ABSTRACT:
A method for forming mirror assemblies, especially rearview mirror assemblies for vehicles, wherein a thermoplastic mirror case is held inverted with its side wall portions extending downwardly. The side wall portions are softened by immersion in a heated bath and are pressed into a forming die which supports a reflective mirror element to form an arcuate mirror element retaining lip about the peripheral edges of the mirror element. Apparatus for performing the method includes an indexing table which sequentially moves the cases and mirror elements loaded thereon to one position, removes the cases from the table, combines them with the mirror elements via the forming die, and returns the completed assemblies to the table.
