3 .9 .1 Non-Driven Rear Side Take-off Friction
Generally the spring (arrow) pushes
the driving disk and the felt disk
against a fitted disk on the friction
body. The more the pressure onto
the felt disk the more braking effect
results.
This “take-off clutch” provokes that a certain traction force is necessary to wind off the
film. This friction prevents spinning of the film spool in case the projector suddenly
stops which would cause film clutter – in the worst case the film material could be
damaged or even break.

NOTE
Adjusting the mechanical friction and changing the felt disk, see chapter 6.4.10.
3 .9 .2 Electronically Controlled Fore Side Take-up Friction
The take-up friction shaft is driven by
a controlled motor (arrow).

NOTE
Z
Normally the set value is pre-
adjusted and must not be changed.
Nevertheless, if adjustments are
necessary, they should be carried
out by service engineers.
Z
Operating the frictions, see
chapter 4.4.
ATTENTION
Never use reels which have an inner diameter less than ¼ of the reel diameter
because the film tension gets too large when the reel diameter approaches the inner
diameter.
