Pfaff offer the only househo ld sewing machine in
the world with built in dual feed. By this means, the
material is not only fed from below, but also from
above simultan eously. During processi ng of long
fabric panels, such as curtains and side curtains,
etc., there is no shifting of the material plies.
Also during assembl y of checked or striped fabric
panels the material is fed exactly by the dual feed.
Especial ly during processi ng of delicatee mate
rials, no seam pucker results. In the case of pla
stics, oilcloth, imitation suede, etc. (i.e. in the case
of extremel y difficult material s), dual feed is an
equally great help. It provides for excellen t feed
ing of your workpie ce, and consiste nt seams. The
dual feed can be combine d with several sewing
feet.
To engage:
raise sewing foot, push top feed
downwa rd until it engages.
To disengag e: lift sewing foot, press top feed
lightly downwa rd, pull it to the rear
and allow it to move up.
