7-9-2 Setting of the thickness detector
(1) Place material of the maximum allowable
thickness(10mm) or spacer between the upper and
lower clamp (NO. ).
(2) Pull down the air cylinder(NO. ).
(3) Loosen the setting screw(NO. ).
(4) Pull the thickness detector (NO. ) downward until it
touches the lower clamp (NO. ).
(5) Tighten the setting screw (NO. ).
(6) At this time, make sure the sensor I5 (NO. ) of the
thickness detector cylinder (NO. ) functions. At
upper (normal) position the sensor I5 should be ON.
7-9-3 Setting of the thread wiper
The thread wiper pulls the thread at a proper angle for
the heater and the thread on to come in contact
correctly as for the thread. It is proper that the thread
angle almost has the relation of the 90 degree with the
heater. Moreover, a suitable tension should be added
for avoid the thread should not escape from the
heater at this time. Please adjust the thread
wiper device as follows.
(1) Remove the rod cover (NO. ).
(2) Loosen the nuts (NO. ).
(3) Set the swing movement of the thread wiper
(NO. ) by rotating the nuts (NO. ) up or
down.
(4) Tighten the nuts (NO. ) .
(5) Replace the rod cover again.
(6) After adjustment, check the position of the
sensors I9(NO. ) and IA(NO. ) of the
wiper cylinder (NO. ).
At the initial position of the thread wiper, the
sensor IA must be OFF and the sensor I9
must be ON.
The thread wiper should move freely past under
the needle.
To correct the height of the thread wiper
(1) Place material of the maximum allowance
thickness (10mm) or spacer between upper
and lower clamp.
(2) Swing the thread wiper manually past under
the needle and check the thread wiper
should not thereby strike against the needle.
If the wiper interfere, adjust by following
procedure.
(3) Loosen clamping screw (NO. ).
(4) Adjust the height of the thread wiper.
(5) Tighten clamping screw.
