Abstract

Synthetic fibre ends which are difficult to heat seal, e.g. polyester calender bands, as well as those of polyamide, are firmly united by an appliance which utilises a heater plate with several points and corresponding holes in a pressure plate. The appliance is hand-operated to press the pressure plate holes over the heated points. It can be used with one hand to produce a first-class seal without tensile stress.

Description

"Verfahren und Vorrichtung zum Verbinden der Enden von aus Kunststoffäden bestehenden Bändern, insbesondere Mangelbändern, durch Schweißen" Bei Nehrwalzen-Muldenmangeln sind mehrere parallel angeordnete und im Abstand über die Länge der Walzen verteilte, sämtliche Walzen umfassende endlose, schmale Mangelbänder vorgesehen, die verhindern, daß sich das Mangel gut um eine Walze wickelt. Diese Mangelbänder reißen häufig, und dann müssen die Enden des gerissenen Bandes oder eines neu einzuziehenden Bandes so mit einander verbunden werden, daß sie eine glatte, nicht auftragende und sich nicht in das Mangelgut eindrückende Fläche bilden."Method and apparatus for joining the ends of plastic threads existing strips, in particular ironer strips, by welding are several parallel arranged and spaced over the length of the rollers, Endless, narrow ironer belts encompassing all of the rollers are provided to prevent that the mangle wraps itself around a roller. These deficiency bands often tear, and then the ends of the torn tape or of a tape that needs to be retracted be connected to one another in such a way that they are smooth, non-bulky and self-contained Do not form a surface that does not press into the defective product.

Thermoplastische, leicht schweißbare Kunststoffbänder sind besonders bei den neuerdings oft angewandten hohen Temperaturen von ca. 1700 bis 2000 C nicht ausreichend hitzebeständig.Thermoplastic, easily weldable plastic tapes are special at the high temperatures of approx. 1700 to 2000 C that have often been used recently sufficiently heat resistant.

Seit einiger Zeit werden daher die Mangelbänder aus Polyesterfäden gewebt, die diesen hohen Temperaturen widerstehen, aber schwer verschweißbar sind, so daß es nicht möglich ist, die aufeinander gelegten Bandenden einfach auf ihrer gesamten Fläche durch Schweißen miteinander zu verbinden.For some time now, ironer tapes have been made from polyester threads woven that can withstand these high temperatures but are difficult to weld, so that it is not possible the stacked ends of the tape easy to connect to one another over their entire surface by welding.

Es ist eine Vorrichtung zum Verbinden der Enden von endlosen Mangelbändern aus schwer verschweißbaren Kunststofffäden durch Schweißen bekannt geworden, die einmal aus einer mit der einen Hand zu bedienenden, zum Festhalten der aufeinander gelegten Bandenden dienenden Zange besteht, deren beide Backen sich deckende Längsschlitze besitzen, und die zum anderen aus einem mit der anderen Hand zu betätigenden lötkolbenähnlichen Heizgerät besteht, dessen beheizte Spitze in den Längsschlitzen der Zangenbacken entlanggezogen wird und dabei in die Bandenden entsprechende Längsschlitze einschmelzt.It is a device for joining the ends of endless ironer belts made of difficult-to-weld plastic threads by welding has become known that once from one to be operated with one hand, to hold on to each other The ends of the tape are used with pliers, the two jaws of which overlap longitudinal slots own, and on the other hand from a soldering iron that can be operated with the other hand There is a heater with its heated tip in the longitudinal slots of the pliers jaws is pulled along and melts corresponding longitudinal slots in the tape ends.

Diese bekannte Vorrichtung ist unhandlich und umständlich zu bedienen, denn man muß, wenn man mit der einen Hand die Zange ergriffen hat, mit der anderen Hand zunächst die Bandenden in die Zange einlegen und dann mit dieser Hand das Heizgerät ergreifen und durch die Längsschlitze in den Zangenbacken entlang ziehen. Außerdem werden die Bandenden beim Durchziehen des Heizgerätes in der Längsrichtung stark beansprucht und können, wenn die Zange nicht ganz fest geschlossen gehalten wird, sich verwerfen und Falten bilden, so daß also einmal die beiden Bandenden keine glatte Fläche bilden und ferner keine gute, glatt durchlaufende Schweißnaht zustande kommt.This known device is unwieldy and awkward to use, for when you have grasped the pliers with one hand you have to use the other Hand first insert the ends of the tape into the pliers and then use this hand to insert the heater grab it and pull it through the longitudinal slots in the jaws of the pliers. aside from that the ends of the tape become strong when the heater is pulled through in the longitudinal direction stressed and can, if the pliers are not held tightly closed, warp and fold, so that once the two ends of the tape are none Form a smooth surface and furthermore no good, smoothly continuous weld seam is achieved comes.

Die Erfindung bezweckt, die Nachteile der bekannten Vorrichtung zu vermeiden und eine einfache, aus einem einzigen handlichen Gerät bestehende, beim Schweißen mit einer Hand zu bedienende Vorrichtung zu schaffen, mit der ohne Zugbeanspruchung der Bandenden beim Schweißen eine einwandfreie Schweißung auch von schwer schweißbaren Kunststoffbändern erzielt wird.The invention aims to address the disadvantages of the known device and avoid a simple one, consisting of a single handy device, when Welding device to be operated with one hand, with the without tensile stress of the strip ends when welding a perfect weld, even of those that are difficult to weld Plastic straps is achieved.

Die Erfindung, die sich auf ein Verfahren zum Verbinden der Enden von aus Kunststoffäden bestehenden Warenbahnen oder Bändern, insbesondere schwer schweißbaren, aus Polyesterfäden bestehenden Mangelbänder, durch Schweißen bezieht, besteht darin, daß die aufeinandergelegten Bandenden auf eine mit mehreren vorzugsweise reihenweise angeordneten Spitzen versehene Heizplatte gelegt werden und mittels einer mit entsprechend den Spitzen in der Heizplatte angeordneten Löchern versehenen, durch eine Handhabe beweglichen Druckplatte in die aufgeheizten Spitzen hineingedrückt werden.The invention, which relates to a method of joining the ends of material webs or tapes consisting of plastic threads, especially heavy weldable ironer bands made of polyester threads, obtained by welding, is that the tape ends placed one on top of the other on one with several preferably rows arranged tips provided heating plate are placed and by means of one provided with holes corresponding to the tips in the heating plate, pressed into the heated tips by a movable pressure plate will.

Eine zur Ausübung des Verfahrens geeignete Vorrichtung besteht darin, daß zwischen Führungen für die Bandenden die mit Spitzen versehene Heizplatte, eine unmittelbar über den Spitzen angeordnete, parallel zur Heizplatte geführte, federnd gelagerte und mit den Spitzen fluchtende Löcher aufweisende Auflegeplatte für die Bandenden angeordnet ist und daß eine in ihrer Ruhelage im Abstand oberhalb der Auflegeplatte befindliche, ebenfalls mit den Spitzen der Heizplatte bzw. den Löchern in der Auflegeplatte entsprechenden Löchern versehene, durch eine Handhabe gegen die Auflegeplatte und die Spitzen bewegbare Druckplatte angeordnet ist.A device suitable for carrying out the procedure consists in: that between guides for the tape ends the pointed heating plate, a spring-loaded, parallel to the heating plate, arranged directly above the tips mounted and aligned with the tips having mounting plate for the Tape ends is arranged and that one in its rest position at a distance above the Support plate located, also with the tips of the heating plate or the holes corresponding holes provided in the support plate, countered by a handle the support plate and the tips movable pressure plate is arranged.

Die Auflegeplatte und die Heizplatte sind in einem Block aus Isolierstoff angeordnet, der außen auf der Vorderseite eines Gehäuses angebracht ist, das zur Sinhandbedienung des Gerätes beim Schweißen an der Unterseite mit einem Zweifingergriff zum Halten des Gerätes und auf der Rückseite mit einem mittels des Daumens zu betätigenden Bedienungsknopf zum Betätigen der Druckplatte trägt.The support plate and the heating plate are in a block made of insulating material arranged, which is mounted on the outside of the front of a housing that is used for Manual operation of the device when welding on the underside with a two-finger grip to hold the device and on the back with a thumb operated Control button for operating the pressure plate carries.

By means of a spring 43, the support rod 28 held with the pressure plate in the illustrated upper rest position.

An der Unterseite des Gehäuses 1 ist ein Zweifinger-Haltegriff 44 angeschraubt, während die Oberseite des Gehäuses 1 einen Geber schalter 45 und ein Signallämpchen 46 trägt. Aus einer Öffnung in einer Seitenwand des Gehäuses ist das die Heiz- und Steuerleitungen enthaltende Kabel 47 herausgeführt.A two-finger handle 44 is located on the underside of the housing 1 screwed while the top of the housing 1 is a transmitter switch 45 and a Signal lamp 46 carries. From an opening in a side wall of the housing the cable 47 containing the heating and control lines is led out.

Zum Zusammenschweißen zweier Bandenden wird das Gerät mittels zweier Finger einer Hand an dem Haltegriff 44 gehalten, wobei die Hand das Gehäuse 1 so umfaßt, daß der Daumen den Bedienungsknopf 34 und den Geberschalter 45 betätigen kann. Dann werden die beiden Bandenden übereinander auf die Auflegeplatte 42 gelegt und in die Spitzen 16 - 19 gedrückt. Darauf wird der Geberschalter 45 kurzzeitig betätigt, wodurch ein Impuls zu dem nicht dargestellten, u. a. einen Transformator enthaltenden, in einem kleinen Gehäuse untergebrachten Elektroteil gegeben und der Stromkreis für die Heizplatte 9 und für das Signallämpchen 46 geschlossen wird. Durch ein Zeitelement im Elektroteil, z.B. ein Bimetallelement, wird nach ca. 6 - 8 Sekunden, die zur Aufheizung der Heizplatte 9 und der Spitzen 11 ausreichen, dieser Stromkreis unterbrochen, was durch Erlöschen des Signallämpchens 46 angezeigt wird. Dann wird mittels des Daumens der Bedienungsknopf 34 heruntergedrückt. Die Druckplatte 24 nimmt am Ende ihrer Abwärtsbewegung die Auflegeplatte 12 und die auf ihr liegenden Bandenden mit und drückt diese in die aufgeheizten Spitzen 11 der Heizplatte 9 hinein. Die Druckplatte 24 wird für 4 - 5 Sekunden in ihrer untersten Stellung gehalten und dann durch Loslassen des Bedienungsknopfes 34 mittels der Feder 43 nach oben bewegt. Die Bandenden sind nun dadurch miteinander verschweißt, daß sich um die Ränder der von den Spitzen 11 in die Bandenden geschmolzenen Löcher ein Schmelzring bildet, der einen sicheren Verbund der beiden Bandenden bewirkt. Da beim Herunterdrücken der Druckplatte der Stromkreis für die Heizplatte unterbrochen ist, kühlt sich diese während der Schweißzeit von 4 - 5 Sekunden die Heizplatte 9 genügend ab, um ein sicheres Lösen der Spitzen aus den in die Bandenden geschmolzenen Löcher zu gewährleisten. Außerdem hat dieses Verfahren den Vorteil, daß auch bei zu langem Heruntergedrückthalten der Druckplatte es nicht zu einem Verbrennen der Bandenden kommen kann.To weld two ends of the tape together, the device is activated by means of two Finger of one hand held on the handle 44, the hand holding the housing 1 so comprises that the thumb actuate the control button 34 and the control switch 45 can. Then the two ends of the tape are placed on top of each other on the support plate 42 and pressed into the tips 16-19. The transmitter switch 45 is thereupon briefly actuated, whereby a pulse to the not shown, inter alia. a transformer contained, given in a small housing housed electrical part and the Circuit for the heating plate 9 and for the signal lamp 46 is closed. With a time element in the electrical part, e.g. a bimetal element, after approx - 8 seconds, which are sufficient to heat the heating plate 9 and the tips 11, this circuit is interrupted, which is indicated by the signal lamp 46 going out will. Then the control button 34 is depressed by means of the thumb. the Pressure plate 24 takes the support plate 12 and the at the end of its downward movement on the tape ends lying on it and presses them into the heated tips 11 the heating plate 9 into it. The pressure plate 24 is for 4 - 5 seconds in its lowest Position held and then by releasing the control button 34 by means of the Spring 43 moved up. The ends of the belt are now welded together, that around the edges of the holes melted from the tips 11 into the ribbon ends forms a melting ring that creates a secure bond between the two ends of the tape. Since the circuit for the heating plate is interrupted when the pressure plate is pressed down is, this cools the heating plate during the welding time of 4 - 5 seconds 9 enough to reliably loosen the tips from the ends of the tape melted Holes to ensure. In addition, this method has the advantage that even with Holding the pressure plate down for too long will not burn the Tape ends can come.

Wenn das Gerät zum Verschweißen der Enden von Mangelbändern verwendet wird, kann es statt von Hand gehalten zu werden, auch auf einer zu den Nangelwalzen parallelen, am Maschinengestell oder an einem besonderen Gestell angebrachten Führungsstange verschiebbar gelagert sein, so daß es nacheinander in die Stellungen gebracht werden kann, die die parallel laufenden, über die Länge der Walzen verteilt angeordneten Mangelbänder einnehmen.When the device is used to weld the ends of ironer tapes instead of being held by hand, it can also be held on one of the nishing rollers parallel guide rod attached to the machine frame or to a special frame be slidably mounted so that it can be successively brought into the positions can, which are arranged in parallel, distributed over the length of the rollers Take deficiency bands.

Das Gerät kann auch zum Heißkleben von Bandenden mittels eines zwischengelegten Klebestreifens verwendet werden, beispielsweise zum Heißkleben von besonders hochhitzebeständigen Bändern, z.B. aus Polyamid oder Polymid, die Temperaturen von 1600 bis ca. 2300 C standh#1.ten.The device can also be used to heat glue tape ends by means of an interposed Adhesive strips can be used, for example for hot gluing particularly high-temperature resistant Tapes, e.g. made of polyamide or polymide, the temperatures from 1600 to approx. 2300 C standh # 1.ten.

Hierzu ist die mit Spitzen versehene Heizplatte gegen eine Heizplatte mit glatter Oberfläche auszutauschen, wobei die Auflegeplatte entfällt. Die obere Druckplatte kann dabei zusätzlich auch aufheizbar gestaltet werden.For this purpose, the hot plate provided with tips is against a hot plate to be exchanged with a smooth surface, whereby the support plate is omitted. The upper The printing plate can also be designed so that it can be heated.
