To selectively place web portions slit from a printed paper web with a left web portion above a right one over a right web portion above the left one, the parallel- arriving web portions are so guided through a turning bar looping of the right or left web about the turning bars, with superposition, which involves a 90° position change of the turning bars, and while maintaining the air cushion between the paper web and the turning bars, the level of the arriving web with respect to the first-encountered or passed over or looped about turning bar is controlled or so set that the web will engage the turning bar tangentially with the plane of the arriving web portion and delivery web portion parallel to each other, by, respectively, guiding the web portion either above the turning bar pair or from below the turning bar pair, upon 90° shift of the turning bar pair. The respective height guidance can be done by either first guiding the arriving web portion in the appropriate direction or by positioning the level of the turning bars of the turning bar pair to meet the arriving web portion in accordance with the desired looping direction of the arriving web portion about the pair of turning bars.
