Help with paper roll animation

Hello Everyone,

I have been trying to create an animation for my portfolio site where a roll of paper un ravels to reveal it’s content. I have most of it done but I’m having a trouble getting the textures on the back of the sheet to move in a way where it look like the paper roll is actually rotating instead of a straight bar moving accross the screen.

Here is a link to the code pen:

Any help would be greatly appreciated.

BR,

Jonathan
