Plants not hindered. To this Z./.'eck from the start Providing larger openings is disadvantageous, mainly because of this the purpose of covering ira germination stage impaired will.

The fulfillment is based on the task of creating a slide of the initially characterized to create with the allow the desired various degrees of coverage to be realized.

This object has been achieved according to the invention in that the film is provided with many non-closed, bottom polygonal incisions or linear cuts, which form flaps which can be pivoted about the connecting straight line of the cut end points belonging to the same cut. This ensures that the film guarantees practically 100% coverage when the flaps are closed and offers any degree of permeability by opening the flaps to different degrees Exercise the flaps swiveling straight. This is especially the case when young plants are growing, the flaps of which open openings of continuously increasing size after their progressive growth. This means that the

sweito guaranteed.

The flap film according to the invention is loud for the jirsielum ;. take advantage of the most varied './irkun^en. For example, by providing the film with rectified flaps läiät üie at Auslejun ^ on a slope with downwardly ^ ericlrceten Klaj ^ s for derivation of water use, et; to an excessive irrigation of the sub M to prevent "a their underlying soil or rainwater bevorzujt hanjamiärts lying positions forwarded to Uiii .. ^ ekelirt can .Verle by ^ the film UNJ with han _c upward flaps one ot; ei;. erunj irrigation a »; Han _{o- be} scored.

The film can also be designed to be independent from their Neijunj a jleieh jute permeability von "Kejemiasser has by adding them to flaps facing different sides.

Simple angled ones can be used to form the flaps Incisions may be provided. These become appropriate practically no material removal is generated, so that the Flaps in the closed position have a practically no slot VerscliluS surrender.

drive that in each case from a middle point of the to be generated Starting the cutting line, cuts are made in opposite directions at the same time and that the film is displaced transversely to the cutting direction.

A simple device for producing the films can be achieved in that knives are provided, their & Cut in a plane perpendicular to the foil accordingly runs in a curve or polygonal manner and that furthermore a feed device is provided for the film, which moves the film transversely to the plane of the knife edge during the cutting stroke. V / i 11 one thereby rectified flaps produce, the film is always left in the same direction run, while by advancing the film in "alternating directions" correspondingly differently directed Flaps forms.

but can also be used for a wide variety of other types. Another important area of application is, for example given in drainage systems, where the film can serve to cover the Di'änstränge. The flap foil offers the main advantage here that it is in the closed Flap position that changes after laying

in the drainage ditch will not or hardly change even after a long period of time, although it offers an excellent passage for water , the penetration of solids in the drainage pipe, on the other hand, offers a consistently good resistance. In this way, premature blockages of the drainage pipe and in particular of its filter cover can be avoided. Also as a cover for filter layers in ™

The flap film can be of great service to well systems.

Another important area of application is the covering of products that are at risk of corrosion, for example machines, for transport and storage and for the production of food packaging.

For coverings for different purposes, it is sawn A known, films with a layer of straw or the like fibrous connect to a cover sheet to. The connection is usually made by stitching the film together with the fiber layer. If a film according to the invention is used for this purpose, the lock stitches result in a perforation and thereby a film with openings which consist of a combination of flap openings according to the invention and the per se known perforation.

The machine used for the production of the flap cover consists essentially of a supply drum 1 £ i £ e l 'for the plate, unpainted foil 2 used to produce the Klaijpen foil, a pair of orphans 3i ^> which is provided to put the foil in the cutting station under ^ To maintain a certain tension, the 3 cutting station with a periodically moving up and down knife bar -j with two- Kesserreihea ΰ, β, a second on the side of the ο without identification arranged V / roller pair ο, 9 with the drive of the V-roller 9 by a motor 10 and a take-up drum 11 for the finished flap band.

If the Hesserbalken -j is vertically up- and a, then the sliding of the foil through the 3ohneidstation is carried out step by step. Leg up to ^ ^ ä Hesser- the beam takes place, a continuous feed of the film. The knives 7 have two cutting edges which lie in a common vertical plane and whose distance a at the knife root corresponds to the distance a between the endijoints of the incisions to be produced. The two cutting edges 12 and 1 ") converge at the top in a point lh which, when the film is touched, creates a puncture 1.ii at point 15, the center of the incision, from which the incisions are

As soon as the cutter bar has reached its highest position, the foil is driven by the drive Io for the cutter controlled stepping mechanism 19 stopped until the knife has returned to its starting position. Then the advance of the film is started again. The cutter bar can go up or down at the same time The cutting gear can be switched over as soon as the film has moved the required distance to the next row of incisions is advanced. If the cutting knife follows at the same time as the film feed is switched on again above, there is a corresponding idle stroke of the cutter bar to be provided in order to achieve the desired spacing between the rows of incisions.

The cutter bar is provided with two directional feed in the film Obergurig ge _o eneinander staggered rows of blades 0,6, which are replaces them with a gap _o, so that correspondingly staggered rows yield incision in the i'v-lie.

Angular cuts can also be seen through combination of straight but intersecting cuts, as shown in Figures 4d and e.

Such a cross cut can also be carried out with two knives according to FIG. 5 e offset from one another in the advancing direction, as is illustrated in FIG. 4 e.

The V / irlcunj; the flap 24 is shown in FIG. 7 for the different periods of growth. In the case of the flap 24a, the plant is still in the germination stage and has not yet reached the flap aurclijewschs'en.

Nimrn't drove considerably immediately after the flaps began to open and then concentrates mainly on the area of the flaps where the plants are supposed to grow.

In Figs. 8 and 9 is. the use of the cover film for drainage is shown. For drainage of the soil the Drängräben 'JJ Dränrohrs tr ength o ^ are designed from clay or plastic pipes in ■. These drainage pipes are covered by packings 29 made of filter material, for example peat or water-permeable foam. This filter pack ^ j, a cover 2 is placed according to the invention. The flaps 24 of this film are directed from the center towards the two edges 4C and 41, so that the water flowing down from above in the direction of the arrow cannot open the flaps. The water can therefore only penetrate through the fine hairline crack-like incisions that infiltrate the water, but do not allow any solid particles, e.g. fine sand, to pass, but rather hold back these solid particles so that they do not clog ^{the filter pack j> 9 and the drainage pipe.}

In a similar way to the drainage pipe string, when the cover film is used for the transport and storage of products of any kind, the film will be designed and used for covering. With such a covering of machines, for example, it is achieved that moisture

is essentially kept away, but that on the other hand condensate formed under the cover with evaporation can escape through the joints of the flap closures. .

Packaging bags for fruits, potatoes, vegetables and others Food is also provided with flap openings pointing downwards to ensure adequate ventilation to ensure and prevent visual education.

There are still many modifications within the scope of the invention and other designs possible. So can the incisions to form the flaps are also caused by knives, whose chordal shape exactly matches the desired shape of the cut is modeled and thus does not cut the cut during feed of the film, but rather when the film is at rest. If you use a knife with a knife directed against the foil Tip, so you can do without gregs that the cutting edges would quickly become blunt.
