5.1 Measuring and Adjusting the Winding Torques
The rewinders for the transfer ribbon are coupled to slipping clutches in the main drive. The supply hubs of the
transfer ribbon are braked with a slipping clutches during printing.
The correct setting of the torques of these slipping clutches is necessary for:
• precise conveyance of the transfer ribbon during label transport
• the prevention of wrinkles in the feed path of the transfer ribbon
If the winding torque differs from the set value, it must be adjusted. 5.1.2 on page 21.
5.1.1 Measuring the Winding Torques
Measurement of the winding torque at the transfer ribbon take up and supply hub occurs by determining the pulling
forces on a test collar attached to the winder.
The physical relation between the torque and the pulling force is:
F= M / r
F: Pulling force [N],
M: Winding torque [Ncm],
r: Radius of the test collar (30 mm)
