An arrangement for handling cylindrical bodies provided with central holes, the apparatus comprising gripping arms provided with gripping pins, second means arranged to move the gripping arms to obtain a forward movement, third means arranged to wind the gripping arms clockwise and counterclockwise, and fourth means arranged to move the gripping arms towards each other such that the gripping pins are self-centeringly brought into alignment with the central holes of the cylindrical body and to make a reverse movement of release. To provide an arrangement operating with high speed, the second means by which the forward movement of the gripping arms is obtained and/or the third means by which the winding movement of the gripping arms is obtained are formed as an elastic structure in a predetermined area such that the gripping arms are capable of adapting, during the grip movement and movement of release, to the displacements of position within this area, the displacements being determined by the position of the body or the position of the stand carrying the body.
