Definitions
- the present invention relates to a stencil to protect the surface surrounding an area being abraded, for example in the vehicle refinishing trade.
- a high spot as previously mentioned may be removed by selecting a stencil with a suitable size and shape of hole, placing this hole over the high spot (the stencil maybe taped into position or hand-held against the surface to be worked on), so that the high spot is exposed and then slicing the excess material with a very sharp blade eg a one sided razor blade over the stencil held at near to horizontal to the stencil, before abrading either by hand with an abrasive wrapped around a suitable sanding block, or by means of a sanding machine.
- a very sharp blade eg a one sided razor blade
- the material within the selected hole in the stencil will stand as high as the thickness of the stencil, if a hard block or backing plate is employed, which may then be finished with a fine abrasive once the stencil has been removed, so minimising risk of damage to the surrounding surface.
- the area inside the stencil shape will be abraded and can be feathered by placing successively larger sized shapes over the repair spot and abrading with successively finer abrasives.
- Masking stencils US6099388 and US5399421 are cited as they perform the function of protecting the surrounding area while an abrasive process is carried out.
- the key difference is that the current application is designed for protection of a surface on which undesired high spots need to be eliminated by abrasion and to a precision that is as close as possible to the surface surrounding the high spot, including the exposed area inside the stencil hole, without causing damage to it.
- the current application is not intended to eliminate low spots.
- mask 20 would resist an abrasive being passed across its surface nor is it designed to be as thin as practically possible and so would not permit the abrasion of a high spot to near flush with the surface.
- US 6099388 shows a protective mask whose characteristics are:
- Abrasion is carried out "with radial strokes relative to the compact disc" column 7, line 30"the radial strokes extending from side to side IN the localised area” column 7, lines 31 and 32. Also if the hole to localise the "area is cut in the mask" column 7 line 3, this suggests that the material is not sufficiently resistant to withstand sanding with a mechanical sander. If the hole were cut by a mechanical method eg scissors or a sharp knife, this would lead to burring or at least an inexact edge which would result in the stencil not lying perfectly flat on the surface, if the mask were made of a sufficiently resistant material. If the mask did lie flat after manually cutting a hole, this would suggest that the material would not be resistant enough to serve the purpose of the current invention.
- patent US5399421 designed to abrade undesired high spots to a level near flush with the surface, but rather to protect the surrounding area only outside the stencil hole while the abrasive process removes material from the surface to a level lower than the remaining surface.
- FIG 1 shows a top view of the stencil (1), manufactured from 0.05mm to 0.03mm hard quality stainless steel shim in a sheet measuring 12cm by 12cm, with holes (2) designed to expose typical spot repairs, namely lacquer runs, imperfections and paint-filled chips or scratches, and created by a process to ensure that edges are flush with stencil body, for example an etching process.
- the etched holes are calculated to be of a dimension that will not allow the abrasive block, sanding machine pad or blade, when held horizontal to the surface, to make contact with the surface to be protected at any point, ie the dimensions of the holes are too small to allow the sanding block, machine pad or blade to fit completely inside.
- the stainless steel employed to make the stencil offers high durability to the abrasion process so that the surface to be protected is so, prevents the stencil from oxidation, which would affect its uniform positioning on the surface, and allows the stencil to be re-used.
