9.7.3 Sequence of Movements of the H and Z Jaws Levers

Please refer to the following diagram as you read the description of the sequence of movements in the

centering procedure.

Fig. 9.7.6 Sequence of movements of the h and z jaws levers

9.7.3.1 Sequence of Movements

1. The direct current servo motor moves the toothed rack and the toothed strip support towards the segment.

Here the h and z claws slide on the guide shaft towards the segment.

2. The deep-grooved ball bearings of the z jaws lever slide along the 45° incline of the z claw. The z jaws

close. At the same time the h jaws carry out a longitudinal movement until they are at the same height as

the z jaws.

3. The h and z claws move further on towards the segment. As soon as the z claw reaches the stop - that is,

the z jaws have closed to the defined separation - the closing movement of the h jaws lever begins.
