Description

Vorrichtung zur kontinuierlichen Herstellung und Behandlung von vorzugsweise flächigen Werkstoffen Zusatz zum Patent S53402 Die Erfindung bezieht sich auf eine weitere Ausgestaltung und Verbesserung der durch Patent 853 402 geschützten Vorrichtung zur kontinuierlitzen Herstellung oder Behandlung von vornehmlich flächigen Werkstoffen in Form von Platten, Folien, Bändern, Streifen, Leisten sowie von Werkstücken mit einfachen flächigen Begrenzungsformen aus natürlichen oder synthetischen plastischen Massen mit oder ohne faserigen, schnitzelförmigen oder pulverförmigen Füllstoffen organischer oder anorganischer Herkunft, sowie aus hydratisierter Cellulose durch Verdichtung gegebenenfalls mit gleichzeitiger oder anschließender Verformung, sowie auf die kontinuierliche Behandlung dieserW\terkstoffe zum Zwecke der Oberflächenveredlung durch Polieren, Mattieren, Prägen, Glätten, Kaschieren und Verschweißen mittels heiz- und/oder kühlbarer Preßwerkzeuge, zwischen denen der zu bearbeitende Werkstoff unter Zuhilfenahme endloser Transportbänder hindurchgeführt und kurzzeitigen, pulsierenden Druck- oder Stoßimpulsen ausgesetzt wird. Die Druck oder Stoßimpulse werden hierbei durch eine Flüssigkeit übertragen, die in einem durch eine Membran abgesperrten Hohlraum eingeschlossen ist, der mit einem z. B. aus Zylinder und Kolben bestehenden, kurzzeitige Druckimpulse erzeugenden Antriebsorgan in Verbindunng steht, wobei der zu verarbeitende Werkstoff zwischen der Membran und den heiz- und kühlbaren Druckwerkzeugen hindurchgeführt wird.Device for the continuous production and treatment of preferably flat materials addendum to patent S53402 The invention relates to a further development and improvement of the device protected by patent 853,402 for the continuous production or treatment of mainly flat materials in the form of sheets, foils, tapes, strips, strips and workpieces with simple two-dimensional boundary forms made of natural or synthetic plastic Masses with or without fibrous, shredded or powdered fillers of organic or inorganic origin, as well as from hydrated cellulose Compression, if necessary with simultaneous or subsequent deformation, as well as on the continuous treatment of these materials for the purpose of surface finishing by polishing, matting, embossing, smoothing, lamination and welding by means of heatable and / or coolable pressing tools, between which the material to be processed passed through with the help of endless conveyor belts and short-term, pulsating Is exposed to pressure or shock pulses. The pressure or shock pulses are here transferred through a liquid that is shut off in a membrane by a membrane Cavity is included, which with a z. B. consisting of cylinder and piston, short-term pressure pulses generating drive member is in connection, the Material to be processed between the membrane and the heatable and coolable pressure tools is passed through.

Bei Arbeiten mit sehr hohen Drücken, wie sie z. B. zur Herstellung von Hartpapier notwendig sind, werden aber die dünnen Membranen mechanisch sehr stark beansprucht. Gemäß der Erfindung wird daher vorgeschlagen, den unter pulsierenden Druckeinwirkungen stehenden Flüssigkeitsbehälter durch einen oder mehrere vorzugsweise platten-oder pilzförmige mit der Bodenfläche unmittelbar auf den zu behandelnden Werkstoff einwirkende Kolben abzuschließen. Die Kolben können bei dieser Anordnung sowohl auf einer Seite allein als auch beiderseits der zu behandelnden Werkzeugbahn angeordnet sein. When working with very high pressures, such as. B. for production of hard paper necessary are, but become the thin membranes mechanically very heavily stressed. According to the invention it is therefore proposed the liquid container, which is under pulsating pressure effects, through a or several preferably plate-shaped or mushroom-shaped directly with the bottom surface complete piston acting on the material to be treated. The pistons can with this arrangement both on one side alone and on both sides of the one to be treated Tool path be arranged.

Bei der Verarbeitung sehr dünner Platten oder Folien, vorzugsweise unter 0,5 mm, aus Hartpapier o. dgl. ist jedoch ein Ausgleich der Ungleichmäßigkeiten in der Druckübertragung erforderlich, weshalb zur weiteren Verbesserung der Vorrichtung gemäß der Erfindung auf der einen Druckseite ein oder mehrere unter pulsierendem Flüssigkeitsdruck stehende Kolben und auf der anderen Druckseite eine oder mehrere unter pulsierendem Flüssigkeitsdruck stehende Membranen angeordnet sind. Anstatt dessen kann aber vorteilhaft auch der Boden der Kolben selbst als Membran ausgebildet sein. Beiderseits der Werkstoffbahn sind zweckmäßig noch Druck- und Kühlplatten vorgesehen, zwischen denen der Werkstoff hindurchgeführt wird. Die Druckimpulse werden dann über diese Heiz- oder Kühlplatten mittels der Kolben auf den Werkstoff übertragen. When processing very thin sheets or foils, preferably Less than 0.5 mm, made of hard paper or the like, however, compensates for the irregularities required in the pressure transmission, which is why to further improve the device according to the invention on the one pressure side one or more under pulsating Pistons at liquid pressure and one or more pistons on the other pressure side under pulsating liquid pressure are arranged membranes. Instead of however, the bottom of the piston itself can also advantageously be designed as a membrane be. Pressure and cooling plates are also expediently placed on both sides of the material web provided, between which the material is passed. The pressure pulses are then applied to the material via these heating or cooling plates by means of the pistons transfer.

The lower part 2 resting on the foundation frame I is a cylinder body formed, in which the full-walled piston 4, which is provided with a seal 3 set in oscillating movements under the pulsating pressure of the liquid 5 will.

Über dem schwingenden Kolben sind die Heizplatten 6 und die KZihlplatten 7 unter Zwischenlage einer Isolierlages angeordnet. Der Oberteilg der Vorrichtung ist gleichfalls mit Heizplatten Io und Kühlplatten 11 versehen. Zwischen diesen Heiz- und Kühlplatten wird der Werkstoff I2 mittels der über Walzen 13 angetriebenen Transportbänder 14 hindurchgeführt. Bei der Ausführungsform nach Abb. 2 sind nur im Oberteil 15 Heizplatten I6 und Kühlplatten 17 vorgesehen, während die als Membran ausgebildete Bodenfläche IS des schwingenden Kolbens Ig unmittelbar an dem zu behandelnden Werkstoff 20 anliegt. Dieser Kolben 19 ist in dem zylindrischen Unterteil 21 geführt und steht unter dem Druck der pulsierenden Flüssigkeit 22, gegen deren Austritt an dem Kolben die Dichtungen 23 angebracht sind. Der Werkstoff 20 wird mittels der über Rollen 24 angetriebenen Transporthänder 25 zwischen den Heiz- und Kühlplatten einerseits und dem Kolben mit der als Membran ausgebildeten Bodenfläche andererseits hindurchgeführt.The heating plates 6 and the cooling plates are located above the oscillating piston 7 arranged with the interposition of an insulating layer. The top part of the device is also provided with heating plates Io and cooling plates 11. Between these The material I2 is driven by means of rollers 13 for heating and cooling plates Conveyor belts 14 passed through. In the embodiment of Fig. 2 are only in the upper part 15 heating plates I6 and cooling plates 17 are provided, while the membrane formed bottom surface IS of the oscillating piston Ig directly on the to be treated Material 20 is applied.
