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 shapeable 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 strands, and the shaping rollers are mounted in lateral guide plates by means of quick-change apparatuses.
Device for the cross-sectional shaping of a plurality of plastics strands guided in parallel next to one another via at least one rotatable shaping roller (18), in which the shaping roller (18) is provided on its surface with a plurality of peripheral shaping depressions arranged in parallel, in which the cross section of the plastics strands can be shaped in accordance with the cross-sectional shape of the shaping depressions, the at least one shaping roller (18) having rotary couplings (34) on the front side for connection to supply and discharge lines (36) for a liquid medium through the shaping roller (18), and the shaping roller (18) being rotatably mounted on the end face in guide plates (10, 12) of a frame (1), characterized in that the at least one shaping roller (18) is mounted in the guide plates (10, 12) by means of a quick-change device (24, 35), in which the rotary couplings (34) are arranged on the end face so as to be central with respect to the quick-change devices (24, 35), and in that the shaping roller (18) can be removed from the frame (1) after separation of the connections (36) from the rotary couplings (34) and removal of the quick-change devices (24, 35).
