The system ELNA has included on the EL7300 and EL740 Excellence is known as the IAF: Integrated Adjustable Feeding 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 Elna IAF system. Visit your local Elna dealer today for a demo on how this truly amazing feed system works.
Another very interesting (albeit a technical point) is that many Elna 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 IAF system so that Elna can truly boast that they
have an SFS….Superior Feed System.
Why are those Advance feed dogs so important? They are the ones responsible for first “catching” the fabric and feeding it through the machine. Wonder no more why it is that most Elna 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 Elna 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, ELNA!! See your local ELNA dealer today if your current sewing machine does not have IAF or SFS. You will not look back once you add these incredible
features to your sewing room!
