The little rod 7 is displaceable by means of a piston-cylinder device which is identical to device 22. The little rod 7 cannot emerge from the U-shaped profile part because the part 25 on its open side with one another directed ribs 27 is provided, which are supported by the side surfaces 2 (.

To facilitate the picking up and collecting of the fruit falling on the second sheet or net 4, i.e. the zone in which the fruits falling on the second cloth or net jump down from this cloth or net 4 can, means is provided to lift at least one corner of the second cloth or net 4 and preferably to lift one of the two corners defined by the ends of the rod 5.

Fig. 4 shows an embodiment of a device for lifting a corner of the second cloth or net 4, and more precisely, for lifting one of the two corners defined by the ends of the rod 5.

As shown in Fig. 4, the means for lifting comprises one end of the rod 5 and thus a corner of the sheet or network 4, a piston-cylinder device 28, which has a cylinder 29 and a piston 3o, of which the latter a piston rod 31 protrudes. The end of the piston rod 31 protruding from the cylinder 2 is connected to the base of the U-shaped profile part 15 securely connected.

To pick up and collect the on the second cloth or net 4 falling fruits and the unwinding and winding

030036/0698

of the second cloth or net 4 on the rod 5 to facilitate, a modified embodiment can be used, which is shown in Fig. 7 in plan view.

As shown in FIG. 7, this modified embodiment differs from the embodiment described above only due to the special shape of the second cloth or net, which is denoted by 32 here. The second cloth or net 32 has the shape of a right-angled trapezoid, and the side that with reference to the base runs obliquely, is provided with one or more protruding ribs 33.

All other elements and components of the embodiment according to FIG. 7 are the same as previously in connection with the first embodiment have been described.

By introducing compressed air or another Pressure medium in the pockets 14 results in a rolling of the roll 3 on the ground, which in turn results in an unwinding of the first cloth 1 from the roll 3 results. The first cloth 1 is placed here on the ground.

030036/0698

Μ-

As a result of the roll 3 rolling on the ground, the cylinder 9 drawn by the roll 3 rolls on the first cloth 1, since the cylinder 9 is connected to the roller 3 via the frame Io, whereby through the frame Io over the profile part 25, the rod 7 carrying one end of the second cloth or net 4, indirectly with the roller 3 and is connected to the cylinder 9.

Wraps during the operation described above the second cloth or whet 4 from the rod 5, the springs arranged in the rod 5 being placed under tension will. This results in the state of the device as it is shown in Fig. 1 and in which the second cloth or net 4 is located above the first cloth 1, but without touching it.

At this point in time, the device by means of which lateral displacement of the second cloth or net 4 with respect to the first cloth 1 is caused, driven. This device is shown in FIGS.

The said device is driven in that pressure medium is fed into the piston-cylinder devices 22 which move the prismatic rod 18 or the small rod 7 by placing them in the U-shaped profile part Move 15 or 25.

At the end of this work process or during the work process, the device is also driven by means of which a corner of the second cloth or net 4 is lifted. More precisely, that corner of the cloth or net is 4 lifted, which is located at that end of the rod 5, which is closer to the tree trunk. The piston-cylinder device is used for this purpose 28 actuated, which means that pressure

030036/0698

means is guided into the cylinder 29 in order to move the piston 3o and the piston rod 31 according to FIG. 4 upwards. As a result, the relevant end of the rod 5 is also moved upwards.

At the end of all the operations described above, the device is in a state in which the second cloth or net 4 is pressed over a short length against the tree trunk and in the direction against the contour of the device runs obliquely, which is further away from the tree trunk. The on the second cloth or net 4 falling fruits are brought towards the corner due to the inclined position of the second cloth or net 4, which is further away from the higher corner of the cloth or net 4, and in this way one results Concentration of the fruits lying on the cloth or net 4,

Completing the picking and collecting of the Fruit arises during the contraction of the device. This contraction takes place by means of the operations instead of those previously described for the extension, but with the operations involved in opposite directions Direction, which means that the last operation described when expanding or spreading the device when contracting the device is the first operation. Thus, the device will contract the pressure medium is discharged from the flat channels 14, after which the first cloth 1 under the action of the strip-shaped Coil springs 11 tends to wind up on the roll 3. Here, the bogie 8 is on the first Cloth 1 according to FIG. 1 moved from top right to bottom left. During this movement, the first cloth 1 is on the roll wound up.

Fig. 8 is a perspective view of part of the first cloth 1, and from this view are the arrangement

030036/0698

the strip-shaped spiral springs 11 and the elongated flat channels 14 can be seen. As "mentioned earlier, is located When the first cloth 1 is spread out, the side on which the channels 14 are formed is in contact with the ground.

Thus, when the first cloth 1 is wound onto the roll 3 in the manner described, at the same time the second cloth or net 4 is wound onto the torsion bar 5, under the action of those arranged in the torsion bar 5 Feathers.

From the above description it can be seen that the set objects are achieved by a device according to the invention will.

For example, it can be seen that according to the two superimposed towels 1 and 4, the falling Fruits cannot be soiled, since the cloth or net 4 on which they fall never touch the ground is in contact.

Furthermore, since the entire ground under a tree can be covered with two devices according to the invention, a loss of falling fruit is completely avoided, so that. the fruits are practically one hundred percent collected can be.

Finally, it should be noted that by using a cloth 1, which is rolled out on the ground can be and on which the actual collecting cloth moves, it is possible to use the device according to the invention to be used on any type of soil and in any condition of the soil.

030038/0698

Various changes are within the scope of the invention possible. In particular, it should be understood that the positions of the rod 5 and the rod 7 are interchanged can.

It is also possible, instead of the pressure medium devices 22 or 28, to move the second one laterally Cloth or net 4 or for lifting a corner of the second cloth or second net 4 corresponding mechanical devices to use, for example, gear and rack equipment.
