Lights break out the frame margin of a photograph when bright scene (e.g. sky...) is taken and expose the next cut of film. I tried to tightened up bolts and filled up any possible gap in the camera, but it does not work.
Please suggest me another possible causes of breaking out of the light and way to fix it....

You don't state which Rolleiflex model.

Is the pressure plate set to 120? The 135 setting (for 35mm film) would hold the thinner 120 film less rigidly against the film gate.

Rolleiflex 3.5F.
Yes, I set the pressure plate to 120.

Thank you for your concerns...

This could also be related to the film used.... the film has an anti-halation coating on the back surface to prevent light from bleeding out beyond the exposed area; some might be more effective than others.

I've seen this effect on my Rolleiflexes (3.5B and 2.8C) too. This often happens in daylight shots when the sun is near the edges of the frame or in night photographs with street lamps. Usually it doesn't protrude into the next frame, so it never really bothered me.

As already mentioned, it's either the pressure plate or the film's backing paper reflecting back into the film, which probably varies with manufacturer.

There have been discussions of this problem on the various Rollei user groups. Some people think that it's a definite design fault. Is the exposed area on the next frame in a narrow band? This seems to be the most common problem and is supposed to be caused by light bouncing off the chrome film rollers. I've seen this effect in a 2.8C and a 3.5E - it only occurs when photographing a very bright scene.

Cheers
