Abstract: The invention relates to a coating device (100) with movable spray nozzles comprising a rotating drum (3) and positioning group (1) of a set of spray nozzles (21) for a product with a control column (5) able to be located essentially axially inside the drum (3) and which houses an inner shaft (6), the control column (5) being equipped with at least an articulated arm (7) that includes a rotating nozzle set (21) carrier (20). A transmission system (30) based on pulley means and corresponding pulling means housed in the control column (5) and in the articulated arm (7) simultaneously produce the contraction or extension of the articulated arm (7) and the rotation of the nozzle set (21) carrier (2) based on the relative angular position between the steering column (5) and the inner shaft (6).
