(5) Clearance Between Shuttle and Shuttle Driver
The clearance gap between shuttle and shuttle driver should be wide enough
to permit the heaviest
grade of thread used on this particular machine to
pass through it freely. A clearance of obout V64", or 0.4 to 0.5 mm,
normally will be sufficient for this purpose. To
allow heavier threads to be
used on this machine, it may be necessary to make this gap about V32",
or 0.6 to 0.7 mm, wide.
If adjustment is required, bend the driver fingers cautiously, making sure,
however, that the bottom finger does not contact the shuttle race and the
top finger is positioned exactly
opposite the center of the shuttle neck
(Fig. 25).
