TIMING THE NEEDLES TO THE LOOPER (CONT.)

FIG. 9
FIG. 9A
FIG. 10
Attach the looper clamp and height gauge (A, Fig. 9) to the heal of
the looper by tightening screw (B). Turn the handwheel slowly in a
clockwise direction until needle bar (C) touches stop screw (D).
Loosen screw (E) and set synchronizing gauge rod (F) so the flat end
is on one of the lines in the center of the block (G). Tighten screw
(E).
Turn the handwheel in the opposite direction until the needle bar
(C, Fig. 9) or gauge block (Fig. 9A) touches stop screw (D, Fig. 9).
Synchronizing rod (F) should come to the same line on block (G).
The difference must not exceed one line.
If the setting cannot be achieved, main shaft coupling (A, Fig. 10)
must be repositioned.
gasket. Loosen the three coupling screws (B). If synchronizing rod
(F, Fig. 9) moves more to the right while the handwheel is rotated in
a clockwise direction, the looper is too fast and the main shaft
should be retarded. If the rod moves more to the right when the
handwheel is rotated in a counterclockwise direction the looper is
too slow and the mainshaft should be advanced. Tighten screws (B,
Fig. 10).
NOTE: If the stationary Knife interferes with the synchronizing
rod (F) remove the knife to make the adjustment.
