Claim 9:
10. A separator for temporarily receiving sheet elements that are to be transferred from a stacking table to an output conveyor of bundles of sheet elements, the separator comprising:
a support mounted and configured to slide in a vertical direction;
a drive device for driving the support in the vertical direction;
a plurality of arms extending in a longitudinal horizontal direction, spaced apart in a transverse direction, at least one arm of the plurality of arms being mounted and configured to move in the longitudinal horizontal direction with respect to the support, a movement of the at least one arm modifying an overhanging length of the at least one arm with respect to the support on a first side in the longitudinal horizontal direction; and
a drive system configured to simultaneously move the at least one arm in the longitudinal horizontal direction and to keep another of the plurality of arms in a longitudinal position, the drive system including:
a shaft, the shaft being deployed in the transverse direction and driven in rotation;
a pinion for each arm of the plurality of arms, each pinion for each arm rotating with the shaft;
a rack secured to the plurality of arms; and
a clutch-forming device configured to selectively couple and uncouple each pinion for each arm with respect to the rack,
wherein the clutch-forming device includes, for each arm, an actuator configured to move a pinion associated with an arm translationally along an axis of the shaft in order to selectively engage or disengage the rack with respect to the arm, and
wherein each actuator drives a corresponding lock bolt to immobilize a translational sliding of the arm during disengagement of the pinion associated with the arm.
