Set The Brake Of The Film--Reel Shaft; Motor--Driven Film Unwinding (Option); Set The Film Web Tension - Bosch SVE2510 QR Instruction Manual

7 Maintenance
7.9 Film transport
7.9.4 Set the brake of the film−reel shaft
See 7.4.
7.9.5 Motor−driven film unwinding (option):
In order to determine the position of the tension arm (4), the distance between the initiator (8) and
the curve (16) on the tension arm is constantly measured. The frequency controller controls the
speed of the unwinding roller (11) in such a way, that during production the tension arm remains
in the vertical position.
ACTION
Select the unwinding direction
Set the initiator (8)
Replace and/or initialise the
frequency controller
7.9.6

Set the film web tension

Risk of injury!
When screw (2) is loosened, the spring inside the tension arm will try to release.
During the setting below a motion and/or force can be exerted on the shaft/tube (3)
that may lead to injury.
METHOD
Tie a rope in the centre of the fixed film−web roller (5) and lead the robe
over the film−web rollers backwards out of the machine; see figure.
Fasten a tension gauge (1) to the end of the rope and pull backwards
until the tension arm (4) is vertical.
If the tension deviates, firmly hold the shaft/tube (3) with a tool.
Loosen screw (2); turn the shaft/tube into the desired direction and
tighten screw (2). Clockwise turning will increases the tension.
Auxiliary driving roller with second tension arm (if provided): set the
tension of the tension arm (7) following the above method.
METHOD
Switch the appropriate switch on or
off in S−3 or level 2 (S−7−8−1)−2.
See 7.9.7.
