The present invention concerns the deposition of fluorine modified, titanium dioxide films (TiO2) onto hot glass by atmospheric pressure chemical vapor deposition (APCVD) using TiCl4 vapor. The invention is also suitable for depositing other metallic oxide films from their metallic halides such as SnCl4, GeCl4, and VCl4. The present invention provides a process that deposits a novel, fluorine modified, titanium dioxide film (TiO2) onto hot glass by atmospheric pressure chemical vapor deposition using TiCl4 vapor.

An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450% greater than its initial, pre-stretched length. The increased contact between the large diameter heated rolls and the film and the short draw gap between the two heated rolls result in a highly stretched film having minimal neck-in.
