Pfaff 238 - Pfaff 238-130 with Knee-Operated Stitch Width Control

20. Pfaff 238-130 with Knee-Operated Stitch Width Control
This machine features a knee-operated stitch width control which greatly facilitates such
operations as single-needle cording, eyelet embroidery and flat embroidery in the pro
duction of white goods, blouses, etc. (Fig. 24). A second treadle serves to raise the
presser foot.
When knee pressure is relieved, the stitch width control is automatically returned to
"0" by spring action.
On the Pfaff 238-130 the lug on the underside of pointer 2 fits snugly into notch R of
slide S (Fig. 20). For this reason, screw B must be loosened when the stitch width is to
be varied by knee action while sewing.
Screw B is tightened to lock the slide for any desired stitch width so that the operator
need not press against the knee lever continuously when sewing satin-stitch seams
with a uniform stitch width throughout, in this way, the Pfaff 238-130 can be used for
ordinary zigzag sewing, To this end, an ordinary zigzag foot with a smooth sole is
attached to the presser bar.
