2.9.3 Adjusting the gripper (figure 8)
At the moment when the loop is picked up, the gripping finger must lie
0.1
–
0.2 mm above the needle. This must also be observed when changing
the needle thickness. It is essential to prevent needle contact from occurring!
The horizontal distance from the large gripping finger to the eye of the needle
should be 1.5 +0.5 mm
(figure 8) . On the left side where the loop is released,
the needle must pass centrally in between the two gripping fingers. These
values can be adjusted by turning and moving the adjusting cam
(6) figure 6
and rotating the gripper shaft against the head of the connecting rod
(3) figure 5
.
Check the gripper movement by carefully turning the main shaft using the
handwheel!
Check that all fastening screws are firmly installed!
