For transforming a supply stream (2), in which stream elements (1) each comprising one flat object or a group of flat objects lying on top of one another, are conveyed overlapping one another, and in which the stream elements are essentially oriented parallel to the con- veying direction (F), during unchanged onward conveyance, every stream eleme nt ( 1 ) is gripped in a same location which in the conveying direction (F) is situated in the centre of the element and in which location the element is not overlapped by adjacent elements (1) and every stream element is then displaced transverse to the conveying direction (F), the spatial element orientation remaining essentially unchanged. The displacemen t is different for successive stream elements (1) in a predefined sequence. For gripping th e stream elements (1) in a clamping manner, in particular clamping elements (5.1) are used, which are capable of being displaced transverse to the conveying direction (F) alo ng guide links (6). As the displacement of the clamping elements (5.1) in the predefined sequence is easily controlled by stationary cams, the device is very simple. The stream transformation is suitable in particular for transforming a supply stream (2) with stream elements (1) each comprising a plurality of objects (e.g. printed products) having different formats and lying on top of one another and overlapping one another in the supply stream (2) t o produce a stream in which the stream elements are distanced from one another both transverse and parallel to the conveying direction (F).
