Wrapping apparatus for winding a wrapping foil web (F) around an object (1) includes a foil dispenser (2) arranged to circulate along a ring-like endless track (3) around the object to be packaged. The foil dispenser (2) comprises a frame (4), a detachable and replaceable foil roll (5) mounted on the frame, supporting elements (6) for supporting the foil roll on the frame, and tensioning arrangements (7) for braking foil delivery from the roll and maintaining a predetermined foil tension. The tensioning arrangements (7) comprise a sensor (8) for detecting foil web tension, and an electric motor (9) for driving the foil roll (5). The torque, speed of rotation and direction of rotation of the electric motor is controlled on the basis of foil tension as detected by the sensor.
