Abstract: A wrapping device having at least a circular track structure which forms a closed track, and a film feeding device which is arranged to circulate along the track and to feed a film around a piece to be wrapped, wherein the film feeding device is provided with a mechanism for fixing a film roll in the film feeding device in a rotating manner, feeding mechanism, through which the film is arranged to be fed at a predetermined film tension, and a drive mechanism which is arranged, if necessary, to rotate the film roll in a direction in which the film is rewound onto the film roll and which is arranged to receive its driving force by mechanical contact between the drive mechanism and the circular track structure. The film feeding device also has a mechanism which is arranged to disconnect and reconnect the contact, wherein the mechanism is controlled either on the basis of the film tension or on the basis of the location of the film feeding device on the track, or on the basis of them both.

Abstract: A wrapping device provides at least a circular track structure which forms a closed track, and a film feeding device which is arranged to circulate along the track and to feed a film around a piece to be wrapped. The film feeding device includes a frame structure with a rotatable film roll and a feeding mechanism through which the film is arranged to be fed at a desired film tension. The frame structure can be disconnected from and reconnected to the film feeding device for the change of the film roll, and for the change of the film roll, the wrapping device also includes an automatic change system for the change of the frame structure. The frame structure is an integrated unit which can be independently disconnected from and reconnected to the film feeding device.

Abstract: A wrapping device comprising at least a circular track structure which forms a closed track, and a film feeding device which is arranged to circulate along said track and to feed a film around a piece to be wrapped, wherein the film feeding device comprises a frame structure which is provided with at least means for fixing a film roll in said frame structure in a rotatable manner, and feeding means, through which the film is arranged to be fed at a desired film tension. Said frame structure can be disconnected from and reconnected to the film feeding device for the change of the film roll, and for the change of the film roll, the wrapping device also comprises an automatic change system for the change of said frame structure. Said frame structure is an integrated unit which can be independently disconnected from and reconnected to the film feeding device.
