Abstract
A method and device for reducing the maximum torque to rollers mounted on a drive shaft of a drive roller assembly. By using a plurality of slip clutches, each for engaging an individual roller to the drive shaft and setting a maximum torque for the individual rollers, each roller is coupled to the drive shaft when the tangential force exerted on the roller does not exceed the maximum torque, and each roller is mechanically decoupled from the drive shaft when the tangential force exerted on the roller exceeds the maximum torque. Because each roller has a separate slip clutch, each roller can be mechanically decoupled from the drive shaft without affecting the other rollers coupled to the drive shaft.
