Fig. 11 fCi

TO REGULATE THE TENSION

If upper tension is too loose, under thread draws

upper thread down, thus forming'asmall knot or

loops, as shown in Fig. 11 (A). If upper tension

is too tight, under thread is drawn up as shown

in Fig. 11 (B). Fig. II (C) illustrates how the

threads lock in the center of the material when

tension is properly set.
