It is known that almost all types of fruit trees have the tendency to grow steeply upwards towards the light. With such a growth, the development of the tree is concentrated on its upper part, while the trunk remains relatively thin.

The flatter a shoot or branch emanating from the trunk lies or is guided, the less it takes in volume because more side shoots are formed, i.e. it garnishes itself better. One only Experience shows that the shoot that is not very steep tends to earlier flower bud formation than a steeply standing shoot a and therefore yields a fruit earlier. It lies aaner nane, aen wucns a jtaumes not; the natural To leave development, but rather to promote the flat branch position through targeted measures. Initially this was done mainly by cutting the shoots accordingly, with the annual too strong upward shoots were cut out * Thereby only the little upwardly directed shoots remain on the tree, and the tree becomes one every year a substantial part of its growth has been taken away again. Overall, this results in slower growth and thus inevitably a later onset of earnings. In addition, each interface forms a disease danger to the tree. It also shows that the

Tree is stimulated to further strong growth by continually cutting away the new shoots, without doing so To form test wood.

The disadvantages of annual pruning led to the formation of the young trees, whereby the shoots or Branches are brought into a relatively flat position by means of aids and are held in this position as long as until the desired shape of the tree is secured. It turned out that, for example, a properly formed Kirsch IG tree in half the time, i.e. already after 5-6 years instead of 10-12 years He can be brought trac.

When using the wooden sprouts showed that the correct length is usually difficult to estimate and the attachment of the Sprouting is therefore time consuming and inaccurate. The sprouts can fall from the tree in the wind, but must be large Part of it must be reattached every year, and damage the tree at the support points. The formation of branches

with ground plugs is time consuming and requires a lot of binding material. In addition, there is a rational processing of the ground under the tree impossible. There is a risk of tree injuries when using wire scaffolding. At the wire contact points, at the side of the wire frame protruding branches cannot be formed and the wire frame prevents it from circulating freely under the tree.

The object of the present invention is therefore to create a holder for branches and twigs for forming

^ a tree in which the disadvantages mentioned can be avoided.

In particular, a holder should be created with

which the leading branches and their fruitwood shoots in an i
'; ideal angle to the central shoot or trunk of the tree

j are dressable. The holder should be used by a single person

can be installed quickly and conveniently after use

be reusable with another tree to be formed with it, require practically no maintenance and can be produced cheaply being.

This object is achieved in that a rod-shaped part contains at least one connection device to which dressing branches are releasably connectable, and that the one support device at least one the tree trunk partially encompassing fork-shaped part

contains

entnait, which frictionally engages the holder adheres to the surface of the tree trunk.

Embodiments of the invention are explained below with reference to the drawing. It shows: Fig. 1 shows a "wild" tree, whose

Branches grow steeply upwards and are long in the crown has rod-shaped branch ends,

Fig. 2 shows a tree whose leading branches and the fruit wood are at "an ideal angle to the central shoot, 3 shows a partial representation of a tree,

whose branches are pushed down to achieve a flatter course by means of devices supported on the trunk and hereinafter referred to as pipe tensioners,

5 shows a partial representation, similar to that according to FIG. 3, of a tree, the branches of which are secured against the support section of a further embodiment of the inventive device for for are drawn from trees,

6 shows, in perspective, the device used in FIG. 5 in greater detail, and FIG

Fig. 7 shows a further embodiment of the inventions ² 5-making device according to the similar structure as the

7628580 04/07/77

in the Pig. 5 and β shown.

Pig. 1 shows a tree, the branches of which flow steeply upwards towards the light in natural growth. The tree has relatively little fruit wood and contains in the upper part of the crown preferably long tails. In contrast, Fig. 2 shows a tree, the branches of which by name run less steeply in the lower part of the crown and otherwise practically evenly over the entire crown area are distributed. Such a tree shows fruit wood early on and provides a "wild" growth compared to a tree Fruits that are marketable in half the number of years. Most fruit tree species, however, have the A tendency to develop in the manner shown in Fig. 1 if nothing is done to close the branches to force a flatter growth. Three examples of devices for shaping trees are below 4, 6 and 7 shown. 3 and 5 show their practical application on a to be formed Tree.

In Fig. 3 a part of a tree crown is shown,

in which pipe clamps 1 are used to hold individual main branches. Fig. 4 shows such a pipe tensioner on a larger scale and with more details. At one end, one made up of several partial rods 2, 3 and 4 Pressure rod is a support fork 5, whose

concave opening 6 is provided for receiving the Haupttrielres or trunk of the tree or a strong secondary shoot thereof. The support fork Jj has a well-rounded support surface and is expediently made of a material that largely avoids damage to the tree bark, for example a weather-resistant plastic material. The individual rods 2-4 can be of equal or unequal length and can be plugged into one another by tapering one of their ends. Poles of any length can be formed on this Vleise.

On the partial rod 4 opposite the support fork 5, a clamping plate 7 is placed _B which is used to fix the attachment point of the branch to be dressed on the pipe clamp 1. The clamping plate 7 has a passage opening 8 through which the outermost rod element 4 extends. The diameter or the cross-sectional sForm the through-opening 8 is selected so that these _s stuck by tilting the chuck plate 7 on the rod part. 4 After the canting force has ceased, the plate 7 can be freely moved back and forth along the pipe structure. On one of its outer delimitation parts, the tensioning plate 7 contains a suspension element 12, to which a cord or band (not shown) can be tied or suspended. The cord or tape is used to attach the pipe tensioner 1 to the dressing

Another way of forming a tree with a modified form of the inventive method : direction is shown in Fig. 5, with a boom construction attached below the branches of the tree l4 is applied. Examples of such booms are shown in FIGS. 6 and 7. The ones in FIG. 5 in the working position and In Fig. 6 shown in perspective device has a practically horizontal in the position of use Carrier section 15, at whose end facing the tree trunk a support fork 16 similar to that in FIG .Fig. 4 marked 5 is attached. The beam section 15 is integrally connected to a tension strut 17, the free end of which is an open surrounding hook l8 is designed, which is intended to encompass the tree trunk 19 over part of its circumference. About the boom construction 14 are dimensionally stable., Are the dem Tree trunk 19 facing end regions of the support section 15 and the tension strut 17 with a spacer connected with each other.

which is preferably made from a light metal tube, is already after hanging a first cord on Tree fixed so that any number of additional cords can still be attached to the carrier section. As can be easily seen from Fig. 5, the support fork 16 is pressed up against the tree trunk 19 while on the surrounding hook 18, which engages on the opposite side of the tree trunk 19, a tensile force is exercised. The boom structure 14 consists of

Fig. 7 shows an embodiment variant for Lay-out structure 14 according to FIG. 6. The carrier section 25 is an I-shaped or, conversely, T-shaped light metal profile, which is attached to the trunk facing the tree End of a support fork 26 carries. On the top of the profile cord hook grooves 27 are attached, which a allow secure fastening of the cords 20 (Fig. 5). A tension strut 28 is used to transmit the on the Φ-r.äcreT'a'hartHnn-h-h?

It goes without saying that differently designed boom constructions also serve the purpose of the two described above Able to meet variants. Specifically with regard to the points of attack on the tree trunk, which are shown in the Examples have been described as pressure-exerting support forks and as tension-applying surrounding hooks,

there are design options which have not been explained and which are within the scope of the present invention.
