Film for masking aircraft components and method of positioning same
The invention solves the problem of protecting aircraft components during finishing. Such components are large and require masking films of vast dimensions which are difficult to handle and position rapidly. The invention relates to films packaged to facilitate transport, and to a method of positioning the packaged films on the corresponding components. The longitudinal and/or transverse portions of the films are packaged by means of at least one opération chosen from among: accordion folding, telescopic folding, gâte folding, roll folding, winding around a mandrel, and winding on itself. The packaged films can have positioning markers on at least one surface and/or tear lines suitable for detaching the portions of film to be separated. The invention also concerns a kit comprising a film and a guide element for guiding the positioning of the film on the component.
1. A packaged film for masking an aircraft fuselage, the packaged film being configured to cover said aircraft fuselage when unpackaged, wherein the packaged film is formed by:
performing a longitudinal accordion folding operation on a longitudinal portion of a film to provide a longitudinally stacked film;
performing at least a first transverse accordion folding operation on a first portion of the longitudinally stacked film to provide an intermediate folded film having at least a first sub-fold; and
performing a gate folding operation on the intermediate folded film to provide the packaged film;
the packaged film being configured to be unfolded in a reverse order of the longitudinal accordion folding operation, the at least a first transverse accordion folding operation and the gate folding operation to cover said aircraft fuselage,
wherein the packaged film has an inner face and an outer face, the packaged film comprising positioning marks on at least one face of the packaged film, said positioning marks being positioned on said at least one face according to geometric features of said aircraft fuselage to guide a positioning of the packaged film when unpackaged.
2. The packaged film as claimed in claim 1 , said positioning marks positioned on said at least one face according to geometric features of said component indicating an orientation of the aircraft fuselage.
3. The packaged film as claimed in claim 1 , said positioning marks including a tape selected from the following: a colored tape, a printed tape, a translucent tape, wherein the tape comprises perforated dots forming a tear line suitable for forming detachable segments of film.
4. The packaged film as claimed in claim 1 , the packaged film having an anti-static property.
5. The packaged film as claimed in claim 1 , the packaged film being permeable to air and solvent vapors.
6. The packaged film as claimed in claim 1 , the packaged film being impermeable to paint, water and solvents.
7. The packaged film as claimed in claim 1 , the packaged film having properties enabling coatings to adhere to the packaged film.
8. The packaged film as claimed in claim 1 , the packaged film being transparent.
9. The packaged film as claimed in claim 1 , wherein the packaged film is formed by performing a second transverse accordion folding operation on a second portion of the longitudinally stacked film to form a second sub-fold of the intermediate folded film, wherein the gate folding operation comprises folding the first and second sub-folds onto each other.
