Abstract
An apparatus for measuring the thickness of flat products such as sheets or signatures, the flat products being fed from a pile of signatures to a pocket by a pocket feeder. The pocket feeder includes a first and second roller. The first roller is arranged against the second roller to form a nip therebetween for receiving a flat product. The first roller is deflectable when a flat product enters the nip. The apparatus comprises a first proximity target which is arranged on the first roller and a second proximity target which is fixedly arranged on the receiving unit. A proximity switch monitors the targets and a control unit starts and stops counting the pulses generated by an encoder. To calculate the thickness of a flat product, the counted pulses are compared to a stored value.
