4. Handling device according to claim 3, wherein at least the sliding elements (20) of a closing unit (25) are coupled in motion to a common drive mechanism (30), wherein by the sliding elements (20) of the closing unit (25) in each case an opposite movement is feasible or the sliding elements (20) of all closing units (25)

motion-coupled to a common drive mechanism (30) are arranged, wherein by the sliding elements (20) of a closing unit (25) each have an opposite movement is feasible and wherein by the directly adjacent sliding elements (20) adjacent closure units (25) each have an opposite movement is feasible ,

5. Handling device according to claim 3 or 4, wherein the drive mechanism (30) comprises at least one arranged on a drive means revolving conveyor having an upper run (31 o, 32o) and a lower run (31 u, 32u), wherein one of the sliding elements (20). a closure unit (25) on the upper run (31 o, 32o) of the conveyor is arranged and wherein the other sliding element (20) of the closing unit (25) on the lower run (31 u, 32u) of the conveyor is arranged.

6. Handling device according to claim 5, wherein the drive mechanism (30) has two parallel, via a common drive shaft (35) on the

The sliding elements (20) are each arranged between the two conveying means and are respectively fastened to both conveying means, in particular wherein the sliding elements (20) alternately on both sides of the upper run (31o, 32o) both conveyor or bilaterally on the lower run (31 u, 32u) of both conveying means are arranged.

7. Handling device according to claim 5 or 6, wherein the drive means a

Servo drive (33) and / or wherein the at least one circulating conveyor is a toothed belt (31, 32).

8. Handling device according to claim 4, wherein the sliding elements (20) of all sealing units (25) each have their own drive, wherein the

Drives via a control device (40) are driven in such a way, each of the sliding elements (20) of a closing unit (25) respectively

are oppositely movable and / or the respective adjacent

Sliding elements (20) of adjacent closing units (25) in each case
