BKlEF HISTORY
The IS0 Recommendation R 1019, Cinematography - - Dimensions ofdaylight loading spools for 16 mm

2. DIMENSIONS AND CHARACTERISTICS
2.1
The spindle and keyway holes shown in the Figure should be incorporated in both flanges* and should
be aligned. (Some laboratories use 35 mm rewind equipment for winding 16 mm film; often the
spindles on this equipment have long keys.) A second keyway, in the corner of the spindle hole
opposite the required keyway, is optional, but if used, should be incorporated in both flanges.
2.2
If rivet heads or other fastening devices extend beyond the outer surfaces of the flanges, they should
lie at a diameter larger than the minimum K diameter and should be within the boundaries defined by
oth
