  • a rotation angle clearance can for example be between 10 ° and 360 ° or between 30 ° and 180 °.

This achieves damping and prevents the second part roller from turning back excessively fast.

  • one or more gas springs may be provided, which is operatively arranged between the sub-rollers of a pair of rollers or are.
