Foreword

Thescope of this booklet is confinedto such instructions os are conditioned by

voriotions in the design of the new Pfoff 463 high-speed sewing machine as

compared

with previous Pfaff high-speed seamers.

An outstanding feature of the Pfoff 463 is the incorporation of seaied-for-life

ball

and

needle

bearings

of the latest design which

obviate

the use of an

automotic lubrication system.

Another salient feature is the arrangement of the feed driving and feed lifting

eccentrics

the

bottom

rather

than

the

arm

shoft.

The

bottom

shaft

driven

from the arm shaft by a Synchroflex belt

and

drives the hook shaft by means

of helical

gears.

These driving elements

are

enclosed in an oiltight

gear

case

and

are

lubricated

by means of an oil-soaked foam rubber sheet. The only

part

that requires

special lubrication is the sewing hook. Lubrication of this port is accomplished

by means of a reservoir oiling system incorporating acentrifugal switch.

Since

the

arm

shaft

belted

the

motor,

the

machine

can

tilted

bock

without removing the V-belt.

Additional features of the new high-speed seamer

are

a novel stitch length

control,

separate

forward-reverse feed control, built-in bobbin winder

and

built-in lifting lever.

Operators will like the modern functional design and the streamlined belt

guard

which is

attached

to the machine arm.

1. Setting Up the Machine

The Pfaff 463 drop-feed sewing machine, like the other models in the new

line of high-speed seomers, con be set up only on o power table fitted with

the new rubber hinge bracket

and

cushion set.

The front corners of the bedplate

are

face-milled on the underside and rest on

matching

rubber

cushions which

are

recessed into the

tabletop.

At the back, the new-type hinge studs connect the sewing head to the pins in

the two rubber hinge brockets. This mounting prevents the machine from com

ing in contact with the tabletop.

The machine is carefully balanced and causes procticatly no vibration. What

ever vibration there is,will be absorbed by the rubber hinge brackets.

2. Mounting the V-Belt

The machines ore shipped with the belt guard removed.

To mount the V-belt, lift the sewing head slightly and place the belt on the

machine

and

motor pulleys.

Slightly turn out screws

ol,

a2, a3, and a4, and push the two belt guard

sections together, holding them close to the machine so

that

the

above

screws

enter the appropriate slots in the back wall of the belt guard.

Fig. 2 R8608

To tighten the screws again, insert the screwdriver through openings

bl,

b2,

b3,

and

b4 (Fig. 2).

Both belt

guard

sections

ore

secured

to the vertical portion of the machine

arm

by inserting screw d (Fig. 1) through holes b5

and

c into screwhole dl

and

tightening it securely,

3. Test-Running the Machine

Before you tesf-run the mochine, carefully remove all dirt which may have

accumulated in transit. Use only abrush

and

acleaning rag for this purpose.

The

Pfoff

463

must

never

rinsed

cleaned

with

kerosene

because

there

donger

that

the cleaning fluid enters the sealed-for-life

bearings

and

dis

solves the greose. For the

same

reason,

kerosene or gasoline must not be used

for the

regular

servicing of the machine.

Never attempt to eliminate hard working of the machine by squirting oil freely

into the bearings which, you believe, may be responsible for this fault. If oil

enters the sealed-for-life bearings, the grease will be thinned

and

flung out of

the

bearings,

thus eliminating

permonent

lubrication.

4. Winding the Bobbin

The new high-speed seamer is fitted with a bobbin winder which is incor

porated in the face cover rother than mounted at the balance-wheel end, as

customary. Arranged at a convenient height, it is easy to operate end enables

the operator to wind bobbins

quickly

and neatly.

The bobbin winder driving

motion

emanates from the take-up crank. When the

bobbin winder is engaged, driving crank F at the rear end of spindle 17 is

pushed into the circular path of stud K which engages the crank and in this

way drives the bobbin winder (Fig.3).

The bobbin winder spindle is carried in a self-lubricating sinter-metal bearing

which requires no additional lubrication. To

engage

the bobbin winder, simply

depress stop latch a located above the bobbin winder spindle (Fig. 5). This

action causes the spindle to move slightly to the right in which position it is

retained

until

sufficient

thread

has

been

wound

the

bobbin.

The

thread

wound on the bobbin pushes the com up

and

thereby stops the bobbin winder.

The

amount

thread

to be wound on the

bobbin

can be

regulated

by loosen

ing screw b and setting cam a higher or lower, as may be required. Set the

cam higher for more

thread,

or lower, for less

thread.

Figs. 4

and

5show how to

guide

the

thread

to the

bobbin

winder.

Place the spool of

thread

on spool pin 11

and

bobbin 16 on spindle 17. Lead

the

thread

from spool

and

through the top

thread

guide

of the threod

stand,

down

thread

guide

12 on

the

rear

arm

cover,

through

thread

retainer

13 below thread guide 2, through thread guide 14 and around thread tension

bobbin

16.

PFAFI

Fig. 5 R

To facilitate

threading,

if is

recommended

to wind a few clockwise turns on the

bobbin 16 first,

and

then to lead the

thread

around

thread

tension 15. Depend

ing on the material to be sewn, the

thread

should be wound tighter or looser.

From the library of: Superior Sewing Machine & Supply LLC

The thread tension is regulated by turning thumb nut 18 back of the tension

discs. Turn

the

nut

counter-clockwise

for a

tighter

tension,

or clockwise for a

looser

tension.

If the threod should pile up

one

end

of the bobbin, adjust the position of the

tension stud. The set screw securing this stud in position can be reached from

below.

5. Threading the

Needle

Because of the high speed of the seamer the smooth possoge of the thread to

the needle is especially importont.

Lead the thread from spool pin 1 up to the top thread guide of the thread

stand and down to thread guide 2. It is recommended to lead the thread first

through the vertical hole from top to bottom and then through the transverse

hole of the guide, as shown in Fig. 4 and 5, in

order

to prevent it from snarl

ing up on the guide and breaking,

Now lead the thread through two or three holes of thread retainer 3, as may

be required,

clockwise

around and between tension discs 4, through thread

check spring 5, under stock threod regulator 6, through thread guide 7, from

right to left through the hole in take-up lever 8, through thread guides 7 and 9

and from left to right through needle eye 10.

6. Regulating the Stitch Length

The stitch length is regulated by means of stitch length control n

(Fig.

6). The

large diameter of this control

mokes

for an exceedingly fine

stitch

length

regulation. When control n is turned by one tooth, the

stitch

length is increased

Vfii".

The stitch length is indicated on the teeth in millimeters.
