Setting the braking torque
The braking torques of the foil mandrels can be set by
turning the red hexagon on each mandrel. Turn clock-
wise to increase the torque.
The traction exerted on the foil is in proportion to the
winding/unwinding torque. To set the braking torque,
measure the traction with a spring balance.
Tools:
• Spring balance 50 N (Article number 93665-00-0)
• Cardboard core of a ribbon roll
Setting range for the tractive forces on rewind and un-
wind mandrel:
Measuring the tractive force
1. Push a cardboard sleeve on the ribbon mandrel.
2. Wind some fabric ribbon around the cardboard
sleeve.
3. Fix the end of the fabric ribbon [49B] to the spring
balance [49A].
4. Pull constantly at the spring balance until the ribbon
mandrel starts to turn [49]. At the same time, read
the tractive force from the spring balance.
While measuring the
ribbon rewinding mandrel
,
you must block the print roller (hold it manually).
