THE PRESSURE PLATE
▲
Preliminary Remark
There is a difference between the pressure devices
on the 4-Perf and the 3-Perf Movements
THE PRESSURE PLATE ON THE 4-PERF MOVEMENT
In the centre of the front film guide
[G]
, there is an ope-
ning for the Pressure Plate
[H]
. This plate has two raised
surfaces
[a]
that hold the film in the gate plane with a
spring loaded pin. Smudged surfaces inevitably cause
film scratches! To clean the Pressure Plate, remove it as
described below:
1. Swing the pressure block [I] backward.
2. Lift and remove the Pressure Plate.
3. Check Pressure Plate and both surfaces thoroughly
and – if necessary – clean them with lint-free cloth or
orangewood sticks. Clean also the cavity at the rear
of the Pressure Plate.
The spring is pressed into this cavity. The spring-loaded
steel pin
[b]
in the pressure block presses the plate onto
the film with a certain force. When tapped lightly, the
pin should move easily and spring back to its former
position.
THE SPACER PLATE ON THE 3-PERF MOVEMENT
In the centre of the front film guide, there is an opening
for the Spacer Plate. This Plate – held firmly in place by
magnets – has raised surfaces that hold the film in the
gate plane. Smudged surfaces may cause film scrat-
ches!
To clean the Spacer Plate, it must be removed first
1. Slide the Movement to its rear position.
2. Press the safety spring fixture downwards, at the
same time pull the Spacer Plate backwards by its
handle.
3. Remove the Spacer Plate by pulling it upwards.
4. Check Spacer Plate thoroughly and – if necessary
– clean it with lint-free cloth or a toothpick. Also
clean the rear of the Spacer Plate.
