4.3 Threading and thread courses
A T T E N T I O N ! Danger of bodily injuries
Switch off machine electrically and confirm that the
machine is really in standstill position by operating the
treadle for the motor control before threading.
Otherwise danger of finger bruises and needle through
stitches.
CAUTION!
The function “Preparation threading” does
not
replace the electrical switching off of the machine during
threading.
This function serves only to ensure that the needle is
already in the correct position when the machine is
switched off.
4.3.1 Threading
Before the actual threading of the machine, the needle point can be brought
into the correct position with the function “Preparation threading”.
The function is activated or deactivated by the button “4” on the V810 operating
control and displayed with an arrow over the button or otherwise with the
“-Stop-” display in the display.
Please see the operating instruction manual for the sewing drive.
4.3.2 Thread courses
Because of the pneumatically controlled gathering device two successive
Asked thread tensions are grown. The front tension 838.0196 operating
normally, the rear thread tension 938.0196 activity occurs when the partition
plate of Gathering device swung and fullness, as is gathered at the toe. For this
shirring a firmer tension is needed to better fix the resulting material folds on
the shoe sole, and can get a good gathering. After swinging the partition plate,
the front is now more normal tension back into activity and that the rear thread
tension is released.
