Zusammenfassung:	The invention relates to an apparatus for cross-sectionally shaping a multiplicity of plastics strands guided in parallel alongside one another over at least one rotatable shaping roller (18, 19, 20), in which the shaping roller is provided on its surface with a plurality of encircling shaping recesses which are arranged in parallel and in which the cross section of the plastics strands is shapable in accordance with the cross-sectional shape of the shaping recesses, wherein preferably three shaping rollers (18, 19, 20) of the same type for sequentially shaping the plastics strands are arranged transversely to the running path of the plastics strands, wherein the plastics strands are guided between a pair of two successive shaping rollers (19, 20) on a first side of the plastics strands and a third shaping roller (18), which is arranged, between the first (19) and second shaping roller (20) of the pair of shaping rollers, on the second side of the plastics strands in the running direction of the plastics stra
