Description
Die vorliegende Erfindung betrifft eine mindestens zwei
stossverbundene Teile aufweisende Kunststoffolienbahn.
Es ist bekannt, Kunststoffolienbahnen, welche in der
Produktion eine gewisse Breite, normalerweise 2 m aus
herstellungstechnischen Gründen, nicht überschreiten,
durch Schweissung oder durch Klebung miteinander zu
verbinden, um grössere Bahnbreiten zu erreichen.
Eine derartige Verbindung muss als sog. Ueberlappver
bindung 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 Stumpfverbinden
versucht wurde, beispielsweise mittels sog. Schweiss
schnüre, konnten diese Verbindungen nicht befriedigen,
da sie festigkeitsmässig die an sie gestellten Anforde
rungen nicht zu erfüllen vermochten.
Wenn auch die Ueberlappverbindungen festigkeitsmässig
den Anforderungen genügen, so weisen sie doch den gros
sen Nachteil auf, dass im Bereich der Ueberlappung 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.
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 ge
schifteten Teile, insbesondere beim Schweissen, gewisse
Schwierigkeiten auftraten.
Die vorliegende Erfindung bezweckt eine Kunststoffolien
bahn, die sich aus mindestens zwei stossverbundenen
Teilen zusammensetzt, festigkeitsgerecht herzustellen
und damit für die Technik unter den gegebenen Vorschrif
ten anwendbar zu gestalten.
Dieser Zweck kann erfindungsgemäss dadurch erreicht
werden, dass die Stosslinien der beiden Teile minde
stens auf einem Teil ihrer Länge gebogen und/oder ge
brochen ausgebildet sind.
Auf diese Weise entsteht anstelle der bekannten grad
linigen linearen Stösse eine Stossverbindung mit zwei
dimensionalem Verlauf der Stosslinien, wodurch die ent
sprechenden Festigkeitsvorschriften im Nahtbereich für
derartige Folienbahnen einhaltbar werden.
Die Erfindung wird anschliessend beispielsweise anhand
einer Zeichnung erläutert.
Es zeigen:
Fig. 1, 3, 5 bis 8 Ausschnitte aus sechs unterschiedlichen
Kunststoffolienbahnen, zusammengesetzt aus zwei
stossverbundenen Kunststoffolien, in Aufsicht,
Fig. 2 einen Schnitt durch die Kunststoffolienbahn
nach Fig. 1, gemäss Schnittlinie A-A,
Fig. 4 einen Schnitt gemäss Schnittlinie B-B der
Fig. 3, mit zusätzlichem Kunststoffband.
Die Fig. 1 und 2 zeigen eine Kunststoffolienbahn 1 im
Ausschnitt, welche sich aus zwei Kunststoffolien 2 und
3 zusammensetzt. Die Ränder dieser Folien 2 und 3 sind
als Stosslinien 5 und 6 mäanderförmig ausgebildet und
beispielsweise mittels Stanzwerkzeugen hergestellt.
Diese Stosslinien 5 und 6 legen freie Ränder der Folien
2 und 3 fest, die ineinandergreifen und damit a priori
eine formschlüssige Verbindung bilden. Die Verbindung
dieser Folien 2 und 3 kann durch deren Zusammenschweis
sen an den Stosslinien 5 und 6 erfolgen. Bestehen die
Folien beispielsweise aus Polyaethylen, 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 Formschlüssigkeit und die Länge der
verbindenden Schweisslinien bedingt, den Anforderungen
bezüglich Zugfestigkeit genügen.
Es ist dabei möglich, diese mäanderförmigen gebogenen
Stosslinien zusätzlich zu zahnen oder zu kerben, womit
insbesondere die Schweissnahtlänge weiterhin verlängert
wird, was sich positiv auf den Zusammenhalt der beiden
Folien 2 und 3 auswirkt.
Wie Fig. 2 zeigt ist es auf diese Weise möglich, Folien
miteinander zu verbinden, welche keine merkliche Ver
dickung ergeben, d.h. welche im Sinne von Blechen im
Stoss und nicht in Ueberlappung verbunden werden
können.
Eine weitere Ausführungsmöglichkeit zeigt Fig. 3, wel
che grundsätzlich gleich aufgebaut ist bezüglich Stoss
linien, wie die Fig. 1 und 2. Die hier dargestellte
Kunststoffolienbahn 8 besteht ebenfalls aus zwei Kunst
stoffolien 9 und 10 - es können natürlich x-beliebige
Folienanzahlen auf diese Art miteinander verbunden wer
den - wobei die beiden Stosslinien 12 und 13 nicht
aneinanderstossen, sondern einen Zwischenraum 14 frei
lassen, in den beispielsweise eine Verbindungspaste,
insbesondere ein sog. Plastisol, eingebracht werden
kann, worauf das Ganze erhitzt 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 mögli
che Verstärkung auf der einen Seite - es kann auch
beidseitig sein - aufgebracht, das z.B. aus Kevlar,
oder Polyester o. dgl. besteht und beschichtet sein
kann. Bei dieser Ausführung ist die Dicke im Bereich
der Verbindungsstelle durch das Anbringen des Kunst
stoffbandes 16 etwas angewachsen, jedoch im Verhältnis
zur Dicke bei Ueberlappschweissungen immer noch sehr
klein.
Die Fig. 5 bis 8 zeigen weitere Möglichkeiten der Aus
bildung von Stosslinien 20-23, welche hier als ge
brochene Linien ausgebildet sind. Dabei zeigt Fig. 5
eine sog. Schwalbenschwanzverbindung, d.h. eine form
schlüssige Verbindung, während die Fig. 6 , 7 und 8
durch die Schweissverbindung zu kraftschlüssigen Ver
bindungen gemacht werden.
Es ist auch hier möglich, durch entsprechende Zahnung
das Ineinandergreifen zu verbessern und formschlüssig
zu gestalten.
Auf diese Weise ist es möglich, bei optimalen Fabrika
tionsbedingungen von beispielsweise 2 m breiten Bahnen,
Kunststoffbahnen, besonders aus thermoplastischem Mate
rial, mühelos in irgend einer Breite endlos oder genau
flächenmässig dimensioniert zu erstellen, ohne dass
dafür maschinelle Schwierigkeiten entstehen. Aufgrund
der Ausbildung der Stosslinien in gebogener und/oder
gebrochener Form, können die verlangten Zugfestigkeiten
erreicht werden, was bei der Stossschweissung, z.B.
mittels Schweissschnüren bei geraden Stosslinien nicht
erreichbar ist.
Bei den Kunststoffolien kann es sich um armierte oder
nicht armierte Folien handeln. Grundsätzlich ändert
an den vorbeschriebenen Tatsachen nichts.
Alle in der Beschreibung und/oder den Figuren dargestell
ten Einzelteile und Einzelmerkmale sowie deren Permu
