Spool pin is a small metal rod on the body of the sewing machine. The main function of spool pin is to hold the spool of thread (Figure 8.2).


Thread Guide

Thread guide is a small metal ring, on the face of sewing machine. It keeps the thread in position and guides the thread from the spool to the needle.

Tension Disc

Tension disc is a metal spring with con-cave disc and screw. The thread is fed into the tension disc in between the two con-cave disc, screw and spring to pass the thread freely to the needle. The screw can be adjusted to increase or decrease the tension (Figure 8.3).


Take-up Lever

Take up lever is, hook shaped and the thread is passed through this to make upward and downward position, to pull thread in the sewing machine and to enable the needle to stitch.

Needle Bar

Needle bar is a steel rod to hold the needle at one end with help of a clamp.

Bobbin Case

Bobbin case is a metal circular cap shaped part which holds the bobbin. The upward thread helps to bring the lower thread in the bobbin from the bobbin case to make a stitch (Figure 8.4).
