27. Timing the Hook
With the PFAFF 3114 the amount of needle bor rise required to form the
loop is (2,4 mm), i.e. when the needle has passed the lowest point of
its stroke end risen the point of the hook should be just opposite the
center line of the needle and about (2.0 mm) above the top of the
needle eye. This distance is checked when the needle
ascends on its right
hand stroke while sewing the left parollel of the buttonhole.
The needle bor rise can be easily adjusted with the aid of the gauge which
may be obtained from us.
Begin by lowering the needle bar to the lowest point of its stroke, push
the gauge a (Photo 31) on the needle bar immediately below the
needle bar frame, push the clamp on the needle bar immediately below
the gauge and screw it on.
Remove the gauge and turn the driving pulley slowly until the clamp strikes
the needle bar frame.
