Sewing Machines, Sergers and Related Equipment summary/review


• All sewing machines operate in a similar manner.

• Choose needles and thread according to fabric type.

• Needles should be replaced when dull, bent, or rough.

• Adjusting the machine produces the best stitch.

• Controlling sewing machine speed comes with practice.

• The serger can stitch, trim, and overcast a seam at the same time.

• A serger creates different stitches with three, four, five, or eight threads.

• Special equipment and tools are used for measuring, pinning, cutting, marking, stitching, and pressing.

1. Sewing machine use. Wind the bobbin on a conventional sewing machine. Then thread the machine and stitch a row of regular stitches, basting stitches, and reinforcement stitches.

2. Serger use. Thread a serger and adjust the tension for each looper and needle. Then sew the stitches that the machine can create.

3. Safety poster. Create a poster of safety tips for using sewing machines, sergers, and equipment.

4. Basic tools and equipment. Make a list of the basic tools and equipment that a beginning sewer will need for a simple project.

Thread the Bobbin

The bobbin provides the underside thread for the sewing machine. Properly winding the bobbin is important to achieve the correct tension on the bobbin thread and have an acceptable stitch quality. The best source on how to thread your bobbin is the machine manual.

Most sewing machines wind the bobbin on the top of the machine before it's dropped in or placed in a bobbin case.

1 Place the bobbin on the bobbin winder. Consult your manual for the correct type of bobbin to use.

2 Place the thread spool in its position. Guide the thread to the one or two thread guides it must go through on its way to the bobbin.

3 Manually wind the end of the thread around the bobbin a few times. If the bobbin has access holes in it, bring the end of the thread through one of the holes and wind it around the bobbin a few times.

4 Gently slide the bobbin holder over toward the bobbin-winding regulator or brake. See close-up of an already filled bobbin engaged against bobbin-winding regulator in the photo on the right.

5 Hold the end of the hand-wound thread and slowly engage the machine. Allow the machine to partially wind the bobbin, covering the entire shaft of the bobbin with two to three layers of thread. Trim the end-tail thread that you've been holding.

6 Keeping the machine speed slow and even, resume winding the bobbin until the sound of the machine changes or the bobbin stops turning because it has filled and is touching the bobbin winding regulator or brake.

7 Slide the bobbin holder shaft and bobbin away from the bobbin winding regulator or brake.

8 Place the bobbin in the machine as shown on the next page. Leave a long enough thread tail to thread the bobbin area.

Note: A small number of sewing machines have bobbins that wind in their final position. These machines with a bottom-winding bobbin usually have a button or latch that must be engaged for the bobbin to wind.

Tie it in to the Core Science/Technology Curriculum:

1. Math. Visit a store to research the price of sewing tools and equipment. Using a list of basic items a beginning sewer might need, determine the total cost of the items.

2. Internet. Visit the Web site of two or more sewing machine and serger manufacturers. What machine features are highlighted by each manufacturer? What is the price range of sewing machines and sergers? What additional information is provided for sewers? Summarize your findings in a report.
