Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Bändern und Folien durch Warmgelieren und nachfolgendes Auswalzen thermoplastischer Kunststoffe. The invention relates to a device for producing tapes and foils by hot gelling and subsequent rolling out of thermoplastic plastics.

Die bekannten Vorrichtungen der zum vorerwähnten Zweck und für eine Verbesserung gemaß der Erfindung in Betracht kommenden Art bestehen aus Misch- und Bandwalzwerken (Kalander). Die Mischwalzwerke dienen speziell dem Zwecke des Warmgelierens und Mischens der Kunststoffmasse, die z. B. als eine mit irgendeinem zweckentsprechenden Weichmachungsmittel untermischte Polyvinylchloridmasse gegeben sein mag. The known devices of the aforementioned purpose and for a Improvement according to the invention under consideration consist of mixing and Strip rolling mills (calenders). The mixing mills are used specifically for the purpose of hot gelling and mixing the plastic mass, e.g. B. as one with any appropriate purpose Plasticizer mixed in with polyvinyl chloride mass may be given.

Es bedarf allerdings einer gewissen Zeit, bevor die zur Genüge gelierte Masse von den Arbeitswalzen abgenommen, fellartig heruntergeschnitten und stückweise, zusammengerollt zu sog. Puppen, auf das Bandwalzwerk (Kalander) übertragen werden kann. Da letzteres dauernd und zudem auch möglichst gleichmäßig beschickt werden muß, ein einziges Mischwalzwerk diesem Zwecke jedoch nicht zu dienen vermag, waren stets mehrere Mischwalzwerke erforderlich; es gab dadurch hohe AI1-schaffungskosten und auch unerwünscht hohe Betriebskosten. Hinzu kam der Nachteil, daß bei der Vielzahl der zur Bedienung der Mischwalzweil<e erforderlichen menschlichen Arbeitskräfte der Persönlichkeitsfaktor eine wesentliche Rolle mitspielte.However, it takes a certain amount of time before it gelled sufficiently Mass removed from the work rolls, cut down like fur and piece by piece, rolled up into so-called dolls, transferred to the strip rolling mill (calender) can. Since the latter are fed continuously and also as evenly as possible must, but a single rolling mill cannot serve this purpose several mixing mills always required; This resulted in high AI1 creation costs and also undesirably high operating costs. There was also the disadvantage that with the large number the human labor required to operate the mixed whale parts the personality factor played an essential role.

Jedenfalls war die Gewähr der Gleichmäßigkeit des vom Bandwalzwerk gelieferten Endproduktes keine genügend vollkommene, weil auf den Mischwalzwerken gelierte Masse nur stückweise, in Form sog. Puppen auf das Endwalzwerk zu übertragen war. Gewisse Unterschiede in der Beschaffenheit der Puppen ließen ein und dasselbe Enderzeugnis in seiner Qualität und im Aussehen stellenweise oft sehr unterschiedlich ausfallen.In any case, the uniformity of the strip mill was guaranteed The final product delivered is not sufficiently perfect because it is on the mixing mills gelled mass to be transferred to the final rolling mill only in pieces, in the form of so-called puppets was. Certain differences in the nature of the dolls allowed one and the same thing End product often very different in its quality and appearance fail.

Der Zweck der Erfindung ist, Vorrichtungen der eingangs erwähnten Art im Sinne der Beseitigung all der vorerwähnten Mängel und Nachteile zu verbessern, d. h. eine Vorrichtung zu schaffen, die konstruktiv einfacher und billiger, außerdem auch leistungsfähiger und wirtschaftlicher als die bisherige ist. The purpose of the invention is to provide devices of the type mentioned in the opening paragraph To improve kind in the sense of eliminating all the aforementioned shortcomings and disadvantages, d. H. to create a device that is structurally simpler and cheaper, as well is also more efficient and economical than the previous one.

Die Erfindung bringt nun eine in ihrer Art grundsätzlich neue Vorrichtung, mittels welcher die Kunststoffbänder und Folien wohl immer noch in an sich bekannter Weise durch Warmgelieren und nachfolgendes Auswalzen thermoplastischer Masse hergestellt werden, und zwar besteht die Erfindung darin, daß ein strahlungsbeheizter Bandtunnelofen die darin gelierte Kunststoffmasse einem Kalander stetig und bandförmig, gegebenenfalls in voller Walzenbreite, zuführt. The invention now brings a device that is fundamentally new in its type, by means of which the plastic tapes and foils are probably still known per se Way produced by hot gelling and subsequent rolling out of thermoplastic mass the invention consists in that a radiation-heated belt tunnel furnace the plastic compound gelled therein is continuously and band-shaped, possibly in a calender in full roller width, feeds.

Die Zeichnung veranschaulicht eine schematische Darstellung einer erfindungsgemäßen Vorrichtung. The drawing illustrates a schematic representation of a device according to the invention.

0 bezeichnet den an sich bekannten Bandtunnelofen zum Warmgelieren der Kunststoffmasse und I das Walzwerk bzw. den Kalander zum bandförmigen Auswalzen der im Bandtunnelofen 0 gelierten Masse. Das Förderband I ist endlos und stetig umlaufend. Die an der bei 2 angedeuteten Stelle schichtartig aufgebrachte Masse wird vom Förderband I durch den wärmestrahlenden Tunnel 3 hindurchgeführt und hinter dem Auslauf des Tunnels als geliertes Masseband ausgetragen. Vom Förderband I geht das gelierte Masseband in den Kalander K über. 0 denotes the well-known belt tunnel furnace for hot gelation the plastic compound and I the rolling mill or the calender for strip-shaped rolling the mass gelled in the belt tunnel oven 0. The conveyor belt I is endless and continuous circulating. The mass applied in layers at the point indicated at 2 is passed from the conveyor belt I through the heat radiating tunnel 3 and behind discharged from the outlet of the tunnel as a gelled ground tape. From conveyor belt I goes the gelled ground tape into the calender K over.

Die Gleichmäßigkeit der dem Band aufgetragenen Masseschicht ist durch eine an sich bekannte Aufstreichvorrichtung 4 einwandfrei erzielbar. The uniformity of the mass layer applied to the tape is through a spreading device 4 known per se can be achieved without any problems.

Ebenso gleichmäßig ist die zur Massegelierung notwendige Wärmebehandlung im Wärmestrahlungstunnel 3 verbürgt.The heat treatment required for mass gelation is just as uniform guaranteed in the thermal radiation tunnel 3.

Der Bandtunnelofen 0 ersetzt die bisherigen Mischwalzwerke, ist konstruktiv einfacher, auch wesentlich billiger und nicht nur Mittel zum an sich bekannten Zwecke des Gelierens, sondern zugleich auch Mittel zum Zwecke des kontinuierlichen Einspeisens bandförmig gelierter Masse in das Endwalzwerk bzw. den Kalander. The belt tunnel furnace 0 replaces the previous mixing and rolling mills, is constructive simpler, also much cheaper and not just a means for known purposes of gelling, but at the same time also means for the purpose of continuous feeding band-shaped gelled mass in the final rolling mill or the calender.
