Description

BESCHREIBUNG DESCRIPTION

Die vorliegende Erfindung betrifft eine mindestens zwei stossverbundene Teile aufweisende Kunststoffolienbahn. The present invention relates to a plastic film web having at least two butt-connected parts.

Es ist bekannt, Kunststoffolienbahnen, weichein der Produktion eine gewisse Breite, normalerweise 2m aus herstellungstechnischen Gründen, nicht überschreiten, durch Schweissung oder durch Klebung miteinander zu verbinden, um grössere Bahnbreiten zu erreichen. It is known to connect plastic film webs which do not exceed a certain width in production, normally 2 m for manufacturing reasons, by welding or by gluing in order to achieve larger web widths.

Eine derartige Verbindung muss als sog. Überlappverbindung hergestellt werden, da eine Stossverbindung, wie sie beim Schweissen von Blechen bekannt ist, bei Kunststoffolien bisher aus Festigkeitsgründen nicht möglich war. Wenn auch ein derartiges Stumpf verbinden versucht wurde, beispielsweise mittels sog. Schweissschnüre, konnten diese Verbindungen nichtbefrie-digen, da sie festigkeitsmässig die an sie gestellten Anforderungen nicht zu erfüllen vermochten. Such a connection has to be established as a so-called overlap connection, since a butt connection, as is known when welding sheet metal, was previously not possible for reasons of strength in plastic films. Even if such a stump was attempted to be connected, for example by means of so-called welding cords, these connections could not be satisfied because they could not meet the requirements placed on them in terms of strength.

Wenn auch die Überlappverbindungen festigkeitsmässig den Anforderungen genügen, so weisen sie doch den grossen Nachteil auf, dass im Bereich der Überlappung die Dicke der Kunststoffolienbahn verdoppelt wird. Da der Trend nach dickeren Folien geht, wirkt sich diese Dickenverdoppelung immer unangenehmer aus, indem ein Aufrollen derartiger Folienbahnen in annehmbarer Form kaum mehr möglich ist. Even though the overlap connections meet the requirements in terms of strength, they have the major disadvantage that the thickness of the plastic film web is doubled in the area of the overlap. Since the trend is towards thicker films, this doubling of thickness is becoming increasingly unpleasant, since it is hardly possible to roll up such film webs in an acceptable form.

Es wurde zwar versucht, durch sog. Anschiften der zu verbindenden Ränder diesen Dickensprung zu verhüten, was sich aber ausserordentlich kostspielig auf die Herstellung derartiger Kunststoffolienbahnen auswirkt und infolge der äussersten dünnen Randpartien der geschifteten Teile, insbesondere beim Schweissen, gewisse Schwierigkeiten auftraten. Attempts have been made to prevent this change in thickness by so-called pushing on the edges to be connected, but this has an extraordinarily costly effect on the production of such plastic film webs and, as a result of the outermost thin edge parts of the parts to be written, in particular during welding, certain difficulties arose.

Die vorliegende Erfindung bezweckt eine Kunststoffolienbahn, die sich aus mindestens zwei stossverbundenen Teilen zusammensetzt, festigkeitsgerecht herzustellen und damit für die Technik unter den gegebenen Vorschriften anwendbar zu gestalten. The present invention aims to produce a plastic film web, which is composed of at least two butt-bonded parts, in accordance with the strength and thus to make it applicable for the technology under the given regulations.

Dieser Zweck kann erfindungsgemäss dadurch erreicht werden, dass die Stosslinien der beiden Teile mindestens auf einem This purpose can be achieved according to the invention in that the butt lines of the two parts on at least one

Teil ihrer Länge gebogen und/oder gebrochen ausgebildet sind. Part of their length are bent and / or broken.

Auf diese Weise entsteht anstelle der bekannten gradlinigen linearen Stösse eine Stossverbindung mit zweidimensionalem Verlauf der Stosslinien, wodurch die entsprechenden Festigkeits-s Vorschriften im Nahtbereich für derartige Folienbahnen einhaltbar werden. In this way, instead of the known straight-line linear joints, a butt joint with a two-dimensional course of the butt lines is created, as a result of which the corresponding strength requirements in the seam area for such film webs can be met.

Die Erfindung wird anschliessend beispielsweise anhand einer Zeichnung erläutert. The invention is subsequently explained, for example, using a drawing.

Die Verbindung dieser Folien 2 und 3 kann durch deren Zusam-25 menschweissen an den Stosslinien 5 und 6 erfolgen. Bestehen die Folien beispielsweise aus Polyäthylen, so sind diese Bereiche der Stosslinien 5 und 6 auf Temperaturen im Schmelzbereich zu erhöhen, so dass die Ränder ineinander überfliessen und damit eine zugstarke Verbindung ergeben, welche, durch die Form-30 schlüssigkeit und die Länge der verbindenden Schweisslinien bedingt, den Anforderungen bezüglich Zugfestigkeit genügen. 1 and 2 show a plastic film web 1 in the cutout, which is composed of two plastic films 2 and 3. The edges of these foils 2 and 3 are formed as merging lines 5 20 and 6 and are produced, for example, by means of punching tools. These butt lines 5 and 6 define free edges of the films 2 and 3, which interlock and thus form a positive connection a priori. These foils 2 and 3 can be connected by joining them together at the butt lines 5 and 6. If the foils are made of polyethylene, for example, these areas of the butt lines 5 and 6 should be raised to temperatures in the melting range so that the edges overlap and thus create a strong connection, which, due to the form-fitting nature and the length of the connecting welding lines conditionally, meet the requirements regarding tensile strength.

Es ist dabei möglich, diese mäanderförmigen gebogenen Stosslinien zusätzlich zu zahnen oder zu kerben, womit insbesondere die Schweissnahtlänge weiterhin verlängert wird, was sich 35 positiv auf den Zusammenhalt der beiden Folien 2 und 3 auswirkt. It is possible to additionally tooth or notch these meandering curved butt lines, which in particular further extends the weld seam length, which has a positive effect on the cohesion of the two foils 2 and 3.

Wie Fig. 2 zeigt, ist es auf diese Weise möglich, Folien miteinander zu verbinden, welche keine merkliche Verdickung ergeben, d. h. welche im Sinne von Blechen im Stoss und nicht in 40 Überlappung verbunden werden können. As shown in FIG. 2, it is possible in this way to connect foils to one another which do not result in a noticeable thickening, i. H. which can be joined in the sense of sheets in the joint and not in an overlap.

Eine weitere Ausführungsmöglichkeit zeigt Fig. 3, welche grundsätzlich gleich aufgebaut ist bezüglich Stosslinien, wie die Fig. 1 und 2. Die hier dargestellte Kunststoffolienbahn 8 besteht ebenfalls aus zwei Kunststoffolien 9 und 10 - es können natürlich 45x-beliebige Folienanzahlen auf diese Art miteinander verbunden werden- wobei die beiden Stosslinien 12 und 13 nicht aneinan-derstossen, sondern einen Zwischenraum 14 freilassen, in den beispielsweise eine Verbindungspaste, insbesondere ein sog. Plastisol, eingebracht werden kann, worauf das Ganze erhitzt so und die beiden Folien 9 und 10 miteinander verbunden werden und dann die nötige Zugfestigkeit aufweisen. Bei der dargestellten Ausführung ist ferner ein Kunststoffband 16 als mögliche Verstärkung auf der einen Seite - es kann auch beidseitig sein-aufgebracht, dasz. B. aus Kevlar oder Polyester od. dgl., besteht 55und beschichtet sein kann. Bei dieser Ausführung ist die Dicke im Bereich der Verbindungsstelle durch das Anbringen des Kunststoffbandes 16 etwas angewachsen, jedoch im Verhältnis zur Dicke bei Überlappschweissungen immer noch sehr klein. 3 shows a further possible embodiment, which is basically constructed in the same way with respect to butt lines as FIGS. 1 and 2. The plastic film web 8 shown here also consists of two plastic films 9 and 10 - it is of course possible to connect any number of films in this way to one another the two butt lines 12 and 13 do not abut each other, but leave a space 14 into which, for example, a connecting paste, in particular a so-called plastisol, can be introduced, whereupon the whole thing is heated and the two foils 9 and 10 are connected to one another and then have the necessary tensile strength. In the embodiment shown, a plastic band 16 is also applied as a possible reinforcement on one side - it can also be on both sides, that is. B. Kevlar or polyester or the like., There is 55and can be coated. In this embodiment, the thickness in the area of the connection point has increased somewhat due to the application of the plastic band 16, but is still very small in relation to the thickness in the case of overlap welds.

Die Fig. 5 bis 8 zeigen weitere Möglichkeiten der Ausbildung 60von Stosslinien 20-23, welche hier als gebrochene Linien ausgebildet sind. Dabei zeigt Fig. 5 ein sog. Schwalbenschwanzverbindung, d. h. eine formschlüssige Verbindung, während die Fig. 6, 7 und 8 durch die Schweissverbindung zu kraftschlüssigen Verbindungen gemacht werden. 5 to 8 show further possibilities for the formation 60 of butt lines 20-23, which are designed here as broken lines. 5 shows a so-called dovetail connection, i. H. a positive connection, while FIGS. 6, 7 and 8 are made by the welded connection to positive connections.

65 Es ist auch hier möglich, durch entsprechende Zahnung das Ineinandergreifen zu verbessern und formschlüssig zu gestalten. 65 It is also possible here to improve the interlocking by means of appropriate toothing and to design it in a form-fitting manner.

Auf diese Weise ist es möglich, bei optimalen Fabrikationsbedingungen von beispielsweise 2 m breiten Bahnen, Kunststoff In this way it is possible, with optimal manufacturing conditions of, for example, 2 m wide webs, plastic

bahnen, besonders aus thermoplastischem Material, mühelos in irgend einer Breite endlos oder genau flächenmässig dimensioniert zu erstellen, ohne dass dafür maschinelle Schwierigkeiten enstehen. Aufgrund der Ausbildung der Stosslinien in gebogener und/oder gebrochener Form, können die verlangten Zugfestigkeiten erreicht werden, was beider Stossschweissung, z. B. mittels Schweissschnüren bei geraden Stosslinien nicht erreichbar ist. webs, especially made of thermoplastic material, can be easily and endlessly dimensioned in any width without creating mechanical difficulties. Due to the formation of the butt lines in a curved and / or broken shape, the required tensile strengths can be achieved, which both butt welding, z. B. is not reachable by welding cords at straight butt lines.

Bei den Kunststoffolien kann es sich um armierte oder nicht armierte Folien handeln. Grundsätzlich ändert an den vorbeschriebenen Tatsachen nichts. The plastic films can be armored or non-armored films. Basically, nothing changes in the facts described above.
