An arrangement for the automatically releasable mounting of reels on rotatable hubs including an equidistant arrangement of several spring-mounted gripping levers on the periphery of a take-up drum, the external diameter of which corresponds to the borehole diameter of the reel, and in which the gripping levers extend parallel to the axis of rotation of the take-up drum: two spring arrangements close to each extremity of each gripping lever are prestressed radially in outward direction, each lever being approximately in the center rotatably supported by an adjusting screw in such a manner that on mounting of the reel, the end of the gripping lever which is nearest to the reel is travelled over first, and upon pushing the reel further on, the second end is travelled over, whereupon the first end is tilted upwardly into engagement with a locking surface of the reel.
