On Youtube, if you search for words like "theatre projector changeover" there are some great videos of projectionists showing how it's done.
Apparently there are "platter" systems that let you splice all the reels together and project the entire film through one lens with no changeovers, but my story took place at least 15 years ago, and it was not a very big or modern theatre.
