A quick release mechanism for a roller (6, 7) wherein the roller (6, 7) is mounted in a frame and rotationally driven (for example, a roller (6, 7) carrying a roll of stretch wrapping film (4) in a stretch wrapping head (1)). The quick release mechanism includes a pair of stub axles (22, 43) which support either end of the roller (6, 7) in the frame. One of the stub axles (22) are fixed within the frame and driven by a motor (8). The connection between this driven stub axle (22) and the roller (6, 7) ensures that no relative rotational movement occurs. The other stub axle (43) is "lockable" in a hole in the frame but is removable therefrom. The connection between the removable stub axle (43) and the roller (6, 7) allows free relative rotational movement. Withdrawal of the removable stub axle (43) from the frame allows the roller (6, 7) to be disconnected from its connection with the driven stub axle (22) and removed from the frame. Refitting of the roller (6, 7) is simply a reversal of this process.
