Full-width film-supporting, driving, and stripping arrangement for motion picture film printing machines

摘要: The present invention replaces the film supporting and stripping arrangement in most widely-used conventional motion picture printing machine with a driving sprocket combined drum which drive fully support both superimposed negative copy throughout their entire widths prevents them from moving apart one another as they pass through exposure zone wherein light passes two films but not beyond obstructs further passage of so that it is either reflected or deflected backward drum. While are passing zone, driven by single toothed maintains synchronism while supports width thus intermittent separation occurring machines supported only at opposite edges, consequently lack sharp definition caused such separation.
