The apparatus of claim 1, wherein said rotating support member (7) is capable of being rotated. 3. The apparatus according to any one of claims 1 or 2, wherein said rotating support member (7) has a cutter for cutting off the film strip (13) stored in the film storage device (11). 4. The apparatus according to any one of claims 1 to 3, wherein said rotating support member (7) has a welding device which is a means for welding one end of the film strip (13) stored in the film storage device (11). 5. The apparatus according to any one of claims 1 to 4, wherein said rotating support member (7) has an opener (15) for opening the film strip (13) or film strip having the form 6. The apparatus according to any one of claims 1 to 5, wherein said film apparatus (11) includes at least one driving element to cause the film (2) to move continuously transverse to the direction of covering (U) of said film. 7. The apparatus according to any one of claims 1 to 6, wherein the at least one driving element is capable of moving in a first direction transverse to the direction of covering (U) of said film (2) so as to store two first sections of partial film (24) arranged in opposite directions of film (2) that are continuously moved by the driving element in the film apparatus (11), wherein said driving element is capable of deflecting and can move in a second direction opposite to the first direction and transverse to the direction of covering (U) of said film (2), so as to store the additional section of partial film (24) that is continuously moved by the driving element. 8. The assembly of any one of claims 6 or 7, wherein said film assembly (11) has at least one continuous belt (19) and at least one driving element for handling film (2) fixed to said continuous belt (19) and causing film (2) to move continuously transversely to the wrapping direction (U) of said film while said continuous belt (19) is in motion. 9. The assembly of claim 8, wherein the at least one first driving element is located on the top surface of said continuous belt (19) and at least one second driving element is located on the bottom surface of said continuous belt (19), and when said continuous belt (19) is in motion, the first driving element for causing film (2) to move continuously in the wrapping direction (U) of said film is capable of moving to the right and the element For a second drive to cause the film (2) to move transversely to the direction of wrapping (U) of said film (2), it is also capable of moving to the left. 1 0. The assembly of claim 9, wherein the drive element, which is moved to the right, moves through a region around the first deflection roller (22) of the continuous belt (19) and is then intended to be moved to the left transversely to the direction of wrapping (U) of said film (2), and the drive element, which is moved to the left, moves through a region around the second deflection roller (22) of the continuous belt (19) and is then intended to be moved to the right transversely to the direction of wrapping (U) of said film (2). 1 1. The assembly according to any one of claims 8 to 10, wherein at least one guide roller (21), preferably one plurality of guide rollers (21) for said film (2), is located on the top surface of said continuous belt (19), and/or at least one guide roller (21), preferably one plurality of guide rollers (21) for said film (2), is located on the bottom surface of said continuous belt (19). 1 2. The machine set according to any one of claims 1 to 11, wherein said film feeding head (3) is capable of moving in the direction of wrapping (U) of said film (2) and in a direction opposite to the direction of wrapping (U) of said film (2). 1 3. A method of wrapping a stacked layer of object (1) with film (2) such that, for wrapping a stacked layer of object in a first set (1), in particular, a stacked layer of object (1) having a shape that is not Being square in shape and having dimensions L x W, film is fed from the base (6) of the film feed head (3), whereby a section of film (13) is released from the film (2) and this section of film (13) is drawn over the stack of objects in the first set (1) for subsequent wrapping of the stack of objects in the second set (1). In particular, the stack of objects (1), which is not square in shape and has dimensions W x L and is rotated at an angle of 90° with respect to the stack of objects in the first set, film (2) from the base (6) is fed to the film collection device (11) of the rotating support (7) of the film feed head (3) first, the section of film (13) prepared for at least one wrapping operation is stored in The film holding device (11) and the film section (13) are then released from the remaining film (2), and the rotating support member (7) is then rotated in such a manner relative to the base (6) in such a way that the film section (13) may be drawn down over the second set of object stacks (1), and the film section (13) is then released from the film holding device (11) and drawn up over the second set of object stacks (1). 4. The method of claim 13, wherein one end of the film range (13) stored in the film storage device (11) is welded while said rotating support member (7) is rotated. 5.
