Man hat schon vielfach vorgeschlagen und versuchtf Kunststoffolien mit farbigen Mustern zu bedrucken, um sie als Torhang- und Gardinenstoff geeignet zu machen« Die Ergebnisse waren jedoch nicht voll befriedigend« Das aufgedruckte Muster kann nicht genau die gleiche Schmiegsamkeit und Elastizität haben wie die zu bedruckende Folie«, Selbst wenn es zunächst auf der Folie festhaftet f kann es sich lokkern oder Risse erhalten und wird so bald unansehnlich. Der bedruckten Folie fehlt die so wichtige völlige Homogenität und gleichmässige Dicke9 dadurch kommt es auch, dass die als Vorhang o„dgle aufgehängte Folie nicht so gleichmässig und schön fällt9 wie in unbedrucktem homogenem Zustand»It has been suggested already widely and tried to print f plastic with colored patterns, to make them as Torhang- and curtain fabric suitable "The results were not entirely satisfactory," The printed pattern can not be exactly the same suppleness and elasticity have like to be printed film, "Even if it initially on the film adheres f may lokkern or get cracks and as soon unsightly. The printed film lacks the crucial complete homogeneity and uniform thickness 9 characterized it also comes that the curtain as o "like e suspended film is not covered as evenly and beautifully 9 as in a homogeneous state unprinted"
Überraschenderweise ist es jedoch gelungen*, all diese lachteile vollständig zu vermeiden» nämlich dadurch,, dass unter Vermeidung jeglichen Farbauftrags die Musterung dadurch hervorgerufen wird, dass die Reflektionsfähigkeit oder Lichtdurchlässigkeit der homogenen Folie dem gewünschten Muster entsprechend flächenweise verändert wirdo Surprisingly, however, it is managed *, all these laughs rush "to completely avoid namely, characterized ,, that by avoiding any color application the pattern is caused by the fact that the reflectance or transmittance to the desired pattern is changed in accordance surface as the homogeneous film o

Zu diesem Zweck können auf der einen oder auf beiden glatten Oberflächen der Folie Raster beliebiger Art ζβΒβ Kornraster oder Strichraster, letztere unter Umständen mit verschiedener Strichriehtung oder Stärke f gegebenenfalls miteinander abwechselnd angebracht oder Aufrauhungen geschaffen werden 0 For this purpose, grids of any kind ζ β Β β grain grids or line grids, the latter under certain circumstances with different lines or thicknesses f , can be alternately applied or roughening created on one or both smooth surfaces of the film 0
Das Muster kann nach einem an sich bekannten Terfahren ■durch Walzen^ deren Oberflächen durch chemische oder mechanische Behandlung entsprechend gemustert wurden^ auf die durch Vorwärmung plastisch gemachte Folie übertragen werden oder es können hierfür auch Prägewaisen des Kalanders verwendet werden^ den die Kunststoffolie bei ihrer Fertigung zuletzt durchläuftoThe pattern can be patterned according to a method known per se by rollers, the surfaces of which have been appropriately patterned by chemical or mechanical treatment Preheating plasticized film can be transferred or embossing orphans of the calender can also be used for this purpose ^ which the plastic film lasts through during its production
Für die Verwendung des neuen Verfahrens eignen sich durchsichtige oder durchscheinende Folien besonders guto For the use of the new method, transparent or translucent foils are particularly suitable or the like
