10.3 DOLLIES FOR CURVED SURFACES
Using a flat dolly on a curved surface can produce misleading results.
The gap between the flat and curved surfaces will not be filled by the
adhesive, resulting in one or more of the following effects:
Ÿ The dolly may peel or twist off instead of being pushed off.
Ÿ The surface area to which pressure is applied, will be modified.
This will lead to results from different curvatures not being
comparable.
Ÿ The amount of adhesive may not be sufficient to withstand the
exerted force, resulting in the adhesive breaking before the
coating separates from the substrate.
These difficulties are overcome by using curved dollies on diameters of
less than approximately 2m (6' 7"). An extensive range of curved
dollies is available.
Curved and flat dollies are all used in the same way, matching the
marks on the dollies with the longitudinal axis on the curved surface.
