TENSION FACTORS THAT AFFECT THREAD TENSION • Thread color dyes affect the texture of the thread, which can affect how smoothly it slides through the embroidery machine. • Polyester threads would require nearly twice the amount of tension as rayon. • If you change the weight of the thread, tension will require adjustment. • Embroidery machine speed may affect tension - the slower the speed, the better the quality. • Excess dust and lint along the thread path can affect thread tension. If needed, adjust the thread tension as described in below sections. CHECK THREAD TENSION The tension of the bobbin and top threads affect the stitching that comes from every needle bar. Ideally, the tension (for satin stitching) will produce a one-third (1/3) bobbin thread running exactly down the center of the column, with one-third (1/3) top thread running down each side (1). If a small amount of the bobbin thread is visible, or there are thread loops on the right side, the top tension is too loose (2). If a large amount of the bobbin thread is visible, the top tension is too tight (3). 1 2 3 Under normal use, the user should temporarily stop the embroidery machine and check thread tension after the first 100 stitches of each color. Because of different types or thicknesses of cloth or backing being used, embroidery results may be different from what is expected; make samples before mass production. ADJUSTING THE THREAD TENSION Each design may require different tension settings. You can adjust the tension of the machine even while it is running. Experiment by making small quarter (1/4) turns on the upper tension knobs. until you feel comfortable with your design. • For metallic and polyester threads, turn the tension knob counterclockwise once. • For light color rayon threads, turn the tension knob counterclockwise 1-2 times. • For white rayon thread, turn the tension knob counterclockwise 1-2 times. • For medium color rayon threads, turn the tension knob counterclockwise 1-2 times. • For dark color rayon threads, turn the tension knob counterclockwise 2-3 times. • For black rayon thread, turn the tension knob counterclockwise 3 times. 26 - PREPARATIONS
