Abstract
In the non-mechanical printing art relating to equipment for reproducing a negative on a photoelectric data carrier, a mechanical device for readily detachably applying a negative to a cylinder in such a manner as to assure flush application of the negative to the cylinder and proper positioning of the negative. The negative is provided with a spring contact strip at the leading edge and a knob contact strip at the trailing edge. The film is wrapped around the cylinder such that springs on the spring contact strip are caused to snap over knobs on the knob contact strip causing a tight wrapping of the film about the cylinder.
