ABSTRACT OF THE DISCLOSURE A packing arrangement for sealing the outer surface of a rotary, drum-like object, such as a washer used in manufacturing cellulose, with a non-rotating annular packing, which is most advantageously composed of one or several side-by-side packing fillets, e.g. braided packings, said arrangement comprising a circular packing body which together with the rotating drum surface defines a space in which the packings have been installed. The drawback encountered in existing arrangements is wear of the packing, and consequent leakage. In the packing arrangement of the invention this has been solved in that the packing body is, at least in its radial direction, elastically supported so that as the drum- like object rotates the packings yield to the movements of the drum surface arising from radial displacements of the drum.
