The Needle Thread Tension
Once the bobbin thread tension has been set correctly, the final stitd1 ap-
pearance can be regulated by the upper tension dial.
Sketch Ill (Fig. 27) depicts the perfect stitch. Both threads are interlaced in the
center of the material.
In sketch I (Fig. 25), the threads interlock on the underside of the fabric.
Cause: Upper tension too loose or l ower tension too tight.
In sketch II (Fig. 26), the threads interlock on the surface of the fabric.
Cause:
Upper tension too tight or lower tension too loose.
In zigzag sewing, the lock of the thread should occur exactly at the zigs ana
zags of the seam (Fig. 32).
