Clean your rollers?
It could be vignetting from a lens not having an image circle big enough for the amount of movement being used.

where is the straight black line? IF its on the tab end, in the picture area of the print then the envelope was not pushed in all the way into the cap

If it only happens when you use front swing, then I'd agree with Steve Simmons--you are probably exceeding the image circle of the lens. If it's a wide lens, this might be hard to see on the groundglass, and you'll just need to experiment to learn how much movement you can use with this particular lens.
Perhaps the bellows is blocking the light path.
Image circle limitations will *never* produce a sharp or straight edge; they'll always be a gradual fade with a circular arc. Much more likely is bellows vignetting, which (if close to the film) would produce a rather sharp edge and would almost always produce a straight edge.
