each cycle from each hopper of an inserting machine. The caliper is a precision mechanism for accurately counting single, double, triple, quadruple and even quintuple fed inserts as well as misses. The caliper system compensates for a wide range of variables and countered in conventional newspaper inserting machines operating at 400 cycles per minute. The set-up of the caliper system is highly simplified due to the system software which, in addition to while proving a learn zero and learn insert mode, further recognizes operational variables which occur during operations such as fluctuation of paper basis weight and ink build up on the caliper wheel. The system provides self-checks to verify operational accuracy.
