If so, how can the dark band be a light leak ???

The dark band is the area not struck by the light leak, i.e., the only correctly exposed part. The lighter areas next to the dark band were hit extraneous light and the exposure tapers off moving from left-to-right.

Best,

I agree with Doremus's idea.

The dark band is just the shadow of the film holder (the fogging light is blocked).

What Doremus said. Check to see that that particular holder is seating properly when you slide it into the back of the camera. This happened to me with my Canham and the 4x5 reducer and 545 folder. A small screw on the reducer was preventing the 545 holder from seating properly.

Thanks a lot for the help so far. I just shot some more photos yesterday and I put the focusing cloth over the filmholder during the exposure and while pulling and putting back the darkslide. Now everything is fine and I know, that it's a light leek. I was using a 10 stop ND filter on the ones that had the lightleek. So I will watch it carefully when I pull and insert the darkslide again. I will see if it was my falt or a lightleek in the system in the next trys. But thanks a lot for the feedback. It helped a lot!!
