Welcome to BigScreenBiz.com

It has happened twice in the past 2 months. We have Christie 35 mm Projectors and Platters. And on the payout table, the film begins bubble, and moves. If left unattended a brain wrap occurs, and or the film ends up on the floor. WE have stoppers places around the film but still does not keep from bubble and brain wrap. We have had two prints to do this. We have moved it to different platters with no results.
Ever heard of this? Is if defective prints?

Thanks,

At the CineMark where I worked there was a similar problem. The booth tech said it was due to static electricity. A bucket, half filled with water, was placed under all 15 platter systems to add moisture to the air. It seemed to help. Although there was still some bubbling (depending on the season) there was no brain-wrapping from it. You might also try cleaning your platters regularly. This will help discharge the static electricity. Just about any household cleaner will do. At the last theatre I managed our service tech had me using one of those orange cleaners.

Just do not use Windex on those platters. There are many other threads on this subject. Do searches for static and humidity.

Re: the bubble... make sure your projetor isn't nicking the sprockets. That could cause what you're seeing.

I agree with the static theory. We have had similar environmental problems during this time of the year. BOth humidity and static can cause this problem. Make sure your climate in the projection booth is controlled for these.
