5. ADJUSTING THE FEED AMOUNT OF THE ROLLER
Loosen screw 1when adjusting the feed amount of the
roller. Feed amount is decreased when link 2is lifted.
Feed amount is increased when link 2is lowered.

6. FEED TIMING OF THE ROLLER
Notch A in collar 3aligns with notch B in the puller eccen-
tric cam when the roller is placed in the standard position.
When changing the feed timing, loosen two setscrews
2in puller eccentric cam 1to adjust. When the cam is
moved in the direction of C, the start of the roller is ad-
vanced, and when it is moved in the direction of D, the
start of the roller is delayed.
7. ADJUSTING THE CLEARANCE BETWEEN THE GEAR ROLLERS (PL12)
1
In case of the gear type roller, loosen nut 2and adjust the
length of screw 1so that the clearance between the top
and the bottom rollers is approximately 0.3 mm in the state
that the rollers are lowered.

9. ADJUSTING THE CLIUTCH TENSION SPRING
1
Adjustment is performed with clutch tension spring 1so
that the top roller does not overrun at high-speed rotation.
When performing the adjustment, loosen cap nut 2, and
turn nut 3to the right (clockwise) to increase the spring
pressure. When decreasing the spring pressure, turn nut
3to the left (counterclockwise).
After the adjustment, tighten cap nut 2.
(Note) The standard of the spring pressure is to such an
extent that clutch tension spring 1turns with
the small force of your nger after tightening
cap nut 2.
