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. The carriage device of the wrapping device is intended to carry along the film feeding device, and it includes several carriages placed one after the other and coupled to each other, wherein at least one the frame structure is placed or can be placed in one or more carriages.
