Abstract

A method of masking a surface comprising, providing a layer of ferromagnetic material beneath said surface and locating a mask formed from ferromagnetic material on the surface, wherein at least one of the mask or layer of ferromagnetic material is magnetised, so that the mask and layer are attracted together and the mask is caused to press substantially evenly upon the surface. The masking process is particularly appropriate when used with air brush techniques producing graphic designs and illustrations. Both the mask and the layer beneath the receiving surface can be laminated with ferromagnetic layers.

Description

SPECIFICATION A masking method and apparatus for use therein This invention relates to a masking method employing stencils, templates, masks, or the like for masking portions of a receptor surface to be treated with ink, paint or similar materials. The invention further relates to apparatus for use in such a method. The method and apparatus of the present invention is of particular use to persons employing air brush techniques to produce graphic designs and illustrations.
For such techniques to be effective, it is necessary for some form of mask to be used to ensure that the material being sprayed is confined to specific areas of the receptor surface being treated, and that no under spraying or bleeding of sprayed material onto the area intended to be masked, occurs.
It is also necessary to ensure that no movement of the mask with respect to the receptor surface occurs.
Currently, masks are formed from sheet material. such as plastics or cardboard. In use, such a mask is retained on a receptor surface to be treated by lengths of adhesive coated tape. The positioning of the adhesive tape so that a chosen mask is held to the receptor surface in such a way that, no under spraying or bleeding occurs and, areas of the receptor surface which it is desired to spray are not occluded, is a skilled and time consuming operation.
These known masking techniques have not proved satisfactory for the production of graphic designs and the like using air brush methods because, in practice, they often fail to inhibit under spraying and the bleeding of sprayed material onto areas intended to be masked.
It is an object of the present invention to provide a masking method in which magnetic properties are utilised in order to cause a mask, stencil, template or the like, herein referred to as a mask, to adhere to a receptor surface.
An additional object ofthe invention is the provision of apparatus with which to put the aforementioned method into effect.
According to a first aspect of the present invention there is provided a method of masking a surface comprising, providing a layer of ferromagnetic material beneath the surface and locating a mask formed from ferromagnetic material on the surface, wherein at least one of the mask or layer of ferromagnetic material is magnetised, so that the mask and layer are attracted together and the mask is caused to press substantially evenly upon the surface.
Advantages of the present invention include the elimination of any requirement for adhesive tape to be used to fix the mask to the receptor surface and, the inhibition of bleeding of sprayed material onto the area intended to be masked as a result of the even pressure exerted by the mask upon the surface.
In a second aspect of the present invention a mask for use in the method in accordance with the first aspect of the present invention is provided, which mask comprises a ferromagnetic material. In an embodiment the mask comprises a laminate of a sheet or layer of ferromagnetic material and a sheet or layer of absorbent material. Thus the mask may comprise a laminate of metal and an absorbent material such as art paper. An advantage of such embodiments is that the mask may be used with the layer of absorbent material or art paper in contact with the receptor surface, in order to further inhibit any bleeding of sprayed material between the mask and the receptor surface.
In further preferred embodiments the ferromagnetic component of the mask may be magnetised; the mask may comprise a thin layer of ferrous foil sandwiched between layers of art paper; or, the mask may comprise a thin card coated on one side with iron powder and sandwiched as before between layers of art paper.
Masks in accordance with the second aspect of the present invention should be employed on a receptor surface of an object having ferromagnetic properties, such as a motor car panel, or in conjunction with a ferromagnetic backing placed under the receptor surface, when the latter is provided on a nonferromagnetic object. The ferrormagentic component of the mask should be magnetised when the ferromagnetic material on the opposing side of the receptor surface is not magnetised.
In accordance with a third aspect of the present invention a board for use in the method of the first aspect of the present invention comprises a layer of magnetised material.
The board preferably includes a magnetised base layer comprising a multi polar singlefaced synthetic sheet bonded to a thin backing sheet to provide the necessary rigidity.
Such a base layer material is marketed under the trade name PLACAM. Alternatively, thin flexible magnetic PVC may be used in place of the synthetic sheet of PLACAM material.
In use in a method in accordance with the first aspect; when the receptor surface to be treated is provided on a sheet of non-ferromagnetic material, such as art board or paper, the sheet of non-ferromagnetic material is placed on the magnetised board and a mask in accordance with the second aspect of the invention is then placed on the receptor surface. The surface may then be sprayed.
In an alternative specific embodiment the mask comprises a laminate of magnetised plastics material sandwiched between a paper layer and a layer of synthetic plastics material.
Such a mask may be used directly on a receptor surface of a ferromagnetic object, such as the side of a vehicle.

Claims (10)

1-.
