In a wrapping apparatus comprising a two-part endless track (12A, 12B) surrounding a wrapping station, a shuttle (13) for dispensing wrapping medium able to ride around the track and thereby wrap an article in said station, and a track support structure (16A, 16B) such that at least one part of the track may be moved relative to another part so as to open and close a gap between those parts, a shuttle change may be effected by providing a movable shuttle carrier (54) in the form of a length of track, and means enabling the shuttle carrier to be inserted into and removed from a gap in the track whereby a replacement shuttle may be driven from the carrier onto the track and a spent shuttle may be driven from the track onto the carrier for removable therewith.
