sewing is decreased and when it is lowered, the
thread remaining length at the start of sewing is
increased.

ing when using non-elastic thread, properly ad-
just the remaining length of top-covering thread
at the start of sewing using setscrew !0 and
minimize the remaining length of looper thread at

of sewing is short, stitch skipping or slip-off
of thread from needle eyelet at the start of
sewing is apt to occur.
