For the sake of completeness, I'll explain how the gate tension adjustment works on Centurys, although, like Brad said, this won't help the problem described.Newer 35mm Centurys have flexible bands in the film trap; the gate presses the film against these bands and tension is set by adjusting the tension of the bands. This is set using a smallish knob (usually with a numbered scale) at the top of the trap. This is very similar to the same adjustment on a Simplex X-L or PR1014. Older Centurys (Cs and early SAs) don't have the flexible bands, but instead have _two_ adjustments on the gate itself, one each at the top and bottom of the gate. Older JJs don't have flexible bands either; the tension adjustment is a knob on the gate, to the left of the large knob that one uses to open the gate. This is the same location as the thumbscrew in 35mm Centurys that one unscrews to remove the gate for cleaning. I don't know about newer JJs; maybe someone else does.
