Foreword

Thescope of this booklet is confined to such instructions os are conditioned by

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

compared

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

ball

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

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

matching

rubber

cushions which

are

face-milled on the underside and rest on

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.

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

To facilitate the tilting bock of the sewing head without removing the knee

lever completely, the knee lever rock shaft is no longer screwed to the ongulor

sleeve, but rather held in place by a spring-loaded pin. As a result, the knee

lever can be pulled forward off the shaft with a slight jerk.

A new feature of the knee lever is its hinged foam-rubber-podded knee plate

which adapts itself well to the shape of the leg. If desired, the knee plate can

be locked by tightening a square bolt.

In replenishing the oil supply for the sewing hook, take care that no air bubble

forms in the oil line to the centrifugal switch because this would interrupt the

The simplest procedure for removing an air bubble from the oil line ahead of

is as follows:

Pull

the left end of the oil tube off the
