Description

Gegenstand vorliegender Erfindung ist ein Verfahren, das geeignet ist, Gegenstände aus zwei übereinanderliegenden Folien aus Polyäthylen oder ähnlichen Stoffen mittels elektrisch erhitzter Leiter an den Rändern aneinanderzuschweißen und gleichzeitig auszuschneiden. The present invention is a method which is suitable is, objects made of two superimposed sheets of polyethylene or similar Welding fabrics together at the edges by means of electrically heated conductors and cut out at the same time.

In der Abb. I stellen a und a1 Vorratsrollen dar, auf welchen die Folien in Bandform b aufgewickelt sind und durch die Transportrollen c und c1 abgewickelt werden. Der Weg der Bänder führt über eine Walze D, welche in beliebig viele Flächen d, dt, d2 unterteilt ist. Jede dieser Flächen trägt einen elektrischen Heizleiter e, e1 (Draht), der in seiner Form die Umrisse eines Körpers aufweist (Abb. 2). In Fig. I, a and a1 represent supply rolls on which the Films are wound in tape form b and unwound by the transport rollers c and c1 will. The path of the belts leads over a roller D, which can be used in any number of surfaces d, dt, d2 is divided. Each of these surfaces has an electrical heating conductor e, e1 (wire), which has the shape of a body (Fig. 2).

Über der Walze D befindet sich ein ab und auf zu bewegender Stempel f, der beim Niedergang die Folien auf den inzwischen stromdurchflossenen Leiter e drückt, wodurch das Schweißen und Ausschneiden bewirkt wird. Durch das Abheben des Stempels wird der Strom abgeschaltet und dem Leiter und den Schweißstellen ein Luftstrom durch Düsen unterhalb des Bandes in der Walze befindlich, zur Abkühlung zugeführt. Gleichzeitig dreht sich die Walze so weit in der Pfeilrichtung, daß die nächste Fläche dem Stempel gegenübersteht. Das ausgeschnittene Teil wird dann durch einen stärkeren Luftstrom durch das geeignete Gebläse emporgehoben, und der Streifen kann weitertransportiert werden. Above the roller D there is a stamp to be moved from time to time f, who at the companionway the foils on the now current-carrying conductor e presses, thereby causing welding and cutting out. By taking off the punch, the current is switched off and the conductor and the welds on Air flow through nozzles located below the belt in the roller, for cooling fed. At the same time, the roller rotates so far in the direction of the arrow that the next surface is opposite the stamp. The cut out part will then go through a stronger airflow is lifted up by the appropriate blower, and the strip can be transported further.

Abb. 2 stellt die Walze D mit den Flächen dt, d2 und Leitern et, e2 dar. Alle Arbeitsgänge, Senken und Heben des Stempels, Transport der Bänder, Weiterschaltung der Walze, Ein- und Ausschalten des Heizstromes sowie Luftzufuhr durch Gebläse, finden zwangsläufig statt. Fig. 2 shows the roller D with the areas dt, d2 and ladders et, e2. All operations, lowering and lifting of the punch, transport of the belts, Switching on the roller, switching the heating current on and off and air supply by blower, take place inevitably.
