Foreword
This revised standard adopts SMPTERP106.1994 Movies "In less than 0.9m/s (180ft/min) running 35mm film system
Sheet tension. "
This standard and SMPTERP106. differences in 1994 is as follows. according to GB/T 1.1-2000 made editorial changes.
The standard proposed by China Machinery Industry Federation.
This standard is under the jurisdiction of movies and audio-visual industry machinery Machinery Standardization Technical Committee.
This standard was drafted. Qinhuangdao Audio-Visual Machinery Research Institute.
The main drafters of this standard. Yanji Hua.
This standard is the first release.
Introduction
The machinery industry standard developed by the film and audio-visual machinery Standardization Technical Committee for the equipment manufacturer, to design and adjust new show
Or running 35mm film projection equipment and film take-up device to provide guidance. When the current movie and sprocket wheel combination, videos
Ultimate tensile fracture occurred before is 66.7N (15lbf). Therefore, all the take-up equipment must be kept in this film tension fracture limit tension
The few hundred or less. Film tension exceeds 4.4N (16ozf) will increase the wear and tear of the film, is not necessary. When the tension of 1.7N
(6ozf), the movie screen was enough to maintain stability.
35 m1 m1 Cinema System Specification film tension
1 Scope
1.1 standard specifies the 35mm movie film of less than 0.9m/s (3ft/s) speed run through the film transport system, in order to make the film loss
Injury to a minimum required film tension.
1.2 standard detection method recommended by the film tension.
2 Videos tension
Under normal conditions the sprocket, the film tension should be 1.7N ~ 4.4N (6ozf ~ 16ozf) between.
3 Detection
3.1 0.9m ~ 1.8m (3ft ~ 6ft) film wound on the film holder tablet cores, or take-in sheet supply system operates in normal mode
Case, dynamometer pull the film a measure. Tension shall be measured film winding diameter (die diameter) drawing tabulation, and
Comply with the provisions in Chapter 2.
3.2 In order to measure the tension of the film, a short film will be screened sheet is placed inside the door, the door closed sheet, with a dynamometer pull the film through the film gate.
NOTE. Adjust the film gate pressure, so that the screen is not more than beat 0.020mm.
