Elasticator

Fabric ....................................................... mediumweight cotton, 3" x 12"
............................................ 12" length of ½" nylon or cotton braid elastic
Needle ............................................................... 75/11 Stretch or Ballpoint
Thread ................................................................... 2 cones serger thread
......................................................................... 2 cones YLI Woolly Nylon
Presser Foot ............................................................................ Elasticator
Stitch ............................................................................. 4-thread overlock
Thread the serger for a 4-thread overlock stitch. Set tensions for a
balanced stitch. Attach the Elasticator to the serger.
Adjust stitch length to 4mm.
Increase the presser foot pressure.
Locate and raise the roller guide in the front of the presser foot. Turn the
handwheel to lower the needles. (This also lowers the feed dog.) Raise
the presser foot and insert the elastic through the slot and under the
presser foot until it touches the needles.
Lower the presser foot and serge a few stitches to catch and straighten
the elastic along the right edge of the slot. Turn the handwheel to lower
the needles.
Lower the roller guide. Using the small screwdriver, adjust the guide
plate on the presser foot to the width of the elastic.
Locate the pressure adjustment set screw (on the top of the roller guide)
and turn the screw counterclockwise to completely loosen the pressure
on the roller.
Place the fabric under the presser foot and begin serging. Slowly tighten
the pressure adjustment set screw to increase the pressure on the roller
and stretch the elastic. Note: Do not over tighten the screw. Excessive
pressure on the elastic will bind the fabric. Serge the elastic onto the
fabric letting the presser foot stretch the elastic for you.
Trim and mount the sample.
Return all settings to normal.
