Abstract
The present invention provides a method of shaping a sheet of polymeric film to substantially conform to a curved surface of a rigid substrate, such as a vehicle windscreen. The method includes the steps of: cutting the sheet of polymeric film to a size appropriate to the rigid substrate; positioning the sheet adjacent the substrate; and applying heat to the sheet of polymeric film using an infrared or radiative heat source such that said heat is substantially uniformly distributed over a portion of the sheet comprising an area of at least about 500 cm.sup.2 at any given time to shrink and/or stretch the sheet of film thereby causing the sheet to conform to the curvatures of the substrate. This step of applying heat is therefore typically performed In the absence of any forced air-flow. The invention furthermore provides a method of coating a curved surface of a rigid substrate, such as a vehicle windscreen with a sheet of polymeric film, including the steps of: shaping the sheet of polymeric film to substantially conform to the curved surface of the substrate as described above; and adhesively bonding the shaped sheet of polymeric film to the curved surface of the rigid substrate.
