12.2 Setting the winder
The winder is driven by its own electric motor. After it has wound the
bobbin, it switches off automatically.
Proper setting
The adjusting screw is tightened in such a way both winder levers are
approximately parallel to one another.
The winder is switched off mechanically when the winder pulley reaches
a distance of L = 8 mm from the internal diameter of the bobbin. The roller
is approx. 1 mm below the outer diameter of the bobbin.
When the winder is switched off and locked in place at its initial position,
the winder wheel is at a distance of L = 14 mm from the internal diameter
of the bobbin.
