Particle Transfer Roller : ウィキペディア英語版 | Particle Transfer Roller The Particle Transfer Roller, often abbreviated to PTR, is a device for cleaning motion picture film. It consists of a cylindrical roller coated with urethane, over which the surface of the film passes. ==History== The Particle Transfer Roller was developed by Eastman Kodak and launched in 1989. It was intended to replace the organic solvents that were the main method of film cleaning before that point.〔http://www.filmshooting.com/scripts/forum/viewtopic.php?f=1&t=13502〕 Although their effectiveness is not usually considered sufficient for lab operations, where ultrasonic cleaning with a solvent solution remains the standard, the PTR sold widely for use in projection booths and transfer houses.
