Correct Tension Regulation

The tensions are properly balanced ifboth threads interlock in the center ofthe material. When stitching sheer fabrics, set both tensions a little lighter to Both tensions properly balanced

prevent puckering.

Upper tension too tight or lowertension too loose

Upper tension too loose or lowertension too tight.

15

Regulating the Upper Tension

Turn tension knob right to increasetension on heavier materials. Turn itleft to ease tension on lighter fabrics.The numbers on the tension dial indicate different degrees of tension.

Regulating the Lower Tension

The bobbin tension rarely needs adjusting, except for special sewing jobs. Adjustment is made by a small knurledscrew on the bobbin case.

Turn it right for tighter tensionor left for looser tension.

DR 580H 8029 16

Stitch Length Regulation

The stitch length control serves to regulate the stitch length and to limit it insewing backwards.

The numbers on the control indicate thestitch length (the higher the number.the longer the stitch). When the control is set on O’, the machine ceasesFeeding; maximum stitch length is 6 tothe inch (4 mm). To regulate the stitchlength, turn the control until the desired number is fully visible at the top ofthe slot (see arrow).

Reverse Sewing

To sew in reverse, simply press thefinger-tip control down. When thecontrol is released, the machine resumes forward sewing.

This feature is ideal for backtacking thebeginning or end of a seam and fordarning rips.

17OR 008DR 009

Fundamentals of Machine Operation

• Never run a threaded machine unless you have fabric under the sewing foot.• Place both threads back under the sewing foot before you put fabric into the machine.• Always bring the take-up lever to its highest position before you begin rind after youhave completed a seam.

• The machine will feed the material under the sewing foot automatically. All you haveto do is guide the work. Never try to hasten feeding by pushing or pulling the fabric

With presser foot No. 93-838 95OQO attached to your machine, you can start sewingnow.

Enjoy creative sewing with your Pfaff.

To exchange the sewing foot loosen thumb screw 14 (page 3). Make sure, you tightenthis thumb screw securely again.

Inserting Patches

Large holes can be patched quickly. Trim away ragged edges around the hole, cutting

a square opening exactly on the fabric threads. Cut the patch slightly larger and sew

it down (inner seam). Cut into corners, fold down raw edges and stitch along folded

edges (outer seam).

19

Zipper Insertion

R 8226

Attach edge stitcher No. 93-847 600-00 without guide. Pm or baste closed zipper on

wrong side of fabric. Position of zipper depends on whether or not you want the edge

of the fabric to overlap the zipper, Turn fabric to right side. Flun a straight seam close

to left edge of zipper, stitch across end and up the other side in one continuous operation

Use right edge of foot as a guide.

20

Hemming

Hemmer foot No. 93-847 551-00 is in

dispensable if you want to sew a uniform hem. Clip off the corner of the

fabric to facilitate insertion into the

hemmer foot. Feed fabric so that the

raw edge is in line with the left edge

of the hemmer foot opening.

Avoid ugly ends by slowing down feed

ing. To do this, press the fabric against

the needle plate on the left side of the

foot before you come to the end of the

hem.

DR 870DR 509

21

Quilting

Edge stitcher No. 93-647 600-00 used with the quilting gauge sews parallel rows of

stitching over the entire surface of the fabric. Always guide the gauge finger along the

preceding seam. Attractive tea cosies, slippers, seat pads and covers can be quilted

OR 003 22

Dropping the Machine Feed

Remove the bed cover and press thedrop feed ever down slantwise, then tothe rear and up (as indicated by the whitearrow). The lever wilt be retained in thisposition and the fabric will cease feeding.

The machine feed is dropped for darning.hoop embroidery and button sewing.

To raise the machine feed, press the leverdown and let it return to its originalposition.

23OR 855

Darning with Darning Hoops

(See page 23 for preparing your machine

for darning.)

Clamp fabric into darning hoops, cut

out small arid mediumsized holes

following the fabric grain. First stitch

back and forth across the hole with the

machine running at high speed. Then

turn the fabric at right angles and sew

back and forth over preceding work

with short stitches. This anchors threads

in the unworn area around the hole.

R 828824

Darning with Sewing FootNo. 93-839 950-00

Triangular tears, small rips or thinspots are best darned by making closestitches back and forth over the area tobe darned. To do this, attach the sewing foot and set the needle plate in thenormal position. While darning, guidethe material with your left hand and

operate the reverse feed control inrhythm with your right hand.

25 OR 559

CordingTo cord on your PlaIt 71, use a cording foot, a twin needle, and a needle p’ate with

needle plate slot.

Twin needles are available for needle distances of 1.2 (3/64”). 1.6 (1/16”), 1 8, 2.0 (5/64”).

2.5 (3/32”), 3.0, and 4.0 (5/32”) millimeters.

Cording feet are available in three varieties, as follows:

Pin tucks are made with cording foot No. 93-847 680-00 (7 grooves. 3/64” wide each)

and a 1.2-mm twin needle.

For narrow cording use cording foot No. 93-847 675-00 (5 grooves. 1/16” wide each;

see ill.) and a 1.6-mm twin needle.

Wider cording is made with cording foot No. 93-847 671-00 (3 grooves. 5/64” wide

each) and a twin needle with a needle distance of 2.0 or 2.5 millimeters.

The above-mentioned System 130 twin needles, the cording teet, and needle plate No93-113 592-00 with needle plate slot are suppliedon speciai request and at extra cost.

Changing the Needle and the Sewing

FootBring take-up lever to highest point,

loosen needle set screw a, and pull

ordinary needle out of reedle clamp.

Insert twin needle into opening of

needle clamp and push it up as far as

it will go. Make sure that the flat side

of the shank faces toward the back.

Turn sewing foot thumb screw b to the left and take out the sewing foot. Slip on cordingfoot and tighten screw b securely.It is best to turn out screw b completely if you want to slip on a cording foot with theguide attached.

Thread SizePin tucks and narrow cording are made with a No. 50 embroidery thread, wider cordingwith sewing silk in the needle and on the bobbin.Set the machine for medium stitch length.

Upper ThreadPlace a spool of thread on each of the two spool pins. Pass both thread ends throughboth thread retainer openings 2, as illustrated on page 13. Lead one thread betweenthe rear and center tension discs, and the other between the center and front tensiondiscs of upper tension 3. Raise take-up lever 4 to its highest position and pass boththreads through the hole at its end. Pull threads into slot 5, and thread each needle fromfront to back.

The bobbin thread is drawn up as instructed on page 14. To do this, hold both needlethreads in your left hand.

Thread TensionSlightly increase the bobbin thread tension, and increase or decrease the needlethread tension depending on the type of fabric used. If the tension has been Setcorrectly, the bobbin thread should appear as a faint zigzag line on the other side.

27

Filled Cording

If you want to make cording in filmy fabrics or render your cording more prominent

Pfaff recommends that you insert a filler cord. Its thickness depends on the cording

size you want.

Remove the bed slide and pass the filler cord from below through hole g located in

front of needle plate slot I (see ill, on page 26). Lay the end of the filler cord back

under the cording foot (together with

the needle and bobbin thread ends).

Pull a filler cord forward under the bed

Spacing Between Tucks

To ensure uniform spacing between

parallel tucks, place the preceding

seam into one of the grooves of the

foot and use it as a guide. For a larger

spacing between tucks, use the adjust

able guide (see ill, opposite) which is

part of every cording fot.

Two-Needle Decorative Effects

Two-needle effects can be obtained by using presser foot No, 93-838 954-00 with needleslot and a NE 1.6 twin needle. The stitch length can be set as desired. Particularly nice

effects can be obtained by using varicolored thread.

Straight-Stitch HemstitchingPresser toot No.93-838954-00 Stitch Length: Medium.with needle slot

Attach presser foot No. 93-838 954-00, and insert twinhemstitching needle, System 130 Zwi-Ho, as instructedon page 11. Turn out needle set screw a little furtherthan for ordinary needles.

The thread size, threading procedure and threadtension are the same as for cording work (seepage 27).

Beautiful hemstitching effects on blouses, dresses.handkerchiefs, doilies and so forth, can be obtainedwith Pfaff’s System 130 twin needle. The harder thefabric yarn, the more pronounced the hemstitchingwill be. Fcr this reason, batiste, organdy, georgette,etc. are best suited to hemstitching, while woollyfabrics are not recommended.
