May 1947 A PROPOSED FlLM AND IDENTIFICATION BAND 475
I wish to extend thanks to the many individuals who have given their co-operation in developing this proposal.
DISCUSSION
DR. C. R. DAILY: I should like to know whether this band has been given an exchange trial yet.
MR. SCHWARTZ: No, but I have given it an exhaustive test at the studio. Various questions were raised as to the possibility of the tongue becoming worn or torn, and the question of the operator tearing off the ends. So far as the operator is concerned, I have no answer. So far as the wear and tear of the film is concerned, I did allow the film to flap on a metal bench 1500 or 2000 times, which was an even more drastic test than the usual flapping of the film in the lower magazine of the projector or in the rewind box in the booth. I cannot give any particular reason why the film stood up to wear and tear, except the fact that there was a lesser film surface concerned in threading and rewinding the film in the tests that I made. I placed the tongue into the slot on the reel as far as it would go, and then by exerting extreme pressure I pulled the film in such a fashion that normally the film would tear. To my surprise, it did not. To make the comparative test, I used the normal full width leader under the same circumstances and after the thirty-fourth time the film did tear.
MR. E. DENNISON: I have done a lot of research on handling film in exchanges for a period of twenty years, and I have also had many ideas as to how to keep the ordinary paper film band from being a nuisance to the operators and inspectors in exchanges. I think your idea of the lock is very good, but I think you are going to have the same human element to contend with as you had with the film. Several things have been evolved in the past years. One was the steel band. Some others had ideas of getting away from the ordinary paper band with the string and the button on it. I think you are going to have to educate every individual projectionist in the United States to use something different.
MR. SCHWARTZ: We know that from time to time we have damaged film come back because the operator just got mad. He could not get the film into the slot, so he tore another piece and another piece, and he had no concern about the film itself. I do think if we help him with the film lock, or some other method that may be adopted, he will feel we are with him and trying to help him in some way. The present method has been a drawback in many, many ways. More often than not the operator will take all the bands off of the reel and stick them down in the side of the container and just forget them. This proposal is an attempt to improve the method of identifying film, and holding the film from unraveling, so perhaps some method can be found whereby we can help to educate the operator to be a little more concerned about the film. If we are helping him, I am sure he will help us.
