2) Centering the carrier pin in longitudinal direction
If the carrier pin cannot be properly centered by following the procedure 1), keep screw 3 loosened
and perform the following adjustment. Loosen two locknuts 4 (the left-handed screw is located in front
of the locknut) in the end of the rod. Loosen screw 5, and move urethane rubber 7 from the end face
away from the LM guide 8. Move connecting rod 6 until rotary rod 2 is brought to the position where
it smoothly enters centering ring 1. Then press the urethane rubber 7 against the LM guide 8 so as
to eliminate a longitudinal play. Confirm that the carrier pin is correctly centered then tighten nut 4 so
that connecting rod 6 does not rotate any longer. Then tighten screw 5. After the carrier pin has been
fixed with respect to its longitudinal position,the carrier pin should be laterally positioned and fixed in its
cause. It is, therefore, necessary to re-center the carrier pin both in the lateral and longitudial direction.
＊ The urethane rubber 7 is excessively pressed against the LM guide 8. → The excessive contact
between the urethane rubber and the LM guide can be corrected by providing a small clearance
between them.
(Caution) Perform the aforementioned adjustment only when it is necessary. If necessary, be sure
to confirm the following points.
1 The spinner oscillating arm does not have any longitudinal play when it is in its origin.
2 The spinner oscillating arm is correctly centered when it is in its origin.
3 The spinner oscillating arm actuates and the button is set on the button clamp jaw
lever.
4 The center of the button clamp jaw lever should be aligned with the center of the
button carrier. If not, refer to "6) Centering the button clamp jaw lever and the button
carrier" on p. 60.

Draw the iron core of the fine positioning magnet until
the work attachment 3 is carried to its lowest position.
Now, loosen screws 2, and adjust the screw so that
clearance R of 0.1 mm or less is provided between
the work attachment 3 and the carrier pin as long as
the work attachment 3 does not come in contact with
the carrier pin. In this state, tighten screws 2 while
maintaining the relation between vertical hook 1 and
the rotary rod.
(Caution) Open the shutter plate, and adjust the
clearance between the work attachment
3 and the carrier pin.
