Abstract
A plastic annular disk has a convex exterior surface upon which is situated an adhesive wafer. A removable protective shield is formed to have a substantially wrinkle-free surface with a contour identical to that of the convex surface. The disk and wafer are placed in a vacuum chamber, below a planar plastic sheet. The top of the chamber is heated. The space above the sheet is evacuated to draw the sheet against the heated surface. The remaining portion of the chamber is then evacuated to eliminate air between the wafer and disk. Lastly, the top of the chamber is vented such that the heated sheet is pressed over the wafer and disk.
