In a system for adjusting the height of a station for feeding items in a packaging machine, in which the feeding station has an outlet conveyor for the articles being delivered to other working stations of the packaging machine, the working stations are adjusted in height with respect to a common zero reference plane by a control unit. A lower stationary framework carries the item feeding station, while an upper moving framework is interposed between the feeding station and the lower stationary framework. A driving belt is powered by a motor for moving the moving framework with respect to the stationary framework. The motor is connected to the control unit for receiving an activation command corresponding to a height for the outlet conveyor determined in dependence of the height imposed to the other working stations. The driving belt move the moving framework vertically with respect to the stationary framework to position the outlet conveyor at a selected height with respect to the reference plane.
