Jute fabric and plastic film are known as wrapping materials and more or less large pot-like containers made of plastic, etc. Μεη has also tried wire-like Use braids such as the braid with hexagonal mesh known under the warning chicken wire. That Balling up by wrapping it in a fabric or in the aforementioned wire mesh causes a lot of work and is cumbersome and time consuming and also poorly suited for larger root balls. The hexagonal wire mesh leaves only cumbersome to shape into a basket. In addition, this results in folds that protrude in particular Way to be attached or cut away. Balling in the root ball takes almost the same Time like digging out the root ball by hand.

For digging up trees and the like, it is known that the root balls of trees and bushes are excavated, preferably in tree nurseries, with the help of an excavator-like device. By the predetermined size and shape the gripper of the device achieves a predetermined uniform size and shape of the excavated root ball. This leads to a saving in labor costs for digging the trees and the like with the root ball. For balling the dug up root ball and the preparation of the tree for transport, especially at Trees and bushes with a relatively large root ball, the diameter of the size of about 40 100 cm, a considerable amount of personnel and work is still required. This will make mechanization the excavation of the root balls of trees and bushes is still very much affected.

The object of the invention is to provide a balling basket from wire mesh for root balls of trees, bushes, etc. to create a pre-formed, dimensionally stable Has shape and is free of folds on the peripheral surface and can be stacked, with a simple and quick production results. The balling basket made of wire mesh is characterized in that the wire basket made of welded wire mesh with rhombic mesh shapes and loosely running along the wire mesh Edge wires, its perpendicular to the edge wires running edges overlap somewhat and one edge of which is provided with an edge wire except for one Remaining opening is contracted and the other edge of the wire mesh provided with edging wire an opening of has a size at least equal to the diameter of the root ball.

By using a welded wire mesh with rhombic meshes lying in the longitudinal direction of the track, in which the wires running diagonally to the mesh web are welded at the crossing points, with the Edges of the net web one or more wires or the like. run through the closed side loops of the net, there is the advantage that the welded wire mesh can be deformed to form a dimensionally stable wire basket with an approximately spherical bottom half. The wire basket with the spherically curved bottom surface is completely wrinkle-free. By pulling together with the edge wire, only the rhombic shape of the mesh changes, in that the meshes progressively merge into an elongated acute-angled shape towards the apex of the spherical shape. In the case of the wire basket, this has the advantage that the wires of the mesh are close to one another in the region of the apex surface

come to rest. This will make the soil of the root ball held together favorably at the lower surface of the balling wire basket, so that by itself the design of the wire basket made of welded wire mesh with rhombic meshes holding together the in the Wire basket inserted root ball is favored considerably. The wire basket according to the invention also has the The advantage that the free opening of the wire basket, which is adapted to the diameter of the root ball, after the insertion of the Root ball can be pulled together by the edge wire located at the opening so that the upper half of the wire basket gives an approximately hemispherical shape so that the root ball is also in the upper half is wrapped in a spherical shape by the wire basket. In this way a firm enclosure of the root ball is achieved. The root ball is, as it were, in a spherical covering made of wire mesh all around included, so that the tree or shrub by grasping the wire basket, preferably on the edge wire encompassing the tree trunk, can be transported. The baling wire basket according to the invention enables the root ball to be packaged quickly and cost-effectively for transport. The preformed, The wire basket open on one side also enables the preformed balled wire baskets to be stacked one inside the other and thus also a space-saving supply and transport storage. The mesh size and the wire size can be adapted to the predetermined size of the bale and its dependent weight will.

The production of the balling wire basket according to the invention is advantageously carried out in such a way that a right
