Parts of a machine and their function :--- The basic parts of a sewing are listed
below most of these parts are stark of .
1 .SPOOL PIN :--- Hold the spool of the thread .
2 .THREAD GUIDE :---Hold the thread in position from the spool to the
needle .
3 . TENSION DISC :---This is a simple mechanism where two
concave discs are put together , with the convex sides facing each
other . The thread passes between the two . The tension of the
thread is adjusted by a spring and a nut . which increases are
decreases the pressure on on the disc .
4 . Take - up lever :----At the out side end of this lever , there is a
small whole through which the thread passes . this lever moves
down to loosen the top thread while the stitch is being found . Then
it moves up and pulls the loop of thread tight to complete
the stitch .
5. NEEDLE BAR :--This is a steel rod which holds the needle at one
end with the help of a clamp .
6.BOBBIN CASE :---This moves in to position to catch the top thread and form the stitch
as the needle is lowered in the bobbin chamber .
7. PRESSER FOOT :--This moves in to position to catch the top thread and form the stitch
as the needle is lowered in the bobbin chamber .
8 .PRESSERFOOT LIFTER :--This is a lever attached to the presser bar for
raising and lowering the presser foot .
9. STITCH REGULATER :---This controls the length of the stitch . some
regulaters can be set to stitch in reverse .
10 . BOBBIN WINDER :---This helps the winding of thread on the bobbin , some are made to
stop automatically when the bobbin is full .
11.FLY WHEEL :---When this is made to revolve it works the machanisam of the machine .
12. CLUCH OR THUMB SCREW :---This is in the centre of the fly wheel and it engages and disengages the stitching
machanisam .
13.SLIDE PLATE :--This is a rectangular plate which can be slide open to
remove or to put in the bobbin case .
14. NEEDLE PLATE :---This is a semi circular plate with the whole to allow the needle to
pass through .
15. FEED DOG :---This consists of a set of teeth fitted below the needle plate . it
helps the cloth move forward while sewing .
16. FACE PLATE :---This is a cover which when remove gives axis oiling on needle bar , presser bar and take -up - lever .
17 .SPOOL PIN OR BOBBIN WINDING :---Spool of thread is placed on this at the time of winding the bobbin .
