More about the Bicycle tube bag….and Janome Acufeed + SFS system


I have had a few queries about the recycled bicycle inner tubes used in this bag. This was posted recently under the title:  JUST LOOK WHAT THE JANOME ACUFEED SYSTEM CAN DO.

The bicycle tube is cut into strips (and cleaned, of course).  I guess you could certainly cut up perfectly good, new bicycle tubes if you no longer had a need to go cycling!

The needle I used is a JANOME denim size 16 so it is quite a strong large needle!

I used regular polyester sewing thread – again for the strength of this type of thread. I doubt a rayon thread would work: pretty though it is for embellishment, it lacks the strength for sewing , especially projects such as this.   Use the same thread in the bobbin.

I found that the Acufeed built-in walking foot system on the Janome Horizon 7700QCP (also available on the Janome MC6600P), is the perfect way to deal with this kind of funky and challenging “fabric”.

Janome's incredible Acufeed system

The Janome Acufeed system works on a rectangular feed dog action: in other words the lower and upper feed dogs work in perfect unison all the way along the top of a rectangle…..not like many other walking feet which work on a circular action so that the only time the upper & lower feed dogs actually work together is that little part at the top of a circle. They work……but nowhere near as effectively as the Janome Acufeed system. Visit your local Janome dealer today for a demo on how this truly amazing feed system works.

Note the DOUBLE upper feed dogs for optimum feeding

Another very interesting (albeit a technical point) is that many Janome sewing machines have a 7 point feed dog system: this means that there are no fewer than 7 feed dogs below the needle plate which work to feed fabric through the machine. These work totally in sinc with the TWO upper feed dogs of the Acufeed system so that Janome can truly boast that they have an SFS….Superior Feed System. As I said, see your local Janome dealer today for a demo and/or test drive the machines yourself: you will be amazed!

Note the SEVEN feed dogs including the 2 little advance feed dogs.

Why are those Advance feed dogs so important? They are the ones responsible for first “catching” the fabric and feeding it to through the machine.  Wonder no more why it is that most Janome sewing fans have little or no need of those silly little “stitch buddies” (those little pieces of fabric that you sew onto before you begin sewing and then sew off onto at the end of your seam.) The only reason you might need these tatty little scraps of fabric, is if you (sadly) have a machine which does not have this great 7 point SFS feed system! What then happens is that your fabric does not get “caught” by those nifty advance feed dogs and may get sucked down below the needle plate resulting in a horrid thread jam. Hence the use of the “stitch buddie” to prevent this.  HOWEVER,  the GOOD NEWS is that most loyal Janome sewers do not need to bother with this as the SFS feed system with its Advance feed dogs take care of this annoying little hassle.

THANK YOU, JANOME!! See your local Janome dealer today if your current sewing machine does not have Acufeed or SFS. You will not look back once you add these incredible features to your sewing room!

    Thanks so much for expanding on the inner tubes information – I’m hoping my local cycle shop will provide a supply of old tubes to work with.
