Let’s Learn the parts of the Sewing Machine These are our Sewing Machines 1. Reverse Lever The reverse lever allows you to stitch in reverse. We use reverse to make our stitches secure at the beginning and end of seams. 2. Pattern Selector The pattern selector lets you determine what kind of stitch you will be making, such as straight stitches or an embroidery stitch or zig-zag. 3. Stitch Length Stitch length determines the length of the stitch. The range is from 0 to 4; the longest is 4 0 the shortest stitch. 4. Bobbin Winder The bobbin winder winds the thread from the spool to the bobbin, mechanically. 5. Spool Pin Spool pin holds the spool of thread. 6. Thread Tension Thread tension determines the tightness or looseness of the stitch. *Students are reminded not to move this dial; each machine is set for the number on the tension dial that it needs. 7. Pressure Dial The pressure dial determines how much pressure the presserfoot will have on the fabric. More pressure may be needed for light weight fabrics, and less pressure for heavy, or thick fabrics. 8. Face Plate The face plate is a cover that covers all the inner working parts of the sewing machine. 9. Check Spring Holder The check spring holder is actually hidden in our machines. It works with the thread tension to slow down the amount of the thread going to the needle. 10. Sewing Light The sewing light helps you to thread the needle and to see your stitching; both day and night. 11. Feed Dogs Feed dogs are a “teeth-like”part that works with the presserfoot to pull your fabric through the machine. 12. Throat Plate The throat plate has stitching guide lines on it and has a hole for the needle to pass through to the bobbin casing 13. Slide Plate The slide plate is a clear plastic cover that covers the bobbin case to keep dust and dirt out of the moving parts area of the bobbin case. 14. Presserfoot The presserfoot holds the fabric against the feed dogs; so the feed dogs can pull your fabric through the machine. 15. Needle Clamp The needle clamp is a black clamp that tightens to hold the needle in place. 16. Presserfoot Lifter The presserfoot lifter gently lifts the presserfoot up and lowers it against the feed dogs. Note: the presserfoot must be lowered before you begin to sew; or fabric will not move through the machine! 17. Take-Up-Lever The take-up-lever pulls the thread back after each stitch, so that the stitches will lay evenly into the fabric. 18. Handwheel The handwheel raises and lowers the needle. You must always pull the handwheel towards yourself to prevent tangling of the threads. 19. Clutch Knob The clutch knob is located inside of the handwheel. It is a safety feature of the sewing machine that when pulled out, prevents the needle from jabbing up and down when winding a bobbin. 20. Power Switch The power switch turns on the power on the sewing machine and also turns off the power, electrically. 21. Power Socket The power socket connects the power source to the sewing machine. 22. Foot Pedal The foot pedal operates the speed of the sewing machine, electrically. 23. Thread Cutters The thread cutters cut the threads at the end of a row of stitching to disconnect your fabric from the sewing machine. hand wheel
