Adjustment Procedures Results of Improper Adjustment
™ Adjust the timing by loosening screw
#0
of the spreader
eccentric cam @9 and rotate the spreader eccentric cam @9.
™ Adjust the stroke by loosening the nut #1 and move back and
forth. If it is moved toward you, the stroke becomes small, and
to the back it becomes large.
™ Adjust the height of the spreader by loosening the screw #3
and moving the spreader #2 up and down.
™ Adjust the clearance between the spreader and left needle by
loosening the screw #3 and move the spreader #2 back and
forth.
™ Adjust the extreme left position by loosening the screw #4 and
move the spreader #2 to the left and right.
™ If the timing is too advanced, the
needle does not catch the covering
thread when it descends. This is
likely to cause the skipping stitch.
On the contrary, if the timing is too
retarded, the right needle is likely to
break as the resistance when the
covering thread is pulled from the
spreader becomes large.
™ If the movement amount of the
spreader is not set right, it will cause
skip stitching of the top covering
thread.
™ If the height of the spreader is not
set right, it will cause skip stitching
of the top covering thread.
™ If the clearance between the
spreader and needle is small, it will
cause the needle breakage. If it is
large, it will cause skip stitching of
the top covering thread.
™ If the protruding amount of the
spreader is large, it will cause
uneven stitching of the top covering
thread. If it is small, it will cause skip
stitching of the top covering thread.
™ If the position of the needle clamp
spreader thread guide is not correct,
it will cause skip stitching of the top
covering thread.
™ Adjust the needle clamp spreader thread guide #7 by loosening
the screw #8.
™ If the height of the fixed spreader
thread guide is set as high as 4 mm,
the top covering performance by the
spun thread is improved. But,
defective looping may occur when
other threads are used.
™ If the position of the fixed spreader
thread guide is not correct, it will
cause skip stitching of the top
covering thread.
Adjust the fixing spreader thread guide #5 by loosening the
screw #6.
