DUsengerät für die Überlapp—Schweißung thermoplastischer Kunststoff-Folien mittels Warmgas u. Heizkeil DUsengerät for the Ov-rlapp Schw e ißung thermoplastic plastic film by means of W ARMG as u. Wedge
Beschreibung; Description ;
Es sind keilförmige Folien-Schweiß-I'üsen bekannt, die mit Warmgas beschickt werden, an deren Schneide das '-.Varmgas austritt und zwischen die zu verschweißenden Folien-Lappen strömt. Außer durch Warmgas wird die Plastifizierung der zu verschweißenden Lappen durch Berührung mit der Ober- und Unterseite der flachen "Düse gefördert. Die sich gegenüberliegenden flächen der Lappen werder, plastifiziert und anschließend wird durch eine Rolle von oben der nötige Schweißdruck ausgeübt.There are wedge-shaped film welding nozzles known with Hot gas are charged, at the edge of which the '-.Varmgas emerges and flows between the foil flaps to be welded. In addition to hot gas, the plasticization of the too Welding rag promoted by touching the top and bottom of the flat "nozzle. The opposite surfaces of the flaps are plasticized and then the necessary welding pressure is exerted from above by a roller.
"Dies Verfahren ist nur anwendbar, wenn die Lappen der zu verschweißenden FoJ ■> enbahnen auf einer ebenen Unterlage liegen. Tst die Unterlage nicht eben, so müssen Bretter, Leisten, Holzfaserplatten oder starke Pappe untergelegt werden, die nach der Verschwenkung besonders bei langen Nähten schwer zu entfernen sind."This procedure is only applicable when the lobes are too welding foJ ■> the tracks lie on a level surface. If the base is not level, boards, strips, fibreboard must be used or strong cardboard is placed underneath, which is difficult to remove after pivoting, especially with long seams are.
Sollen Übe rlapp-Verschwei !Jungen der -'olienränder an Böschungen z.B. bei ,",eichabdichtungen ur/.v. vorgeno-men werden, so ist dies Verfahren bei ä.em rauhen Untergrund nur bedingt anwendbar. Das Prinzip der Erfindung liegt in der Verwendung zweier Rollen, die durch Pederdruck die schweißbarer. Folien—Lappen zusammendrücken und deren Achsen versetzt und einseitig in. Auslegerarmen befestigt sind. Die untere Solle wird von einer Seite unter den unteren FoIien—Lapper geschoben, der mit seiner Oberseite die ünterflache der Keildüse streift. Der Lappen der oberen Folie wird von der anderen Ceite unter die obere Rolle eingeführt und streift mit seiner Unterseite die Oberfläche der Keildüse. Die .''arrr.luft strömt aus der Düse zwischen die von den Rollen zusammengedrückten Folienränder, wo dann die VerschweiSung unter dem Anpreßdruck der Rollen erfolgt.If overlap welding is to be carried out on the edges of the foil on embankments, for example at, ", calibration seals ur / .v., This method can only be used to a limited extent on a rough subsurface. The principle of the invention lies in the Use of two rollers, which press the weldable foil tabs together by pedal pressure and whose axes are offset and attached to one side in cantilever arms. The lower part is pushed from one side under the lower foil lapper, the upper side of which brushes the surface of the wedge nozzle The flap of the upper film is inserted from the other side under the upper roll and its underside brushes the surface of the wedge nozzle. The air flows out of the nozzle between the edges of the film, which are pressed together by the rolls, where the weld is then underneath the contact pressure of the rollers takes place.

worden kann_. can be _.
Die Erfindung hat für die Baufolien-Verlegung praktische und wirtschaftliche Bedeutung insofern, als Folienbahnen mit Pabrikationsbreiten ohne Vorfabrikation auf der Baustelle verschleißt werden können.The invention is useful for laying construction film and economic importance insofar as film webs with production widths without prefabrication on the construction site can be worn out.
Das Düsengerät selbst ist so gestaltet, daß die Rollen vor Beginn einer Schweißung auf einen festen Abstand eingestellt werden können. Die Folien-Ränder können von der einen und auch von der anderen Seite eingeführt werden. In die Warmgasleitung, die zur Keildüse führt, ist ein Drei-= wege-ventii eingebaut, aus dem das Warrngas bis zum Beginn der Schweißung vom Material abgelenkt wird und seitlich austritt. Die Keildüse ist also kalt, Warmluft strömt nicht aus und das Ansetzen oder Einfädeln des Rollenpaares kann bewirkt werden, ohne daß ein Fehlstart zu befürchten ist. Erst wenn die Überlappung geordnet ist, wird die obere Rolle von Hand auf Federdruck gestellt und das Dreiwege-Ventil von Hand geöffnet. Nach einigen Sekunden wird die Düse in Naht-Längsrichtung von Hand gezogen und die Überlapp-Schweißung ausgeführt.The nozzle device itself is designed so that the rollers are set at a fixed distance before starting a weld can be. The edges of the film can be inserted from one side or the other. There is a three = in the hot gas line that leads to the wedge nozzle wege-ventii installed, from which the warning gas until the beginning the weld is deflected by the material and laterally exit. The wedge nozzle is therefore cold, warm air does not flow out and the attachment or threading of the roller pair can without fear of a false start. Only when the overlap is in order will the upper one The roller is set to spring pressure by hand and the three-way valve is opened by hand. After a few seconds, the The nozzle is drawn by hand in the longitudinal direction of the seam and the overlap weld is carried out.
Zum Betrieb des Düsengerätes sind Warmgas-Schweißgeräte bekannter Art notwendig, an die das Düsengerät angeschraubt wird.To operate the nozzle device, hot gas welding devices of a known type are required, to which the nozzle device is screwed.
Das Düsengerät wird im Einzelnen an Hand der Zeichnungen folgendermaßen beschrieben:The nozzle device is described in detail using the drawings as follows:
Bild 1 aeigt die Seitenansicht. Am Körper 1 wird das Warmgas-Schweißgerät 2 angeschraubt. Das Rohr 3 führt zur KeildüseFig. 1 shows the side view. The hot gas welding device is attached to the body 1 2 screwed on. The pipe 3 leads to the wedge nozzle
Mit dem Körper 1 sind die Auslegeramie 5 u. 6 fest verbunden. "Der Auslegerarm 7 ist nach oben und unten verstellbar. Durch Hochziehen und Drehen des Stiftes 8 wird der Abstand der Rollen 3 und IO ei'^Hstellt. T)ie Druckfeder 11 erzeugt nach entrasten des Stiftes 8 den Schweißdruck. Mit dem j-7/egeVentil 12 kann der Warmluftstrom so gelenkt werden, daß er entweder seitlich frei austritt, ohne Material und Schweißer zu gefährden, oder zur Keildüse geführt wird. Der untere Folienrand 13 wird zwischen die Keildüse 4 und der Oberseite der unteren Rolle 10 und der obere Polienrand 14 zwischen die Keildüse 4 und der Unterseite der obereren Rolle 9 geführt.The extension armament 5 and 6 are firmly connected to the body 1. The extension arm 7 can be adjusted upwards and downwards. By pulling up and turning the pin 8, the distance between the rollers 3 and IO is adjusted. The compression spring 11 generates the welding pressure after the pin 8 is unlocked / egeVentil 12, the hot air flow can be directed so that it either exits freely laterally without endangering material and welders, or is guided to the wedge nozzle. The lower film edge 13 is between the wedge nozzle 4 and the top of the lower roller 10 and the upper polishing edge 14 guided between the wedge nozzle 4 and the underside of the upper roller 9.
