Abstract: An arrangement for closing bottles comprises a rotor arranged to move bottles over a partially circular path, a flanging device provided with a flanging element arranged to engage with lower edges of caps to be placed on the bottles, bottles gripping elements connected with the rotor and arranged to rotate the bottles about their own axes and also to disengage the bottle from the flanging element, the flanging element including a centrally arranged disc having a ringshaped part with a peripheral edge engageable with the cap, the disc having an axis which extends parallel and is eccentric relative to an axis of the rotor, and the disc being arranged so that the partially circular path of the bottles extends around the peripheral edge of the disc.
