Switching The Needle Bars On And Off - DURKOPP ADLER 381 Operating Instructions Manual

6.13 Turning the Needle Bars On and Off
The needle bars can be turned off with lever 1.
The position of lever 1 determines which needles are working:
–
Lever 1 in the left position.
Left needle bar turned off (right needle bar is working).
–
Lever 1 in the right position.
Right needle bar turned off (left needle bar is working).
–
Lever 1 in the middle position.
Both needle bars are working.
The needle bar is arrested in its high position. The lever 1 must therefore be operated
in standstill (down) or during the upward movement, before the needle bar lies 3 mm in
front of its high position.
If switching occured too late, then the handwheel must be turned back a suitable
distance. During the subsequent forward turn the needle bar is then arrested in the high
position.
Turning the switched-off needle bar on again:
–
Press switch 2.
The lever 1 moves into the middle position by itself.
The switched-off needle bar is turned on again. It follows the working needle bar
when this has reached its high position.
The switch must be operated in needle low position or during the upward movement so
that the switched-off needle bar can follow the working needle bar by the next stitch.
If switching occured too late, then the handwheel must be turned back a suitable
distance. During the subsequent forward turn the needle bar is coupled in.
