lace a slight tension on the material in the sewing direction and a finer seam finish can be obtained. The minimum overedge stitch width that can be obtained for rolled hemming is approximately 1. 5mm (1/16 inch) since the cutting width cannot be set below 3.5mm (9/64 inch). Additional lnformation About Rolled Hemming Apply a small drop of liquid seam sealant to the end of the seam. Allow to dry, then cut the chain close to the stitches. To Secure the Rolled Hem Thread Chain Note: Test the liquid seam sealant for color fastness before use. 40Remove Remove Needle thread Needle thread Upper looper thread Topside Lower looper thread Underside

25. STITCH VARIATIONS AND

SEWING TECHNIQUES How to Sew a Flatlock Decorative Seam (1) Machine Set Up A flatlock stitch is achieved by adjusting the tension of the 3-thread overlock stitch, sewing the seam and pulling the fabric apart to flatten the seam. The flatlock stitch can be used as a construction and decorative stitch or for ornamentation only. Remove the left or right needle. Begin with the machine threaded and tension balanced for the 3-thread overlock stitch (page 29). Loosen the needle thread tension (green or bule) generously. Loosen the upper looper thread tension (orange) slightly. Tighten the lower looper thread tension (yellow) generously. (2) Flatlocking a Seam Place the fabric wrong sides together to sew a decorative stitch on the right side of the garment. Sew the seam, trimming the excess fabric. The needle thread (green or blue) will form a V on the underside of the fabric. The lower looper thread will pull into a straight line at the fabric edge. 41(3) Decorative Flatlocking Pull on opposite sides of the seam to pull the stitches flat. Place the movable upper knife in the nonworking position (page 25). The fabric is not trimmed or this stitch. Fold fabric wrong sides together. Position the fabric so the seam is sewn with par of the stitch extending off the fabric. Pull on opposite sides of the stitch to flatten. (4) Additional Information About Flatlocking The tensions must be correctly adjusted for the fabric to pull flat. The upper looper thread is the prominent thread in the flatlock stitch. Place a decorative thread in the upper looper and inconspicuous threads in the lower looper and needle. For a ladder stitch, sew seam with right sides together. The needle thread will be the prominent thread that creates the ladder (A).

Underside TopsideThe excess fabric is trimmed and the hem is sewn and the raw edges are overlocked in one operation. The overlock blind hem is best suited for sewing knit wear. It provides a durable finish that is almost invisible. Remove the left needle and adjust machine for a narrow 3-thread overlock stitch. Note: The three-thread flatlock stitch can also be used. Set the stitch length dial at 4. Fold the hem to the wrong side of the fabric, then back to the right side with 6mm (1/4”) beyond the fold. Stitch on the extended hem edge, allowing the machine needle to barely catch the edge of the fold. Remove Remove

How to Sew an Overlock Blind Hem Sew de corative pin tucks on the fabric before cutting out the garment. Remove the left needle and adjust machine for a narrow 3-thread overlock stitch. Note: The rolled hem stitch can also be used for this technique. Place the movable upper knife in the nonworking position (page 25). mark the fabric with the desired number of pin tucks using a water soluble fabric marker. How to Sew Pin TucksFold the fabric with the wrong sides together and sew. Press the pin tucks in the same direction. Cut out approximately 2 cm (51/64 inch) from the corner, in line with the overedge seam edge. Sew one stitch beyond point (A) and stop. Raise needle and presser foot. Pull the fabric to the rear of the machine just enough to release the thread caught on the finger of the throat plate. Note: Presser foot has been removed to show detail. Turn the fabric and lower the presser foot so that the knife is positioned in line with the cut edge. Pull slack threads up, then start to sew. Turning Square Corners Cutting line Cutting line Cut Slit (1) Outside Corner Cut fabric at seam edge. (2) Inside Corner 44Place the movable upper knife in nonworking position (page 25). Stitch on cut edge of fabric. Stop sewing before you reach the corner and fold the fabric to the left to straighten the corner. Continue to sew slowly holding the fabric edge in a straight line moving the fold as you sew. Insert pins to the left of the presser foot. The pins will be easy to remove and are away from the cutting action of the knives. Caution: Sewing over pins will damage and/or destroy the cutting edge of the knives. Pin Placement Thread a large eye, hand sewing needle (such as a tapestry needle) with the thread chain. Insert the needle into the end of the seam to secure thread. Securing the Thread Chain Needle position Note: To secure a rolled hem thread chain, see page 39. 45Inserting twill tape while overedge sewing will stabilize the seam. Insert the tape through the hole in the front of the foot. Position the tape under the foot to the back of the machine and sew the garment seam. The tape is attached as the seam is sewn. How to Reinforce a Seam position. Insert filler cord such as yarn or twill tape through the hole in the front of the foot. Position the filler cord under the foot and chain off the desired length. Chained off braids can be used individually or woven into 3 or 4 ply braids. Braiding by Chaining Off Place the movable upper knife in nonworking 46Danger: Before cleaning your machine, disconnect power line plug from the wall receptacle. Clean the lint from the looper and knife area often with a dry lint brush. Note: Lint brush is an optional part. An overlock requires more maintenance than a conventional machine mainly due to two reasons.

1) A lot of lint is produced due to the cutting action

2) An overlock runs at a very high speed and needs

to be oiled frequently to lubricate the internal working parts. Cleaning the Machine

Before lubricating your machine, disconnect power line plug from the wall receptacle. The oiling points shown in the diagram, should be oiled periodically. Note: Use sewing machine oil. Do not use any other oil or damage could result. Oiling the Machine 47Danger: Before replacing the stationary knife, disconnect power line plug from the wall receptacle. The stationary knife should be changed when it becomes dull. The stationary knife can be replaced according to the directions provided, however if there are any representative to make the adjustments. Be su re that the power line plug is disconnected from the electric source. Open the looper cover and set the movable upper knife 1 in the nonworking position (page 25). Loosen the stationary knife set screw 2 and remove the stationary knife 3 . Place a new stationary knife in the groove of the stationary knife holder. Tighten stationary knife set screw 2 . Return the movable upper knife 1 to its working position. How to Replace the Stationary Knife difficulties experienced, consult your Singer
