(4) How to Adjust the Pressure Between the Feed Wheels of M2.
Please refer to the following drawing. (Fig. 1)
a.
horizontal surface of the bottom of #3(the beginning thread of #2 should not be
extrusive to the bottom of #3).
b.
Please loosen #4 & #5.
c.
Please put the strap you are using (called #7 in the drawing) between #6 and #8.
d.
Please put the wrench (the drawing shown as #9) into the #6 and turn #6 counterclockwise
e.
Take away the strap.
f.
Please turn #2 down 1.5 cycles and then tighten #1.
g.
Please pull down #11 Spring for about 3mm and then fix the #12 Nut.
However, when the strap width is 9mm and the arch size is 850mm(W)
or 1050mm(W), the pressure will not be enough even though the #11
is put in the end of #5. In this case, you will need to add the
additional #13 to increase the pressure.
h.
Now, the pressure of rollers has been set. Please pay attention that there should be
not any clearance left for the #10 Shaft to move after you have tighten the #5 & #4.
Please loosen #1. Then, turn up #2 until its beginning of thread is on the same
a little bit so that #6 will press on the strap lightly (not put too much pressure on the
strap). At the same time (when the #6 touching the strap), please also make #5 press on
#2. Then, tighten #5, and #4 while you still have not released the wrench #9. After you
have tighten the #5 and #4, then you can take out the wrench.
