Abstract (en)
[origin: DE19506456A1] A control device (3) for monitoring the travel of two superimposed paper webs (1, 2) in a paper processing machine has a thin stationary plate (4) arranged at the edge of the paper webs (1, 2) that extends between both paper webs in the direction of travel of the paper. Reflection-sensitive photoelectric sensors (5, 6) are arranged on opposite sides of the plate (4) so that the light rays (5a, 6a) from both sensors are projected from opposite directions upon the corresponding paper web (1, 2) and the plate (4) located behind the paper web.
