Abstract
An electrostatic field is created across a layer of material which has been placed on a surface with an adhesive layer therebetween to force the layer of material toward the surface, compressing the adhesive therebetween. To carry out this process, various forms of apparatus are disclosed which provide a substantially consistent electrostatic field across a film of material and a coating of adhesive to a surface to which the material is to be secured.
