The movemenL of the Carriage
revolves
the Friction wheel at a
constant
pace
through the KR Peeding Lever,
then the Fliction
Wheel
transmits
the movement to the Friction
Disc affixed to the
Platen Shaft. Therefore, the
feeding
anount
of
the P1aten is
determined by the
position
of the Friction Wheel relating to
the
r.riction
Disc, as shown
in the diagiafiL. The farther the Friction
wheel
stays away from the centre of the frictlon Disc, the snaller
the
feeding amount of the Platen.
Therefore,
the
feeding amount
(number
of
rows)
is set by the turn-
ing of the
Ro\"/ Number Dial.
