The new air threading system makes it effortless to thread your machine. You can thread both the upper and lower looper by just inserting the thread into each port and pressing the threading lever: a blow of air pushes the thread through the looper and you’re done. A time-saving feature for tangle-free sewing!

A handy needle threader puts an end to fiddly threading and you can quickly get started or change threads as you sew. Simply slide the lever of the needle threader down and easily thread the right and left needle.

With a broad choice of stitch programs and the possibility of stitching in a different number of threads, our eXtend overlock and coverlock models ensure high-quality results on all types of fabrics and finishes.

The elna eXtend 664PRO and 845 models feature a reference panel showing the required settings for the selected program. A practical user guide to set up your machine step by step without forgetting anything important.

Stitch length, differential feed and pre-tension: all the settings are easy to recognize and access. Depending on the type of fabric you are sewing, you can turn up or down the differential feed to prevent the fabric from stretching or slipping.
