Help (advice) with building a braiding machine? Answered

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?

These plans look similar to existing braiding machines. Why don't you look around the market for a 2nd-hand braiding machine, rather than re-invent the wheel. I have bought them myself in Australia for around $5000 each - but make sure you get a model that uses good capacity bobbins. Some of the bench mounted machines have bobbins that would be too small for your needs. You will still need to build a winder for the bobbins if you still want to build something - but a winder is a lot simpler than a braider. I suggest a 16 carrier machine. Easy to load ( than a 24 carrier) and can still make a good sized rope depending on your initial strand size. Don't forget you will still need to twist 'S' and 'Z' for a braided rope product - Good Luck !

Um well the main reason for not buying one would be that I don't have a spare $5000 to just throw away! Not to mention it completely misses the point.

And I'm completely confused by your "s" and "z" comment??!

Please look up S and Z twist in Wikipedia.

Actually S and Z twists, I wouldn't technically consider braiding. But thank you for your input!

For a balanced final braid you will need to load half your bobbins going in one direction with, for example an S-twist strand, and a Z-twist strand on the bobbins that are going in the other direction. As such you will also need a twisting machine for preparing your strand / a winding machine for loading your braider bobbins, and a creel for housing your primary cheeses.- So just having a braiding machine is just the start of it. Good luck !

About how the spindle pass from a gear to the next I was thinking on this image

http://www.strutpatent.com/image/get/2011/full/US07905237-20110315-D00018.jpg
If P1 is the lever and the circle close to P1 is the fulcrum (hub) ,
the lever could be simply linear, could be forced by an elastic/spring
who push/pull her to the right to a stop point and long enough to be
intercepted by the spindle who arrives on the left gear (it could be simply something like that

http://www.impiantigpl.net/274-200-large/cablaggio-diinterfaccia-usb.jpg or similar )

. At this point
the spindle push the lever to the left until the spindle finds the new
housing on the right gear, the lever force it to right and when the
spindle goes ahead the lever return to the initial position.

Would it be any easier for the whole sprocket system to move (rather than each sprocket spinning)? The opposing rotational direction of each group of sprockets can then be implemented using an inner-outer ring system. A bit like the diagram at page 2 of : http://www.cs.arizona.edu/patterns/weaving/articles/amd_ropm.pdf

Also this cool video (http://www.youtube.com/watch?feature=player_embedded&v=K5NfEoOO1Eg) hints(??) at maybe another way of designing the sprocket system. This auhor of this page(http://www.techlug.fr/Forum/topic7706.html) is similarly building a braiding machine.

I have not read all the comments but have you thought about making it out of wood? Some of the first looms were wooden.

Yes, I have considered that, and that's probably the way I will go. I just got access to a laser cutter and a 3d printer, so I'll be moving forward on this project after the new year.

3D printing. google 'reprap mendal90'. I was directed to this page looking for ideas to make exactly this with a 3D printer.

I'm gathering the parts, and learning as much as I can about the tech. I was planning on using a planetary gear set-up to make it work, but now I'm noticing that the teeth don't mesh in the image above. Either way, there is a long list of things I want to print.

Hey I just started with the same idea :D I want to build an OpenSourceBraidingMachine (OSBM) which is 3D printable. I just started on sunday. Now I googled and found that thread. My concept is a little different and orientates on commercial braiding machines. I hope I will find time for this project (next to the other stuff ;) ).

bryanhodson: Do you have already built something?

hello..

my braiding machine have been fabricated.but when i test it, the braid is not compact..
the braiding angle is too small..the ratio of rotational speed of the spindle to take up speed is 2.5..

take up speed is 20 RPM
rotational speed of spibndle is 50 RPM


can someone help me? do i need to make the take up speed slower?

Hello tiojhnm2,

Your take up speed is likely to fast. One factor that contributes to the tightness of the braid is the take up speed. They call this - picks per inch - on a standard New England butt braiding machine. On this type of braider the picks per inch is controlled by a set of different size gears that u can change out on the take up wheel.

To change the braiding angle u need to have an adjustable mandrel (a flat piece with a hole in which the braid runs up through to the take up wheel). This piece needs to adjust up and down and it helps set the the braid angle.

Hope this info helps. Good Luck!

I'm not sure where you made it with your project here, but according to the documentation that you have it looks like you are down to figuring out how to pass the spindles from one sprocket to the other (and alternating directions).

Stealing this idea from http://www.youtube.com/watch?v=pZW15Uc-00U i came up with a slightly modified version.

At the interior intersection of 2 sprockets you will have a (almost) triangle wedge mounted so it can pivot left and right. (this will be used to move the spindle from one sprocket to the other). The shape of this piece is has to do 2 things, 1) move the spindle from left to right, and 2) once the spindle is moved, "hold on" to the spindle for a little bit to "flip" the piece over (so that it will move the next spindle in the opposite direction.)

Of course your spindles will have to reach below the sprocket (which you have in your design)


PS.
Just thought about this a little more, the triangle will not always be on the interior, but will be on alternating sides depending on the gear it is on.
If you are looking at the diagram you have above, and going clockwise starting with the gear labeled "M" (M1 = "M", M2, M3,...) the intersection of M1-M2 is inside, M2-M3 is outside,....

I haven't forgotten about this project. It's always a matter of time and other projects taking priority. I just ordered some axles and gears (lego) so I'm going to start out with a 3 strand braiding machine as my first prototype.

However I did run across this rotary braiding machine in lego that I think does the same thing but uses a different mechanism, which I find quite intriguing.

I've actually found this one before, however it isn't as smooth as the versions that I am attempting to replicate.

The hard part is figuring out the right keywords, and also having enough information up front to construct a good search.

"Multistrand braiding machine" actually returned a site with two different LEGO machines, but since the links and videos on the page didn't work, it wasn't very useful :-(

Yeah, I looked at those but the ones I found were only 3 strand and one that I found really just twists, it doesn't braid.

Dr Peper - have you got any further on the braiding machine. I am debating the same issue but I need to braid specialized wool braiding for reproductions of War of 1812 military hats. Lots of small quantity but different colour combinations. My own braiding machine would solve a lot of problems. Have you figured out how to pass the spindles around? Thanks

Unfortunately I haven't gotten any further on this. I've had to put this project on a back burner for a while. Mostly because I don't have any lego technics or erector/mechano sets to build a prototype with. But also because I have entries that I'm preparing for all the contests lately.

As for passing the spindles between sprockets, I was just thinking of a small strip of material (like a plastic strip) to act as a guide to kick the spindle off of one sprocket to the other.
