A coiler can handling apparatus includes a platform rotatable about a substantially vertical platform axis for rotating a coiler can standing thereon; a travelling coiler can exchanger for moving a coiler can onto and moving a coiler can off the platform; and a centering device for centering a coiler can on the platform relative to the platform axis. The centering device includes first, second and third support rollers for engaging a lateral surface of the coiler can supported upright on the platform. The first, second and third support rollers lie on a common imaginary cylinder having a cylinder axis. The centering device further has a positioning arrangement for holding the first, second and third support rollers at the platform, apart from the travelling coiler can exchanger, whereby the coiler can exchanger travels without carrying therewith the first, second and third support rollers. The positioning arrangement includes a joint for movably holding the first and second support rollers to allow them to assume an inwardly pivoted position and an outwardly pivoted position. In the inwardly pivoted position the cylinder axis of the imaginary cylinder coincides with the platform axis.
