I have super struggled with this model and rigging for a month without weekend. I made this rigging object combining copy rotation + transformation. Because I thought some hinges should go faster than others to keep them stick together.

But as you can see in this file above,it does not work. The centre fall apart during the animation. How I can make them get together during the animation? enter image description here

    $\begingroup$ I don't know much about animation or rigging, but I don't really understand the problem. Could you please describe the issue more in-depth? Other than the ends self intersecting this seems fine to me. $\endgroup$ – Duarte Farrajota Ramos Jun 4 '17 at 2:03
  • $\begingroup$ Simply subdividing a plane and rotating and translating selections could work, with enough patience. $\endgroup$ – TinFellow Sep 16 '17 at 1:01

Look at it in Front View (Ortho). Note that with the rig you have it is designed so it will fold into a square, ignoring the end pieces. If you want something else like a pentagon maybe you should start with that shape and work backwards unfolding it. Or just change the shapes of the end pieces to be more like the rest.

square

pentagon

It looks like these are tiny math inaccuracies that add up as they go along the edge of the strip, which is why it gets wider towards the end. The 'tail' of your DEL and EL bones are at 5cm and -5cm, and if you make those 3cm and -3cm, the center stays together a lot better. You may need to tweak the size of other bones to get it exactly perfect.
