Also, swing levers are pivotally connected, one at each end, to the spindle of the first intermediate roller and each swing lever has guides for guiding the second intermediate roller between its first position as a connecting roller and its second position as a tandem roller laterally below the first intermediate roller and in engagement with the applicator roller of the damping unit.
