Setting The Bobbin Housing Lifter; Setting The Lifting Gap - Dürkopp Adler 567 CLASSIC Service Manual

Setting the bobbin housing lifter

12 Setting the bobbin housing lifter
Fig. 32: Bobbin housing lifter
The hook pulls the needle thread through between the nose of the spool
housing (3) and the recess in the throat plate (4).
The bobbin housing lifter (2) now pushes the bobbin housing (1) away so
that a gap appears for the thread.
If the hook tip is located below the bobbin housing lifter, then the bobbin
housing lifter 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 set.
Faults caused by an incorrect setting:
• Thread breakage
• Formation of loops on the bottom side of the seam
• Loud machine noise

12.1 Setting the lifting gap

Order
Always check the width of the lifting gap after making changes to the
needle thread size. The correct width of the lifting gap depends on the
thickness of the needle thread.
