Adjust the position of the gimp shift cam while checking the
gimp is properly sewn in.
1) If the timing of gimp shift cam No. 1 1 is excessively
advanced, the gimp will be sewn as A shown in the
illustration.
If it is excessively retarded, the gimp will be sewn as B
shown in the illustration.
Loosen screws of the gimp shift cam No. 1 1 and adjust the
timing properly.
2) Change cam No. 3 3 is likely affect the finished state of the
gimp in the manner same as the shift cam No. 1.
The procedure for adjusting the shift cam No. 3 is the same
as for adjusting the shift cam No. 1.
3) Adjust shift cam No. 2 2 so that the gimp guide finger
travels to the left stitch base line when the cam completes
one turn. Excessively advanced/retarded timing of shift
cam No. 2 2 impairs tuck-in of the gimp. Adjust the timing
of the shift cam No. 2 following the procedure described
above, then perform a test sewing and finely adjust the shift
cam No. 2 when necessary.
4) Adjust gimp shift cam No. 4 4 so that the gimp has
completed shifting from one stitch base line to another at
the time of stop-motion and the gimp guide finger travels to
the left. Shifting of the gimp guide finger to the right has to
be controlled by the gimp yoke slide block. (See #-3-(3).)
(Caution)
If the timing of gimp shift cam No. 4 4 is excessively
advanced (moves too far in the direction of the arrow),
the cloth cutting knife and the gimp guide finger may
break.
