A line for the dip coating of objects operates with a known conveyor system. In order to avoid a collision between the objects and the hard structure adjoining the movement path, a position transducer measuring the absolute value is provided for each possible degree of freedom of movement of the object fixed to the holding frame. The course of a first boundary surface or a boundary line, which reproduces the course of the hard structures along the movement path of the object, is stored in a memory. Also stored is the course of a second boundary surface or boundary line, which runs at a distance from the first boundary surface or boundary line. Finally, the course of a contour which represents the course of the object fixed to the holding frame is also stored. The control device calculates, from the signals supplied to it by the position transducers and the other stored data, whether the contour representing the object fixed to the holding frame intersects the second boundary surface or boundary line or not and, in the first case, interrupts immediately the further movement of the object. |
