Abstract
An apparatus for measuring a thickness of a printed product conveyed in a conveying direction at a conveying speed. The apparatus includes a conveying device having a guide arrangement along which the printed product is conveyed at the conveying speed in the conveying direction, the guide arrangement including a measuring region that extends in the conveying direction of the guide arrangement. The apparatus further includes a measuring element operative to act on printed sheets of the printed product to measure the thickness of the printed product while the printed product is conveyed across the measuring region and through a measuring gap located between the measuring element and the guide arrangement. The measuring element is arranged to move toward the guide arrangement with a process timing and to move synchronously with the printed product at the conveying speed across the measuring region of the guide arrangement. The apparatus additionally includes an evaluation unit connected to the measuring element.
