<2> The gap between the belt drive roller and the bead should be checked on the F side. (Checking operations

will be facilitated if a pen-light is used.)
* If there is no gap (snaking in the R direction), conditions will be as shown in Fig. 1.

The rotation control plate F should be moved one (1) unit to the left. After the rotation control plate F has
been moved, the confirmation check described in 1. above should be carried out once again.

* If there is a gap of 0.5 mm to 1.5 mm present (neutral), it is not necessary to carry out adjustments to the

rotation control plate F.

* If there is a gap greater than 2 mm (snaking in the F direction) conditions will be as shown in Fig. 4. The

rotation control plate F should be moved one (1) unit to the right. After the rotation control plate F has
been moved, the confirmation check described in 1 above should be carried out once again.

<< Adjustment Point >>

<1> If the snaking direction does not reverse or become neutral by moving the rotation control plate F one (1)

unit, the rotation control plate F should be moved two (2) units from the centre position.

<2> If, after moving the rotation control plate two (2) units there is still not change in the snaking direction, is

should be assumed that there is a problem with the transfer UN or with the machine itself, and
confirmation checks should be carried out on both.

By moving the rotation control plate F to the left, the snaking direction will change from the conditions shown in
<Fig. 1> to the conditions shown in the figure below. Furthermore, if the rotation control plate F is moved to the
right, the snaking direction will be reversed.
