as the top side of the throat plate. A hook thread scissors in a too high
position may damage the fabric.
If the hook thread scissors is positioned too low, the hook threads are
not cut off.
The limiting sheets 3 fastened at the cylinder 5 determine the opening
width of the spring clamping sheets.

tips must move by with a safe distance.
