A transport system for circuit boards (12) in treatment devices (11) which runs the circuit boards (12) between pairs of rollers (20, 21). The pairs of rollers are arranged in roller tracks (17, 18) running parallel to the edge of the circuit board (12) in a narrowly defined boundary region (16). The rollers are arranged with the axes (22) and shafts (23) thereof arranged at an angle (alpha) relative to the transport direction (14) or the perpendicular (35) thereof, such as to exert a tensile force on the circuit boards in the transverse direction thereof and thus stiffening the same. Transport through treatment, for example galvanization, etching, cleaning etc., without contact with the useful region (15) of the circuit board (12) is thus possible. |
