Transparent laminates with heating wires are known. In this case, the heating wire is provided in the synthetic resin layer between the lower plate and the upper plate. The lower and upper plates are usually glass plates with an intermediate layer of synthetic resin. Instead of glass plates, other materials such as polymethyl-methacrylate-synthetic resin (PMMA) can be used. PMMA is a hard synthetic resin. Vinyl-butyl-aldehyde-resin is recommended as the material for the intermediate layer. The heating wire and the strip conductor are embedded in this resin. British Patent No. 97245

A solution is provided at the edges, in which the strip conductors are coated on the lower and upper plate sides with a coating film, which coating film consists of a synthetic resin which does not react with the material of the strip conductors.

板の製作は一つの方法ステップで可能である。When making a transparent plate, the lower cover film, the correspondingly cut heating conductors and the upper cover film are placed on the lower plate, and after the upper plate is attached the heating and cooling process. Can be pasted together. At that time, the heating conductors are simultaneously fixed, and the two synthetic resin plates are connected so that they are permanently transparent and do not form a scratch. The production of the transparent plate is possible in one method step.

取りが達成される。The reaction between the material of the plate and the material of the strip conductor is prevented by the insertion of the covering film. If the covering film is dyed, for example, in black, and extends over the entire edge area of the transparent plate, edging of the transparent plate is achieved, as is usual in glass sheets today.

It has almost the same mechanical properties as.

取付けの前に対応する幅に切断することができる。If the heating conductor is formed as a fabric,
Its rational production is possible. Highly conductive wires extending in the warp direction are woven as strip conductors on both longitudinal edges of the fabric. In particular, the strip conductor extends substantially horizontally when the transparent plate is installed. Thereby, the heating conductor can be produced as a rollable textile strip of any length and cut to the corresponding width before mounting the transparent plate.

特にアクリル酸塩フィルムによって被覆されている。The high electrical conductivity of the strip conductors on the longitudinal edges of the heating conductors is achieved when the wire consists of copper. In particular, the diameter of the strip conductor wire is larger than the diameter of the heating wire. When the woven fabric including the strip conductor is thinned by rolling, it is advantageous because the strip conductor does not project. In order to prevent the reaction between copper and polyvinyl chloride that occurs over time,
The strip conductors are coated on the upper and lower flexible PVC plates, in particular with an acrylate film.

Especially when it consists of chromium-nickel wire with a diameter of less than 0.05 mm, the complete connection of the upper plate is made in the mesh when the upper plate is applied to the lower plate. Thereby very good transparency is obtained.

This is, for example, using lines with different thicknesses, using lines with different material compositions, arranging lines with different intervals in the warp direction and the weft direction, woven fabrics with different shapes from the right-angle mesh shape, Alternatively, it is achieved by making the woven fabric non-conductive in the warp direction, in particular by using non-conductive lines or fibers extending in the warp direction.

It is recommended to adjust the resistance of. The resistance of the heating conductors is interrupted in the region of the transparent surface of the heating conductors so as to at least electrically insulate transversely to the strip conductors by at least 1 degree, and one of the strip conductors also at least 1 degree. At least interrupted to provide electrical insulation, thereby forming at least two heating zones,
It is possible to increase. Thereby, the heating conductors are divided into resistance groups forming two or more heating ranges, which resistance groups are conductively connected to one another via strip conductors which pass through the edge sections.

With an even number of heating conductors formed, it is possible to mount the electrical connections of the strip conductors respectively near the lower outer edge of the transparent plate.
