Abstract

Figures 1 and 2 illustrate two flexible sheets (1 and 2) for use in a spot paint repair on the metallic surface (3) of an automobile body panel (4). The two sheets (1, 2) form part of a set of three sheets. Each sheet of the set possesses magnetic properties. It is wholly magnetic and is of rubberised isotropic material. The outer surface of each sheet has a non-stick coating of PVC (polyvinyl chloride) or other material that allows any paint adhering thereto to be wiped away. Each sheet of the set is of rectangular outline. Sheet (1) defines a relatively small circular aperture (5) disposed at the centre of the sheet. Sheet (2) defines a central aperture (6) of larger diameter. The other sheet of the set defines an even larger diameter aperture. To effect the spot repair, flexible sheet (1) is placed in position so that it magnetically adheres to the metallic surface (3) and so that the aperture (5) encloses the area to be painted. Suitable paint is then sprayed through the aperture (5) onto the metallic surface (3), the aperture acting as a window and the rest of the sheet as a mask. If feathering is required, flexible sheet (1) is removed and replaced by flexible sheet (2), so that its central aperture (6) covers the area previously painted. Feathering then takes place, using the aperture (6). The set may also be used for applying pre-paint abrasive and post-paint polishing material to the metallic surface (3).

Description

APPLYING PAINT TO METALLIC SURFACES
BACKGROUND To THE INVENTION
This invention relates to apparatus for, and methods of, applying paint to metallic surfaces, and to surfaces adjacent to metallic surfaces.
As used herein, the term 'metallic surfaces' applies to surfaces of magnetic-attractable material such as mild steel, and the term 'paint' to all forms of coatings applicable to a surface. Such coatings may include abrasive and polishing materials. The metallic surfaces may already carry a paint coating prior to use of the invention.
Various aspects of the invention relate particularly, but not exclusively, to the repair of metal panels used by automobiles.
SUMMARIES OF THE INVENTION
According to one aspect of the present invention, apparatus for use in applying paint to a metallic surface comprises at least one piece of flexible sheet material possessing magnetic properties so that it is magnetically adherable to the metallic surface.
The flexible sheet may define an aperture through which paint may be applied to the metallic surface.
The aperture may be round, or elongated for scratch repairs. When the aperture is elongated it is preferably of elliptical outline, but could be in the form of a slot.
Alternatively, the flexible sheet may be of tape form and thus usable as masking tape so as to enclose an area of the metallic surface. Preferably, the flexible sheet is wholly magnetic, in which case it is preferably of rubberised isotropic material. Such material generally incorporates a ferrite material.
Alternatively, the flexible sheet may be given magnetic properties by incorporating discrete magnets.
The flexible sheet material preferably has a non-stick coating that allows paint adhering thereto to be wiped away. The coating may comprise PVC (poly vinyl chloride) .
The invention according to a second aspect comprises a method of applying paint to a metallic surface, comprising the steps of taking at least one piece of flexible sheet material which possesses magnetic properties and magnetically adhering it in place on the metallic surface so as to enclose an area to be painted, and then applying paint to said area.
The paint is applied to said area preferably by spraying.
The invention also comprises a metallic surface with paint applied thereto according to said method, and further comprises a structure, such as an automobile incorporating said metallic surface.
According to a third aspect of the invention during a spray painting process a paint masking sheet is held in position on or adjacent to a metallic surface by the magnetic attraction between a magnetic holding means and the metallic surface.
The magnetic holding means preferably comprises a strip of a flexible magnetic material which preferably is attached to the paint masking sheet by a suitable adhesive. In general the sheet can be used on numerous occasions before it needs to be replaced.
Such an assembly of masking sheet and magnetic holding means can be used to protect surfaces which are in the neighbourhood of other surfaces which are being painted.
Alternatively such an assembly may be used to define a borderline to a surface area being painted.
Since the magnetic holding means can be used over and over again, the need for disposal of adhesive masking tape can be largely circumvented.
According to a fourth aspect of the invention we provide a strip of flexible magnetic material one side of which is coated with an adhesive for attaching the strip to a paint masking sheet, such as Tyvek®1422a paint masking strip.
According to a fifth aspect of the invention a paint masking sheet structure comprises a paint masking sheet having a pair of substantially parallel edges, strips of a flexible magnetic sheet material being secured to the sheet so as to extend along the respective edges.
Such a sheet structure can be used to cover up a surface which is adjacent to a surface being painted, and if desired, the edge of the masking sheet and/or an edge of the associate magnetic strip can define a borderline to the area being painted.
DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS
The various aspects of the invention will now be described by way of example only, with reference to the accompanying drawings, wherein: Figures 1 and 2 are front views of flexible sheet material, used for a first process;
Figures 3 and 4 are front views of flexible sheet material, used for a second process;
Figure 5 is a front view of an alternative form of flexible sheet material;
Figure 6 is a front view illustrating a modification; and
Figure 7 is a perspective view of a masking sheet structure.
Figures 1 and 2 illustrate two flexible sheets 1 and 2 for use in a spot repair on the metallic surface 3 of an automobile body panel 4. The two sheets 1, 2 form part of a set of three sheets.
Each sheet of the set possesses magnetic properties. It is wholly magnetic and is of rubberised isotropic material, obtainable from Anchor Magnets Limited of Sheffield, England. The outer surface of each sheet, that is the surface visible in Figures 1 and 2, has a non-stick coating of PVC (polyvinyl chloride) or other material that allows any paint adhering thereto to be wiped away. The thickness of each sheet is typically about 0.5 mm.
Each sheet of the set is of rectangular outline. Sheet 1 defines a relatively small circular aperture 5 disposed at the centre of the sheet. Sheet 2 defines a central aperture 6 of larger diameter.
To effect the spot repair, flexible sheet 1 is placed in position so that it magnetically adheres to the metallic surface 3 and so that the aperture 5 encloses the area to be painted. Suitable paint is then sprayed through the aperture 5 on to the metallic surface 3, the aperture acting as a 'window' and the rest of the sheet as a mask.
If 'feathering' (blending) is required, flexible sheet 1 is removed and replaced by flexible sheet 2, so that its central aperture 6 covers the area previously painted. Feathering then takes place, using the aperture 6.
For larger spot repairs, the third flexible sheet of the set may be used. Details of all three pieces are as follows:
Piece 1 Flat Magnetic Sheet 20 cm x 20 cm with a 9 cm diameter hole in the centre of the sheet. (Figure 1)
Piece 2 Flat Magnetic Sheet 22 cm x 22 cm with an 11 cm diameter hole in the centre of the sheet. (Figure 2)
Piece 3 Flat Magnetic Sheet 24 cm x 24 cm with a 15 cm diameter hole in the centre of the sheet. (Not illustrated)
Figures 3 and 4 illustrate two flexible sheets 10, 11 for use in scratch repair on the metallic surface 3 of the automobile body panel 4. The two sheets 10, 11 form part of a set of three sheets.
Each sheet of the set is wholly magnetic and of rubberised isotropic material. Each sheet is of rectangular outline. Sheet 10 defines a central hole 12 of elliptical outline and of relatively small cross-sectional area, which acts as a window, the rest of the sheet acting as a mask.
Sheet 11 defines a central hole 13 of elliptical outline and of relatively larger cross-section area, and is used for feathering purposes. Details of all three pieces of the set are as follows :-
Piece 1 Flat magnetic sheet 16 cm x 22 cm with an elliptical hole 6 cm x 12 cm in the centre. (Figure 3).
Piece 2 Flat magnetic sheet 18 cm x 24 cm with an elliptical hole 7 cm x 15 cm in the centre. (Figure 4).
Piece 3 Flat magnetic sheet 20 cm x 26 cm with an elliptical hole 11 cm x 18 cm in the centre. (Not illustrated) .
The pieces of each set can vary in external outline. For example, they may be circular, square or oval, or a set may comprise a mixture of outlines.
For larger repairs on body panels, a flat magnetic sheet 35 cm x 35 cm with a 15 cm diameter hole at the centre may be used with advantage.
The window apertures 5 and/or 6 define an exposed area through which abrasive materials may be applied to prepare the area ready for primer or paint repair, whilst at the same time protecting the surrounding undamaged bodywork from possible damage.
Following paintwork repair, the same window aperture(s) may be used to contain the painted area in order that cutting compounds or polishing materials can be applied within the apertures so as to polish out the repaired paintwork, containing the repair within the window area, and protecting the surrounding undamaged paintwork from damage or contamination. Figure 5 illustrates a modification employing flexible magnetic sheets 15 of rubberised isotropic material provided in tape form. The sheets 15 are employed as masking tapes, to enclose an area 16 of the metallic surface 3 of the body panel 4.
A flexible sheet need not be wholly magnetic, although this is the preferred form.
In Figure 6 a sheet 20 is shown, which is of similar form to sheet 10 of Figure 3, but is not wholly magnetic. Instead it is of non-magnetic rubberised material, and is given magnetic properties by incorporating discrete magnets 21, 22 of small (say 1.0 mm) thickness. The magnets 21, 22 are of rectangular 'picture frame' outline and are incorporated in the sheet 20 in such a way as to be flush with the inner surface of the sheet. The sheet 20 has a central aperture 23 of slot form, with magnet 21 surrounding the aperture in close proximity therewith. Magnet 22 is disposed around the periphery of the sheet 20.
All of the sheets disclosed herein have outer surfaces coated with nonstick PVC.
The invention enables repairs to be speeded up, reducing time currently spent in preparing, masking, (with adhesive tape) and cleaning up.
It will also be appreciated that the sheets of the invention are re-usable.
With reference to Figure 7 a masking sheet structure 30 comprises a rectangular sheet 31 of a suitable lint-free masking fabric, such as a sheet of Tyvek® 1422a material, paper or polyurethane. Opposite side edges 35, 36 of the sheet 31 are provided with strips 32, 33 and 34 of about 6 cm width of a flexible magnetic material such as a ferrite-filled rubber material.
Side edge 35 is provided with strips 32, 33 adhesively secured to opposite faces of the sheet 31, to enable either side of the sheet 31 to be placed in contact with an article being painted.
The strip 34 on the opposite edge 36 can be positioned as shown, or the sheet can be folded over such that the strip 34 faces the opposite way. Thus it is possible to reverse the sheet 31 if desired so that the outer face of the sheet 31 is made the inner face.
Furthermore, when the strip 34 has been folded over then a rounded corner of the fabric wrapped around the strip 34 can be used to define the border of an area of the articles being painted, thereby to provide a soft edge to the painted area.
The sheet structure 30 allows for very accurate and quick masking from the one side, but also allows the structure to be held firm against the repair panel to avoid any lifting or movement which can be caused from the airflow once the spray gun is introduced.
The double magnetic tapes 32, 33 also means that the masking sheet is both reusable job after job, and once the one side of the masking sheet 31 is contaminated with overspray, the user simply reverses the sheet and starts again with the clean side exposed using the reversed magnetic tape, whilst the existing tape 34 on side one will still act as a holding down feature to allow panel contact to hold the piece firm. This reusable and reversible aspect reduces by up to 40/50 times the scrap waste of the existing masking methods and provide a very fast and accurate method of masking areas to be painted.
A second consideration and an important aspect of this design is that by using magnetic tapes attached to fabric we are able to get exact and accurate straight edge masking when repainting objects such as car bonnets (hoods) , boots ( hoods) and down door area or across roof and provides accuracy for swage lines. This provides savings of up to 80% of time against the existing methods.
A third feature of the structure of Figure 7 is that the straight edge of the tapes can also be inserted into the car edge joints to provide an immediate straight and soft edge to paint up to which again is held firmly in place by the magnetic process.
A fourth feature of the process is that using the magnetic tape as the holding process we are able to completely follow the contours and shapes of the body panels.
The fifth consideration and which also increased the time in which painting jobs are completed is that the magnetic hold down of the masking materials ensure that there is no contamination from the tape adhesives which can often be the case with existing adhesive tapes, or the baking on of masking tape in hot weather conditions making it very difficult and labour intensive to remove.
Finally, the straight edge accuracy already discussed can make for very fast and accurate lining when wishing to introduce a colour change line onto the panels, truck cabins, or bodies, by simply placing two such masking sheet structures to the line width, then simply applying the paint between the two straight edges, which will not lift, and in addition, will be held firm by the second magnetic tape holding the piece in position.
We also propose a magnetic colour matching swatch which can be similar to the mask of Figure 1 in appearance, but the dimensions are typically 14 cm x 9 cm with a central hole of diameter 4 cm. The swatch sheet is made of a similar material to that of the mask of Figure 1 , but the outside surface is provided with a white matt vinyl coating. Paint can be applied to the white surface of the colour swatch prior to a paint repair being carried out. The coloured swatch is then affixed to the car panel by its magnetic attraction, thereby allowing the paint colour mix on the swatch to be checked, from every light angle, that the colour mix matches the surrounding panel colour.
The paint can readily be removed from the vinyl to enable the swatch to be reused over and over again.
Instead of a white outer surface to the swatch, black and white stripes may be employed. The stripes enable the covering power of the paint to be assessed prior to the repair being undertaken.
