Hook Timing
Hook timing is probably the most misunderstood aspect of
embroidery machine mechanics. It has nothing to do with the
type of fabric or thread tension.
Hook timing is the proper position of the hook assembly in
relation to the needle in order to form a stitch. The hook is
directly attached to the drive shaft, eliminating the need to
routinely re-time it. Re-timing of the hook only becomes
necessary due to external factors.
•
Something gets caught in the hook assembly.
•
The size of the needle is changed by more than one size.
•
An accumulation of thread behind the hook pushes the hook out of line.
The most common indication that the hook timing needs adjustment is when the machine fails
to form and complete a stitch.
Checking the Hook Timing
1. Leave the needle and bobbin threaded and
remove the throat plate.
2. Set the machine to Needle #9.
3. Remove Back Center Cover.
4. Rotate main pulley to where the indicator
points to 24 degrees. The point of the hook
should be directly behind the needle. If not,
the hook needs to be adjusted accordingly.
5. Check the hook-to-needle clearance. There
should be approximately one half to one
thread-width clearance between the hook
point and the back of the needle. Improper adjustment would cause the hook point to
miss the small loop and create a skipped stitch.
6. Replace the throat plate.
