Pfaff 360

The loop taker used in Pfaff 260 (360)- 261 domestic sewing machines is the
type
of sewing hook described under b. above. It is a sewing hook of Pfaff's
own design which
is rated as jam-proof. Mounted on a horizontal shaft, this
new Pfaff hook (Fig.
15) is set transverse to the direction of feed and moves
counter-clockwise, making two revolutions for each stitch. In other words, a
stitch
is formed only at every other revolution of the sewing hook, which is a
favorable ratio for the take-up lever motion.
