1. Timing between the looper and needle bar (synchronization)
Gauging equipment is mounted to perform synchronization adjustment.
The reference state is that there is no clearance between the bottom surface of the lower needle bar bushing
and the top surface of the timing gauge
when the steel rod
touches the throat plate
by rotating
the pulley in the forward and backward directions. (Be sure to rotate the pulley in both directions to check the
clearance.) The allowable clearance range is from 0 to 0.1 mm.
(Caution) The allowable clearance between the steel rod
and the throat plate
ranges from 0 to 0.1
mm when the bottom surface of the lower needle bar bushing
touches the top surface of
the timing gauge
ahead of the other touch by rotating the pulley in both directions.
(2) Timing between the looper and needle bar
19mm
Clearance at rotation in both
directions: 0 to 0.1 mm
