Abstract (en)
[origin: US2008258000A1] The invention relates to a method of releasing a reel awe, which is hydraulically restrained by a self-locking effect by means of inwardly located wedge surfaces of expansion elements. Removal of a coil from a reel awe is achieved, without problems, by lifting off the self-locking effect of the expansion elements at least partially or completely by applying longitudinal vibrations acting in an axial direction. The invention also relates to a correspondingly formed device.
