The planishing device according to claim 1, wherein the joint member is arranged between the joint connections of each support mean.4. The planishing device according to claim 1, wherein an end surface of the connecting element consists of a material which is attachable by way of a hot-melt adhesive to the surface of the metal sheet to be repaired.5. The planishing device according to claim 2, wherein the hot-melt adhesive comprises a polymer with polar side-group which is solid at room temperature and which softens or melts at temperatures of above 150 C.6. The planishing device according to claim 5, wherein the polymer is one out of a group of copolymer with vinyl acetate, acrylates, acrylic acid or based on ionomers.7. The planishing device according to claim 3, wherein the end surface of the connecting element is adoptable to the shape of a dent.8. The planishing device according to claim 2, wherein the pulling element is interconnected to the joint member by way of a rod and an adjusting head.9. The planishing device according to claim 2, wherein the rod is guided in a slot or in a bore so that a defined force effect is ensured.10. The planishing device according to claim 2, wherein the supporting element is a straight rail and the support means are formed as slides mounted in a displaceable manner on the supporting arm.11. The planishing device according to claim 10, wherein the support means, are lockable in a desired position on the supporting arm by way of adjusting means.12. The planishing device according to claim 2, wherein the supporting arm comprises two straight rail parts.13. The planishing device according to claim 2, wherein the pulling element is adjustably connected to the joint member in a manner such that the maximal path of the pulling element is adjustable.14. The planishing device according to claim 2, wherein the bearing elements are arranged on the supporting arm such that the foot of the bearing elements is adjustable with respect to the supporting element with regard to the distance d1 and/or angular position.15. The planishing device according to claim 14, wherein the bearing element have at least two feet.16. The planishing device according to claim 2, wherein at least one foot of the bearing elements has a fastening means which is temporarily connectable and releasable to and from the material layer.17. The planishing device according to claim 2, wherein the linkage location of the joint member and of the support means of the lever arms and the grips of the lever arms are distanced from one another in a manner such that the lever arms have a transmission ratio of at least 1:3.18. A method for removing a dent in a metal sheet material by a planishing device, comprising the steps of:a) attaching an end surface of a connecting element to a surface of a metal sheet in the region of a dent by a hot melt adhesive; b) applying bearing elements of the planishing device to the metal sheet; c) adjusting height and position of the bearing elements and a pulling element with respect to the connecting element; d) interconnecting the connecting element of the planishing device via the pulling element with inner ends of a pair of lever arms of the planishing device which are each at a distance d1 from their inner end supported in an articulated manner by a joint connection on a support mean mounted on the supporting arm; e) exerting a force essentially perpendicular onto the dent region by pressing the outer ends of the lever arms in the direction of the supporting arm such that the dent is plastically deformed; and f) releasing the connection between the connection element and the material layer. 19.
