Not sure if this is where I should ask this question, but does anyone know why the platter system was taken up as ( in my humble oppinion )
the transport system in just about every cinema going. What was/is
wrong with towers?.
Also, anyone out there working with Cinemecannica projectors & platters,I would value some of your comments.

I don't know much about towers, but don't you have to rewind the film after each showing?

AFAIK, the need to rewind after each show with towers is the primary reason platters "won" the battle of automation. A well-designed tower (reel) system can certainly rewind the show quickly, while controlling torque, film tension, and accelerations to minimize the risk of film damage. Large reels got an undeserved bad reputation with "home brew" reel arms and rewinds that damaged the film with poor tension control and rapid accelerations. Likewise, the systems that attempted to automatically rewind the film backwards through the projector gate gave large reel automation a bad rap.Well-designed and properly maintained platter systems or tower systems can both be used with low risk of film damage.
