Abstract: A placing arrangement for palletizing an advancing material web of, for instance, unvulcanized rubber, includes a height-adjustable guiding device which includes a placing frame, a carriage mounted on the placing frame for displacement in opposite directions, and at least two driven placing rollers that are rotatably mounted on the carriage and bound an action gap. A centering device is mounted on the guiding means upwardly of the placing rollers. The centering device is operative for guiding the material web so as to constantly remain in its central disposition. The centering device includes two guiding rollers which are situated oppositely to one another and extend transversely of the placing rollers. The guiding rollers are pressed in their position of use against respective lateral edges of the material web, and they are simultaneously moved together and apart to the same extent.
