The object is applied to the glass surface by a platen assembly mounted inside the apparatus which resiliently urges the object against the glass surface. In one embodiment, the platen assembly is mounted on a resilient diaphragm within the apparatus and the application of a vacuum causes the diaphragm to move the platen assembly towards the object, thereby causing the platen assembly to urge the object against the glass surface. In a second embodiment, the platen assembly is mounted to the apparatus shell or housing and the apparatus is sealed against the glass surface by a resilient bellows. Upon application of a vacuum, the bellows compresses, thereby causing the platen assembly to urge the object against the glass surface. |
