The leading jack slider (4) is switched upward.
This pivots the holding-down jacks downward into the holding-down
position during needle raising. They hold down the stitches.
The following jack slider (5) is pulled back and the holding-down jacks pivot
back again. The holding-down jacks are open during yarn insertion.

automatically.
