Measuring device for measuring the thickness of sheet material like bank-notes has a multitrack thickness sensor with two opposing fixed shafts driven synchronously

摘要

Scanning rollers (SR) (2) and counter rollers (CR) (4) oppose each other and sit on fixed driven shafts (1,3). They also run while touching each other and form a conveyor gap. The CR have a fixed material with a stable dimension (SD). The SR have a soft elastomer (7) with a fixed outer ring (6) with an SD.
