The hook pulls the needle thread through between the nose of the bobbin
case (3) and the slot in the throat plate (4).
The bobbin case lifter (2) now pushes the bobbin case (1) away so that a
gap appears for the thread.
If the hook tip is located below the bobbin case lifter (2), the bobbin case
lifter (2) must open so that the thread can also slide past in that position.
So that the thread can slip through without a problem, the width of the
lifting gap and the timing of opening have to be adjusted.
