（Figure 1 is a control block diagram, Figure 2 is a sheath thickness measurement mechanism, and Figure 3 is a control block diagram.
The figure shows a mechanism that obtains signals about the thickness and type of needle thread and a mechanism that measures the amount of needle thread being fed out. Figure 4 is a partially cutaway side view of the thread tension pressure adjustment mechanism. Figure 5 shows that straight stitching is ideal. FIGS. 6 and 7 are a top view and a sectional view taken from the feeding direction when zigzag stitching is ideally carried out. In the figure, 1 is a winding thickness signal, 2 is a fabric feed amount and needle swing width signal, 3 is a signal related to the thickness and type of thread, 6 is a comparator, 7 is a signal related to the actual needle thread payout amount, 8 1 is a thread tension pressure adjusting device, 9 is a sliding variable resistor, 10 is a presser bar, 11 is cloth, 12 is a feed dog, and 13 is an upper thread. r−−1 Bi==5 5− (
