19.8.SPREADER PHASE
The purpose of this eccentric is to move the comb of the spreader in synchrony with the movement of the needle and
with the movement of the looper.
19.8.1.POSITION
To place correctly the eccentric of the starting of the spreader movement place the Needle Bar to the following Phase
point.
Rotate the wheel until the thread exit hole on the upper part of the loop crosses the center line of the needle, with the
Needle Bar in descent.
At this point the eccentric is with the fixing screws in the following position, the first screw in direction of rotation perfectly
vertical while the second one is perfectly horizontal as represented in the picture below:
Furthermore, check if there is absence of play between the eccentric and the left shearing, block very well to avoid bad
working and oil leaking from the eccentric seals.
