Abstract
An expanding mandrel is useable for rotatably mounting a strip of material that is wound around a sleeve or core. The expanding mandrel includes an ejecting device that is useable to strip the sleeve or core from the mandrel. The ejecting device includes at least a first part, which is rotatable about an axis together with the sleeve or core, and a non-rotatably mounted second part. The first part can strip the sleeve or core from the mandrel by actuation of the second part. That second part is a piston which can be driven by a fluid under pressure.
