Description

Die Erfindung betrifft ein Verfahren zur kontinuierlichen Herstellung von endlosen, optisch abbildungsfähigen Folien, insbesondere Bahnen und Platten aus Kunststoffen.The The invention relates to a process for continuous production of endless, optically imageable films, in particular Webs and sheets of plastics.

In der deutschen Patentschrift DE 199 43 604 C2 ist ein Verfahren beschrieben welches ebenfalls die kontinuierliche Herstellung von endlosen, optisch abbildungsfähigen Folien, Bahnen und Platten aus Kunststoffen zum Inhalt hat wie auch die der Entgegenhaltungen in bezeichneter Patentschrift. Das angezogene, patentierte Verfahren setzt die Verwendung einer Gravurwalze voraus, die während einer Umderhung in einem definierten Durchgangsbereich auf die Temperatur der Kunststoffschmelze zu bringen und in einem weiteren, definierten Bereich auf Erstarrungstemperatur derselben abzusenken ist.In the German patent DE 199 43 604 C2 is a method described which also has the continuous production of endless, optically imageable films, sheets and plates made of plastics content as well as that of the references in said patent specification. The tightened, patented method requires the use of a gravure roll, which is to bring during a change in a defined passage area to the temperature of the plastic melt and lower in a further defined range to its solidification temperature.

Bei Bahnen und Platten mit Wandstärken über 1 mm sind thermische und rheologische Probeme zu bewältigen, die sich nur auf Kosten der Produktionswirtschaftlichkeit und Qualität der Produkte bedingt lösen lassen. Beispielsweise muß nach den bekannten Verfahren das wandstärkere Produkt vor der völligen Aushärtung im weichplastischen Zustand von der Gravurwalze abgenommen werden um es in der Planlage aushärten zu lassen. Dabei kommt es bei dem übergang des erstarrenden Schmelzenbandes aus der Rundung der Gravurwalze in die Planlage zur Stauchung der glatten Produktoberfläche und zur Streckung der strukturierten Fläche. Beim Ausgleich der Längendifferenz beider Flächen machen sich bei manchen Materialtypen der Schmelze Transmissionsbeeinträchtigungen bemerkbar. Je stärker das Schmelzenband bzw. das Endprodukt je größer ist die Differenz zwischen Stauchung und Streckung der sich gegenüberliegenden Oberflächen. Zudem ist die Abnahme des notwendigerweise noch weichplastischen Materials aus der formenden Gravur problematisch, da beim übergang der Kunststoffschmelze aus dem weichplastischen in den hartelastischen Zustand eine unkontrolierte Volumenkontraktion (Schwindung) zu eliminieren ist, die durch eine qualitätsmindernde Rundung spitzwinkeliger Strukturen in Erscheinung tritt.at Webs and panels with wall thicknesses greater than 1 mm There are thermal and rheological problems to deal with, which are only at the expense conditional on the production economy and quality of the products. For example, after the known method, the wall thicker product before complete curing in soft plastic state can be removed from the gravure roll around cure it in the flatness allow. It comes at the transition of the solidifying melt ribbon from the rounding of the gravure roll in the flat position for compression of the smooth product surface and for stretching the structured surface. When compensating the difference in length both surfaces With some types of material of the melt, transmission impairments occur noticeable. The stronger that Melt ribbon or the end product the larger the difference between Compression and extension of the opposite surfaces. moreover is the decrease of the necessarily soft plastic material from the forming engraving problematic, since the transition of the plastic melt the soft plastic in the hard elastic state an uncontrolled Volume contraction (shrinkage) is eliminated by a quality-reducing Rounding acute-angled structures appears.

Mit der Erfindung bedingt vergleichbare Verfahren zur Herstellung scharfkantig strukturierter Flächenprodukte aus Plaste sind u.a. in den Patentschriften JP 111 29 273 A und DE 198 45 652 A1 beschrieben, in denen jedoch nicht beschrieben ist wie die, bei der Erstarrung des Plastbandes (Schmelze) eintretende Materialkontraktion so eliminiert wird, daß eine Beeinträchtigung der optischen Wirkung des strukturierten Plastbandes absolut ausgeschlossen wird, die sich dadurch kennzeichnet, daß sich die scharfen Ausfomungen der abzubildenden Gravuren, beispielsweise prismatische Strukturen durch ungenügenden Nachdruck auf die erkaltende, kontraktierende Materialschmelze nicht ausreichend füllen. Demzufolge lag der Erfindung die Aufgabe zu Grunde die Vorrichtung zur Ausübung des Verfahrens zu befähigen, die Materialschwindung durch Anwendung hohen Druckes auf die erkaltende, kontraktierende Schmelze zu eliminieren. Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruches 1 gelöst.With the invention conditionally comparable methods for producing sharp-edged structured surface products of plastic are, inter alia, in the patents JP 111 29 273 A and DE 198 45 652 A1 described in which, however, is not described as the, in the solidification of the plastic band (melt) entering material contraction is eliminated so that an impairment of the optical effect of the structured plastic band is absolutely excluded, which is characterized in that the sharp Ausfomungen of the imaged Engraving, for example prismatic structures, can not be sufficiently filled by insufficient emphasis on the cooling, contracting molten material. Accordingly, it was an object of the invention to enable the apparatus for practicing the method to eliminate material shrinkage by applying high pressure to the decaying, contracting melt. This object is achieved by a method having the features of claim 1.
