Die
Der Erfindung liegt die Aufgabe zugrunde, einen Trichterbeutel, insbesondere einen Topfpflanzentrichter der eingangs genannten Art zu schaffen sowie ein Verfahren zum fortlaufenden Herstellen eines solchen Trichterbeutels bzw. eines Topfpflanzentrichters vorzuschlagen, das durch eine spezielle ausgebildete bodenseitige Quernaht eine wesentliche Qualitätsverbesserung ermöglicht, insbesondere wenn diese Trichterbeutel zum Transport von gewässerten Topfpflanzen verwendet werden. Zugleich soll eine Vorrichtung geschaffen werden, durch die mit baulich einfachen Mitteln eine sicher zu handhabender Trichterbeutel, speziell ein Topfpflanzentrichter, erzielt wird.The The invention has for its object a funnel bag, in particular to create a pot plant funnel of the type mentioned above and a process for the continuous production of such a funnel bag or to propose a pot plant funnel that is trained by a special bottom-side cross seam enables a significant quality improvement, especially when these funnel bags are used to transport watered Potted plants can be used. At the same time, a device is to be created become a safe to use with structurally simple means Funnel bag, especially a pot plant funnel, is achieved.
Um den Anforderungen an einen derart beschaffenen Trichterbeutel bzw. einen Topfpflanzentrichter Rechnung zu tragen, wird erfindungsgemäß vorgeschlagen, daß die Bodennaht von einer Klebenaht gebildet ist. Hier bietet sich vor allen Dingen eine Hot-Melt-Klebung an, die vorzugsweise von einem sich zumindest zwischen den Seitenschweißnähten der Trichterbeutel durchgehend erstreckenden, vorzugsweise transparenten Klebestreifen gebildet ist. Dieser Klebestreifen kann sich im wesentlichen parallel zum bodenseitigen Rand der Trichterbeutel erstrecken oder aber einen frei wählbaren Verlauf zwischen den Seitenschweißnähten aufweisen, beispielsweise im wesentlichen V-förmig ausgebildet sein. Neben einer absoluten Flüssigkeitsdichtigkeit wird auch weitgehend jegliche Schrumpfung im Quernahtbereich verhindert. Schließlich ergibt sich eine bessere Optik, wenn ein transparenter Hot-Melt-Kleber verwendet wird.Around the requirements for such a funnel bag or Taking into account a pot plant funnel is proposed according to the invention, that the Bottom seam is formed by an adhesive seam. Here offers itself hot melt bonding to everything on, which is preferably at least between the side welds of the Hopper bag extending continuously, preferably transparent Adhesive tape is formed. This tape can be essentially extend parallel to the bottom edge of the funnel bag or but a freely selectable one Have course between the side welds, for example be substantially V-shaped. In addition to absolute liquid tightness also largely prevented any shrinkage in the cross seam area. Finally there is a better look if a transparent hot-melt adhesive is used.
Von besonderer Bedeutung für die vorliegende Erfindung ist der Umstand, daß Endbereiche des Klebestreifens an der Einfüllseite der Trichterbeutel im Bereich deren Seitenschweißnähte als Einreißschutz dienen. Da der Abstand des Klebestreifens zum bodenseitigen Rand der Trichterbeutel und der Abstand der Klebestreifen-Endbereiche zum einfüllseitigen Rand der Trichterbeutel gleich ausgebildet ist, hat man den Vorteil, daß man bei um 180° versetzter Lage der Topfpflanzentrichter bildenden Bahnabschnitte mit einem Arbeitsvorgang sowohl einen weitgehend dichten Verschluß am Boden der Trichterbeutel und einen relativ einfach herzustellenden Einreißschutz im Bereich der Einfüllseite der Trichterbeutel erreicht.Of particular importance for the present invention is the fact that end regions of the adhesive strip on the filling side of the funnel bags serve as tearing protection in the region of their side weld seams. Since the distance of the adhesive strip to the bottom edge of the funnel bag and the distance of the adhesive strip end regions to the filling-side edge of the funnel bag is of the same design, it has the advantage that when the web sections forming the pot plant funnels are offset by 180.degree Closure at the bottom of the funnel bag and a relatively easy to manufacture reached the tear protection in the area of the filling side of the funnel bags.
Ein derartiger Trichterbeutel bzw. ein Topfpflanzentrichter der vorgenannten Art läßt sich verfahrensmäßig entsprechend dem Vorschlag nach der Erfindung aus zwei flach aufeinanderliegenden Bahnen aus thermoplastischem Kunststoff dann besonders einfach herstellen, wenn die beiden Bahnen im Bereich einer Bearbeitungsstation zumindest an ihren Randseiten auf gegenseitigen Abstand gebracht werden, auf die Innenseite wenigstens einer der beiden Bahnen in der Nähe des bodenseitigen Randes der Trichterbeutel ein zumindest den Abstand zwischen den beiden in einer Quertrennschweißstation gebildeten Seitennähte jeweils eines Trichterbeutels überbrückender Kleber aufgebracht wird und danach die beiden Bahnen wieder zusammengebracht werden.On such a funnel bag or a pot plant funnel of the aforementioned Kind can be procedurally accordingly the proposal according to the invention from two lying flat Then make sheets of thermoplastic material particularly easily, if the two webs at least in the area of a processing station are brought at a mutual distance on their edges the inside of at least one of the two webs near the bottom Edge of the funnel bag at least the distance between the both formed in a cross cut welding station side seams one funnel bag each bridging Glue is applied and then brought the two sheets back together become.
Da Trichterbeutel bzw. Topfpflanzentrichter der hier interessierenden Art in der Regel dadurch hergestellt werden, daß im Kunststoffolienband wechselweise um 180° versetzt Trichterbeutel hergestellt werden, ist es sehr leicht, den Kleber um ein geringes Stück über die einzubringenden Seitennähte eines zu bildenden Trichterbeutels hinaus bis in die jeweils in der Bahn benachbarte, also um 180° versetzt angeordnete Trichterbeutel aufzubringen. Dies bringt den immensen Vorteil mit sich, daß im gleichen Arbeitsgang sowohl eine dichte Bodennaht im unteren Bereich der Trichterbeutel als auch ein Einreißschutz im oberen Bereich der Trichterbeutel erzielt werden kann.There Funnel bags or potted plant funnels of those interested here Kind usually be made by alternately in the plastic film tape offset by 180 ° Funnel bags are made, it is very easy to use the glue a little way over the side seams to be introduced funnel bag to be formed up to each in the web neighboring, i.e. offset by 180 ° to arrange arranged funnel bags. This brings the immense Advantage with itself that in same operation both a tight bottom seam in the lower area the funnel bag as well as a tear protection in the upper area of the Funnel bags can be achieved.
Selbstverständlich ist es auch möglich, die Bodennaht nicht parallel im Abstand zum bodenseitigen Rand der Trichterbeutel anzuordnen. Vielmehr kann diese alle möglichen Konturen, beispielsweise in Form eines V usw. annehmen. Optimal ist eine solche Herstellung vor allen Dingen dann, wenn die Formkonturen des Klebestreifens in Abhängigkeit eines voreinstellbaren Steuerprogramms erzeugt werden. Eine Vorrichtung zum fortlaufenden Herstellen von Trichterbeuteln, insbesondere Topfpflanzentrichtern aus zwei flach aufeinanderliegenden Bahnen aus thermoplastischem Kunststoff mit Bearbeitungsstationen in Form von Stanzeinrichtungen und einer Bodennahtbildungseinrichtung sowie mit einer Quertrennschweißstation und einer Aufnadelstation zeichnet sich dadurch aus, daß die Bodennahtbildungseinrichtung einen Klebemittel abgebenden, steuerbaren Geber aufweist. Dieser ist vorzugsweise mit einer Austrittsdüse ausgerüstet, die nach Aufrichten der außenliegenden Bereiche der beiden Bahnen in den dadurch gebildeten Öffnungsbereich einfährt und auf einen zeitlich und/oder örtlich fest einstellbaren oder nach einem Programm einstellbaren Ablauf innerhalb dieses Bereiches die Klebenaht auf die Innenseite der einen Bahn aufbringt.It goes without saying it also possible the bottom seam is not parallel to the bottom edge of the To arrange the funnel bag. Rather, it can do all sorts Take contours, for example in the form of a V, etc. Optimal is such a production especially when the shape contours depending on the adhesive strip of a presettable control program. A device for the continuous production of funnel bags, especially pot plant funnels made of two thermoplastic sheets lying flat on top of each other Plastic with processing stations in the form of punching devices and a bottom seam formation device as well as with a cross cut welding station and a needle station is characterized in that the bottom seam formation device has a controllable transmitter which delivers adhesive. This is preferably equipped with an outlet nozzle which, after erecting the outer one Areas of the two tracks in the opening area formed thereby retracts and at a time and / or location fixed or adjustable according to a program within this area the adhesive seam on the inside of the brings up a web.
