Help (advice) with building a braiding machine?

I've been working with braiding plastic shopping bag strips into rope, and by hand it's a slow and tedious process.  I know that braiding machines have been around for ages, so the patent on many of them has to have elapsed.  I've Google'd and Bing'd and Yahoo'd my heart out looking for how to build a simple one to no avail.  The only thing that comes back is Chinese sellers of a commercial braiding machine.

All I want is something that I can build, a hand crank mechanical kind, that can braid 7-10 strands into a larger rope. It doesn't even have to go fast, in fact I'm fine with it being slow.

Can anyone provide plans for one?

UPDATE:
Ok so I think I have plans, but now I could use some advice with how to go about fabricating the sprockets.  One idea is to purchase a premade sprocket and modify it, then use it as a master for a mold to create more.  I was thinking of either doing the whole dissolving styrofoam with Acetone then pouring the plastic in the mold thing, or possibly adapt the Oogoo instructable.  Thoughts??

Update 2:  My latest brainstorm leaves me thinking that I could use a bicycle sprocket (gear) as a master and then make a mold from it, then make duplicates from the mold.  Thoughts???

And here's yet another design which accomplishes the same thing.

good day DrPeper, i was just to fabricate a braiding machine too..i will only use, three strands of thread to braid..but my design for the machine is not yet finished..i dont know how the spindle will transfer from the first sprocket to another one.can you explain me?does the centrifugal force has something to do with it?.i am thinking of creating an interchangeable path like in the railways to guide the sprocket to the second sprocket and vice versa, but it is too complicated..

thanks in advance..

i am wanting to fabricate a 3strand braiding machine out of wood. If you, tiojhnm or drpeper can help me with figuring out how to put together a gear system to mechanize it. I have designed and cut out a figure eight track. Gonna use dowels to hold bobbins. Just wanna figure out how to make it a lot easier. Think you guys can help?

I actually haven't gotten any further than paper drawings for this project yet, so I'm not sure how much help I might be.

I've had to put this project on the back burner for a while. And I probably won't be able to get back to it until after the holidays. But I think we are both on the same path here. My prototype is going to have two rotating sprockets and three spindles. But I'd *love* to see pictures of what you have so far, and offer any help that I might be able to.

i have just read the answer to my question. here it is, www.nzmeccano.com/image-56255

using a waggler is the solution..

i cant post pictures or diagrams of my prototype here due to personal matters..im sorry..

another problem that arises is the design of the bobbin. i cant imagine the principle of the tension principle in the bobbins used for braiding machine that are available in the net.

Well I'm gonna have to take a closer look at that "waggler", because I don't understand it from the image. Also the image you attempted to post about the bobbin tension-er didn't work. But that is a concept I've thought about. I was hesitant to post any diagrams of my ideas until I can see what works. But the professional bobbins don't seem to me to be too difficult to understand.

the waggler acts like a course changer, the spindles rotate the waggler as they pass through it..

i have realized the principle in the bobbin.it takes me some time to realize the principle behind it.the spring in the bobbin plays the important role there..when the lever, attached to the spring,which is also attached to the thread lifts, the other end of the lever triggers the bobbin to rotate.

here is the other problem..the bottom of the spindle is being in contact with the platform..the spindle will move around its path..there is a friction between the bottom of the spindle and the surface of the platform..do i need to add lubricants to it?

make something out of Teflon washers.
