Tape roll-off animation around a corner

Hi there,
I’d like to animate a roll of tape being rolled off (with a spiral) around a corner. The rolling off just with the spiral works fine, but as soon as i try to rotate - or “go” around the corner it doesn’t work.
Does anybody know how to do this? I’m not very familiar with constraints and so on…

I hope the sceenshot explains what I want to do.
