8.9 Frictions. (take up and supply units)
Frictions are operated by a motor via multiple V-belts.
It may become necessary to adjust the belt tension
after a certain operating time.
To achieve this, open frame on both sides and loosen
the corresponding tension roller arms with a wrench for
5mm bolts (8mm) and adjust the belt tension.
The wind pull of the centre cores can be adjusted with
the little tension bolt inside the square mandrel (8mm)
of each friction.
For readjustment take off the film core. The tension bolt
can be turned then by an allen key (hexagon) 2.5mm
