ABSTRACT:
A caliper for measuring the thickness of collated printed products and which has a lever arm which is pressed into engagement with each of a plurality of printed products as they are serially conveyed past a measurement station. The lever arm is actuated by a servo motor which includes an encoder, and when the lever arm is pressed into engagement with each product, the position of the lever arm is sensed by the encoder which then delivers a signal to a controller where the thickness is calculated and compared with a predetermined correct value. A method of calibrating the caliper is also disclosed.
