Surface between intersecting curves

Hello everyone,

first of all, sorry for my bad english :D

I have a problem, maybe many. After edge bundling I have many curves. They doesn't match exactly and so on. See example picture.

I need surfaces between the curves. What will be the best solution to go on?

Should i "slice" a surface with the curves or is there a way to create surfaces between the lines ?

Sorry, but I have no idea. If somebody can help, I would be very thankful. 

Best regards,

Tim
