Description

Die Erfindung betrifft eine Vorrichtung zum Applizieren eines mit einem Haftvermittler versehenen endlosen Streifens auf eine Endlosbahn gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for applying a with an endless strip provided with an adhesion promoter an endless web according to the preamble of claim 1.

Eine derartige Vorrichtung ist zum Beispiel aus der DE 32 10 551 A1 bekannt, wo eine Endlosbahn zusammen mit einem endlosen Streifen über einen Heißsiegelzylinder geführt werden und dabei von Andrückrollen an den Heißsiegelzylinder angedrückt werden. Durch die Wärme des Heißsiegelzylinders wird der thermosensitive Haftvermittler sensibilisiert, so dass der endlose Streifen mit der Endlosbahn verklebt werden kann.Such a device is for example from DE 32 10 551 A1 known where an endless path along with an endless Strips are passed over a heat seal cylinder and pressed against the heat-sealing cylinder by pressure rollers become. Due to the heat of the heat sealing cylinder thermosensitive adhesion promoter sensitized so that the endless strips can be glued to the endless web.

Eine weitere Vorrichtung ist aus der DE 195 11 698 C1 bekannt, wo ein Endlosstreifen mit einer Endlosbahn dadurch verklebt wird, dass der Energieeintrag über eine Ultraschallsonotrode erfolgt.Another device is known from DE 195 11 698 C1, where an endless strip sticks to an endless web is that the energy input through an ultrasonic sonotrode he follows.

Die oben genannten Vorrichtungen haben den Nachteil, dass sie zum einen relativ aufwendig sind, zum anderen der Energieeintrag (Wärme oder Ultraschall) nicht nur in den endlosen Streifen, sondern auch in die Endlosbahn erfolgt, was u. U. zu Problemen in der Endlosbahn führen kann. The above devices have the disadvantage that they on the one hand are relatively complex, on the other hand the Energy input (heat or ultrasound) not only in the endless stripes, but what happens in the endless web u. U. can lead to problems in the endless web.  

Weitere Vorrichtungen zum Erwärmen eines Streifens oder einer endlosen Bahn sind aus der US 4 737 213, der DE-AS 21 01 232, der DE 91 14 932 U1 und der DE 32 07 823 A1 bekannt. Bei diesen Vorrichtungen ist aber nicht sichergestellt, dass die Endlosbahn und/oder der endlose Streifen bei Stillstand der Maschine keinen Schaden nehmen.Other devices for heating a strip or a endless web are from US 4,737,213, DE-AS 21 01 232, known from DE 91 14 932 U1 and DE 32 07 823 A1. At However, these devices are not guaranteed that the Endless web and / or the endless strip when the Take no damage to the machine.

Aus der JP 62-033 625 A ist eine Vorrichtung bekannt geworden, mit der lediglich ein zu applizierender Streifen erwärmt wird. Auch hier tritt das Problem auf, dass bei Stillstand der Maschine oder langsamem Vorschub der Streifen Schaden nehmen, d. h. überhitzt werden kann.A device has become known from JP 62-033 625 A, with which only a strip to be applied is heated. The problem also arises here that when the Machine or slow feed of the strips, d. H. can be overheated.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszugestalten, dass beim Applizieren eines endlosen Streifens auf eine Endlosbahn die Endlosbahn und/oder der endlose Steifen keinen Schaden nimmt.The invention is therefore based on the object To design the device of the type mentioned in such a way that when applying an endless strip to an endless web the endless path and / or the endless stiffener do no damage takes.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of Claim 1 solved.

Wird lediglich der mit dem Haftvermittler versehene endlose Streifen erwärmt und dieser erwärmte endlose Streifen auf die Endlosbahn aufgebracht, dann erfolgt die Verbindung von Streifen und Endlosbahn ohne dass die Endlosbahn nachteilig beeinflusst wird. Es kann somit auch ein thermosensitives Papier als Endlosbahn verwendet werden, ohne dass die sensitive Schicht sensibilisiert wird. Mit der erfindungsgemäßen Vorrichtung wird die Energie lediglich in den Bereich eingetragen, die den Haftvermittler aufweist.Is only the endless provided with the adhesion promoter Strip heated and this heated endless strip on the Continuous web applied, then the connection of Strip and endless web without the endless web being disadvantageous being affected. It can also be a thermosensitive Paper can be used as a continuous web without the sensitive layer is sensitized. With the device according to the invention, the energy is only in entered the area that has the adhesion promoter.

Vor dem Einlauf in den Heizschuh ist erfindungsgemäß eine Umlenkwelle vorgesehen, mit welcher der endlose Streifen vom Heizschuh abgehoben bzw. auf diesen aufgesetzt werden kann, so dass bei Stillstand der endlose Streifen nicht überhitzt wird. According to the invention, one is before the entry into the heating shoe Deflection shaft provided with which the endless strip from Heating shoe can be lifted off or placed on it, so that the endless strip is not overheated when it stops.  

Die Vorteile der erfindungsgemäßen Vorrichtung bestehen darin, dass sie relativ preisgünstig ist, aus einer geringen Anzahl von Bauteilen besteht, leicht nachrüstbar ist, dass sie für eine Vielzahl unterschiedlicher Endlosbahnen, d. h. für thermosensitives Papier und normales Papier verwendbar ist und dass sie bedienungsfreundlich ist.The advantages of the device according to the invention are that it is relatively inexpensive, from a small number of components, it is easy to retrofit that they for a variety of different endless webs, i.e. H. For thermosensitive paper and normal paper can be used and that it is easy to use.

Bei der erfindungsgemäßen Vorrichtung kann das Gegenwerkzeug von einer Welle gebildet sein, die angetrieben oder nicht angetrieben ist. Außerdem kann diese Welle als Vollwelle oder als Hohlwelle ausgebildet sein, wobei die Hohlwelle ein geeignetes Medium aufweisen kann, so dass sie zum Kühlen oder Heizen verwendbar ist. Vorteilhaft weist der Heizschuh eine Führungsnut für den endlosen Streifen auf und/oder ist mit einem eingebauten Heizelement versehen. Die Temperatur des Heizschuhs kann über ein Steuer- oder Regelgerät eingestellt werden. Als endloser Streifen kann ein Folienband, ein Magnetband oder dergleichen verwendet werden. Ferner ist die Anpressrolle in Richtung auf das Gegenwerkzeug einstellbar und mit einstellbarem Druck anpressbar.In the device according to the invention, the counter tool be formed by a shaft that is driven or not is driven. In addition, this wave can be a solid wave or be designed as a hollow shaft, the hollow shaft suitable medium, so that they can be used for cooling or Heating is usable. The heating shoe advantageously has one Guide groove for the endless strip on and / or is with provided with a built-in heating element. The temperature of the The heating shoe can be set via a control or regulating device become. A film strip can be used as an endless strip Magnetic tape or the like can be used. Furthermore, the Pressure roller adjustable in the direction of the counter tool and can be pressed on with adjustable pressure.
