Pfaff 467 User Manual

36. Timing the Top Feed
When checking, and possibly retiming, the top feed motion, keep in mind that this motion
must be timed in relation to the dwell of the feed dog.
The motion of the vibrating presser should be reduced to 0 shortly after the needle bar has
passed the top of its stroke.
According to the instructions contained in Chapter 35, the feed dog was set to make no
perceptible motion when the needle bar has passed the lowest point of its stroke and risen
about Vas", or 0.6 mm. Before synchronizing the top and bottom feeds, rotate the balance
wheel until the needle bar has just passed the highest point of its stroke, set the machine for
its
longest stitch, and check to see that the feed dog makes no perceptible motion when
you operate reverse feed control p.
With the feed dog at this position, loosen set screws 9 and 10 (Fig. 43) and rotate top feed
driving eccentric OS until the vibrating presser makes no perceptible motion when the stroke
of the feed dog is reduced to 0.
To facilitate rotating the top feed driving eccentric on the arm shaft, insert a suitable punch
into the hole of the eccentric and hold the balance wheel steady as you rotate the eccentric
to synchronize the dwell of the vibrating presser and of the feed dog. After the adjustment,
tighten set screws 9 and 10 securely.
