One-Push Air Threading System--Tedious threading of upper and lower loopers are a thing of the past. Simply insert thread into the specially designed ports and your thread is transported to where it needs to be with an easy push of a lever
8-Piece Feed Dog System--With strategically placed feed dogs in eight locations, the eXtend 864 Air will easily grab and feed your fabric. From slinky knits to denim, the eXtend 864 Air will meet the challenges of your sewing projects.
Built-in One-step Converter--Changing from a 3-thread to a 2-thread application has never been easier! Simply place your finger under the converter and flip it into position. Now, you’re ready to sew delicate rolled hems or reduce the bulk in your overlock edge.
Built-in Needle Threader--An Elna first! With a built-in needle threader, manually threading your serger needles is a thing of the past. One unit provides easy threading of both the right and left position needles.
Safety First--There are three micro-switches for added safety to the sewist. The eXtend 864 Air will only be able to serge if all three switches (located in the side cover, looper cover and the Presser foot bar) are engaged.
Integrated Adjustable Dials--The Stitch Length Adjustment and Differential Feed Adjustment have been integrated into 1 dual function dial. Easily grip the textured dials to change your stitch length any time (even while sewing) to get stitches between 1.0-5.0mm. The unique differential feed device prevents fabrics from puckering, lets you adjust the stretchiness of our stitching as you sew, and enables you add ready-to-wear effects to your sewing. Adjustable from 0.5-2.0mm.
Fine Adjustments--Easily make adjustments to cutting width, access the upper knife release knob and switch to rolled hemming in one easy slide of the stitch finger lever. All of these adjustments are now located on the right side of the sewing bed for ease of operation.
Speed, Strength, Stability--The main shaft is newly redesign in the eXtend 864 Air. Two ball bearings provide low torque, giving you greater stability at higher serging speeds and the benefit of added durability.
Bed Size--Serge through bigger projects with the wide flat work space. The eXtend 864 Air offers ample sewing area with a sewing bed of 4.65” wide in front of the serging needle and 5.59” wide behind the needle. The bed is 9.67” deep as well.
Easy Lay-in Threading--With improved slide-and-go thread guides, quickly and easily lay the thread in place. The slide-and-go thread guides take the guess work out of threading the upper tension discs – preventing errors in threading the machine correctly.
Foot Pressure--Easily adjust the foot pressure to accommodate sewing on a variety of fabrics, or to accommodate optional accessory feet.
