I have a Rollex back for a KW Etui I just purcashed. The problem I have is this: when I am winding the film it reaches the point where the backing alone finishes and the film moves across the pressure plate and around the edge of the holder onto the take-up reel. It feels very tight, and I've torn the film twice loading it as the thickness of the tape + film + backing seems to be a real squeeze.

Once the film begins to move onto the take-up spool, that is, once the tape has passed over the edge of the plate, it's fine. It spools smoothly.

I'd rather not have to begin winding on with the back very slightly open [to give more clearance] and thus lose the first frame, or have to load it in a changing bag. Any suggestions for something I might be doing wrong, or tips on tweaking the back?
