Description
459 024 När det gäller persiennsegment av aluminiumplåt, tillverkas dessa i form av långa band, exempelvis på 500 m, som transporteras på rullar och vid beställning av en persienn med ett specialmått kapas, stansas och formas persiennsegmentet av det färdigpreparerade plåtban- det. Detta är ett mycket fördelaktigt förfarande, som man även försöker tillämpa på den avsevärt mycket billigare plastpersiennen. Vid dessa försök har man emellertid stött på problem, eftersom plasten är mycket svårare att forma vid kallbearbetning än aluminiumplåten. Av kostnads- skäl kan vid sådan framställning av persiennsegment endast användas en kontinuerligt löpande framställning, vilket omöjliggör varmbearbetning av varje separat segment, för att det skall erhålla den önskade tvär- snittsformen. 459 024 In the case of blind segments of aluminum sheet, these are manufactured in the form of long strips, for example of 500 m, which are transported on rolls and when ordering a blind with a special dimension, the blind segment is cut, punched and shaped by the ready-made sheet. This is a very advantageous method, which is also tried to be applied to the considerably cheaper plastic blind. In these experiments, however, problems have been encountered, since the plastic is much more difficult to shape in cold working than the aluminum sheet. For cost reasons, only such a continuous production can be used in such production of blind segments, which makes it impossible to hot-work each separate segment, in order for it to obtain the desired cross-sectional shape.
Det har även gjorts försök med att extrudera plasten med den slutliga tvärsnittsformen och rulla det extruderade bandet på rullar, men vid detta förfarande blir de färdiga persiennsegmenten ej raka.Attempts have also been made to extrude the plastic with the final cross-sectional shape and roll the extruded strip on rolls, but in this process the finished blind segments do not become straight.
Eftersom persiennsegmentens rakhet är absolut nödvändig för persiennens funktion, är detta tillverkningssystem omöjligt att använda i prakti- ken. Ändamålet med föreliggande uppfinning är att åstadkomma ett plastband, som möjliggör, att persiennsegment kan tillverkas i långa längder, som kan rullas på rullar och därefter kapas och medelst kall- bearbetning ges sin slutliga form, samt ett förfarande för framställning av dessa plastband.Since the straightness of the blind segments is absolutely necessary for the function of the blind, this manufacturing system is impossible to use in practice. The object of the present invention is to provide a plastic strip which enables blind segments to be manufactured in long lengths, which can be rolled on rolls and then cut and given their final shape by cold working, and a method for producing these plastic strips.
Denna uppgift har lösts genom att bandet, där det efter slutgil- tig bearbetning kommer att uppvisa en vinkling, på insidan av denna vinkling är försett med längsgående spår.This task has been solved by providing the belt, where it will finally have an angle after final processing, with longitudinal grooves on the inside of this angle.
Vid ett fördelaktigt utförande av tillverkningsförfarandet framställes spåren vid extruderingen, uppvisar motsvarande upphöjningar.In an advantageous embodiment of the manufacturing process, the grooves are produced during the extrusion, exhibiting corresponding elevations.
I det följande skall ett fördelaktigt utföringsexempel på upp- finningen beskrivas med hänvisning till de bifogade ritningarna. Fig. 1 är en perspektivvy av en persienn och fig. 2 - 7 visar exempel på plac ring av spåren enligt uppfinningen vid olika tvärsnitt menten. genom att extruderingsverktyget e- på persienn- seg- 459 024 En persienn 1 består huvudsakligen av ett antal persiennsegment 2, vilka är förbundna med varandra via ett antal manövreringssnören 3, såsom framgår av fig. 1.In the following, an advantageous embodiment of the invention will be described with reference to the accompanying drawings. Fig. 1 is a perspective view of a blind and Figs. 2 - 7 show examples of placement of the grooves according to the invention at different cross-sectional elements. in that the extrusion tool e- on blinds 459 024 A blind 1 consists mainly of a number of blind segments 2, which are connected to each other via a number of operating cords 3, as shown in Fig. 1.
Av fig. 2 framgår det, hur spåren 4 skall placeras, om man önskar den tvärsnittsform på persiennsegmentet som visas i fig. 3. På samma sätt visas i fig. 4 resp. 6 hur spåren 4 skall placeras, om man önskar de tvärsnittsformer som visas i fig. 5 resp. 7.Fig. 2 shows how the grooves 4 are to be placed, if the cross-sectional shape of the blind segment shown in Fig. 3 is desired. In the same way, Figs. 6 how the grooves 4 are to be placed, if the cross-sectional shapes shown in fig. 5 resp. 7.
Genom att på insidan av den böjning som åstadkommas vid kallbearbetningen, anbringa spår 4 enligt uppfinningen reducerats de naturliga spänningarna i plastbandet efter bearbetningen, som strävar efter att få bandet att återta sin ursprungliga form, så mycket att risken för att persiennsegmenten 2 skall återgå till den platta form som det uppvisar före bearbetningen har helt eliminerats.By applying grooves 4 according to the invention to the inside of the bend produced during the cold processing, the natural stresses in the plastic strip after the processing, which strive to get the strip to regain its original shape, are reduced so much that the risk of the blind segments 2 returning to the flat shape that it exhibits before processing has been completely eliminated.
Det bör även framhållas, att uppfinningen ej är begränsad till de ovan beskrivna utföringsexemplen, utan flera olika utföranden är möjliga inom ramen för de efterföljande patentkraven. Persiennsegmenten kan exempelvis ha en helt annan tvärsnittsform än någon av de som visas i fig. 3, 5 resp. 7.It should also be emphasized that the invention is not limited to the embodiments described above, but several different embodiments are possible within the scope of the following claims. The blind segments may, for example, have a completely different cross-sectional shape than any of those shown in Figs. 7.
