How the Erhardt+Leimer RK 4004 Works

The RK 4004 uses optical or ultrasonic sensing technology to detect the edge of a moving web material, continuously monitoring its position and relaying signals to a controller. When deviations occur, the system adjusts the material’s position via actuators or motors, keeping alignment within specified tolerances. This real-time correction improves production accuracy, reduces material waste, and boosts operational efficiency — making the RK 4004 an essential component for industries that demand precision in web handling and consistent product quality.
