It has often proved necessary to separate land through fencing to indicate ownership, permitted areas and desired roads, and to restrict property. Special fences have been made for various purposes, from decorative fences and board fences all the way to barbed wire barriers for cattle and military purposes.

For this reason, special efforts have been made to provide a fence that would be suitable for many different purposes. This is because barbed wire fences are still used, which are washed by domestic animals because they are damaged by barbed wire. Man, on the other hand, is very careful that the fence surrounding the garden does not harm children. The fence surrounding a residential building is often made for decoration, while the fencing of domestic animals often forms a fading factor in our environment. It must be possible to move the fence around the pasture, while fixed boundary fences can be used for many other purposes. However, it is not possible to fulfill all wishes with a single fence. It has surprisingly been shown that in most cases the area can be delimited by the use of a single fence structure which takes into account the good and essential features of the existing fences. This invention relates to a movable fence that can be used without harming humans or animals.

It has proved possible to assemble a fence from one or more strips which are attached by means of plastic rings to columns made of plastic pipes. For both wild and domestic animals, it is appropriate to create fear of the fence by providing the plastic tape with an electrical conductor to which a high voltage current is applied. Thus, when an animal comes into contact with the tape, it receives an electric shock as the charge travels from the tape to the ground. Several fences of this type have been tried, resulting in several difficulties. Thanks to the wind, the tape oscillates, which is advantageous because the tape is better visible for this reason, but it also causes the tape and fasteners to be stressed, causing them to break. This stress is particularly high in the strip sections adjacent to the columns. The strength of the strip cannot be improved by widening the strip, because then it also becomes more exposed to the varying stress caused by the wind. The desired strength must therefore be obtained by increasing the thickness of the strip. Satisfactory results have only been achieved using a known three-layer tape comprising a metal strip coated with plastic on both sides. The stresses are greatest at the columns, where strong folds are created due to the fasteners used.

Not only wind but also weather affects many plastics. This is especially true for UV rays. The fence is heavily exposed to weather and wind, which is why very few plastics are in themselves strong enough.

The object of the present invention is to protect the tape against various external influences. The strip according to the invention is characterized in that said films or layers thereof are provided with yet another film or layer which is absorbing or reflecting ultraviolet radiation. For example, the tape may be protected by a colored plastic coating which is impermeable to or absorbs UV rays, and by a coating in a metal film or metal powder which reflects the radiation. These protection features can be used to expand the usability and range of the fence. Most preferably, the metal layer of aluminum reflects light and creates a glare effect that attracts attention and clearly indicates the boundary. When the second surface of the strip is provided with a colored surface that prevents the ingress of UV radiation, this forms a bright contrast to the white, brilliant snow, so that the fence is also clearly visible in winter when the ground is covered with snow. This fact is crucial when the fence is used in a game conservation context.

By coating the strip in the above-mentioned manner, a substantial advantage is obtained if the second coating is metal. When the outer conductor breaks, pulses are fed from the inner, causing small sparks to jump from the edge of the inner strip to the outer strip. When joining, a satisfactory contact is obtained when the outer metal surfaces of the strips to be joined are placed opposite each other. If the joint ruptures, there is an overflow from the inner metal layer through the outer conductor.

According to the invention, it has surprisingly been shown, by direct measurement of fatigue, that better results are obtained when the thickness of the metal film or aluminum film is reduced from 30 to 20 and further to 15. It is possible to use an aluminum film as thin as 9 pm. The lower limit is reached when a small amount of damage can cause the strip to cross due to high voltage. This can easily happen if a coating which is a powdered metal powder is used instead of a film.

The present invention will be explained with reference to the accompanying drawing, in which Figure 1 shows a fence according to the present invention, and Figure 2 shows how the strip is attached to a post of a fence according to Figure 1.

Figures 1, 2, 3 and 4 show columns, which may be plastic or any other suitable material, and which may have an arbitrary cross-section. A suitable cross-sectional shape is a circle and a suitable material is plastic, and the columns may thus preferably be tubular. Between the columns there is a planar strip 5, the core of which preferably consists of a metal strip, in which case aluminum can be used as the metal and in which case there is a plastic coating in the form of a layer or film on both sides of the metal strip. The plastic coating can be sprayed or attached in any suitable manner. According to the invention, such a strip is provided on both sides with a layer, the second layer being reflective and preferably metal and the second layer preventing the adverse effects of UV rays. The strip is twisted as shown in the figure, and at each column the strip is threaded back and forth through the ring 6, as shown in Fig. 2, so as to form a loop. The loop on the left side of the ring, as shown in Figure 2, together with the ring 6 forms a closed part which is threaded over the column and then the diameter of the loop is reduced by moving the ring to the left so that the strip is tightened around the column. The ring preferably consists of a plastic hose, in which case the wall thickness of the hose is film-like. Due to its nature, the hose can expand and compress, such as the bellows of the accordion, depending on the circumstances, thus eliminating the previous adverse effect of the fastener 6 on the strip.

Example 1:

The width of the strip is 10 mm and it consists of films glued together: 15 μm aluminum, 190 μm polyester, 15 μm aluminum, 190 μm polyester, 30 μm black polyethylene. The tape is attached to poles made of polyvinylchloride tube with fasteners of 100 μm nylon, which are connected to the tube by means of a weldable coating of polyethylene. A couple of thousand volts of electrical high-voltage pulses are conducted to the metal layers. This fence has proven to be both an electric fence and also to give the same effect as game mirrors, as it reflects both artificial and natural light.

Example 2:

In order to reduce the effect of wind without reinforcing the plastic, an 8 mm wide strip comprising an inner
