Abstract

The invention relates to a method of activating an adhesive film which is applied to a substrate material, by heating before carrying out adhesive bonding with a further material. Rays of heat are produced and are focused on the section of the substrate material on which the adhesive film is to be activated prior to adhesive bonding of a further material. In this context the heat rays are focused by a reflector onto the focal point thereof.

Description

Die Erfindung betrifft ein Verfahren zur Aktivierung eines auf ein Trägermaterial aufgebrachten Klebfilms durch Er­ wärmung vor der Klebung mit einem weiteren Material und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for activating a on an adhesive film applied by Er warming before gluing with another material and a Device for performing the method.

Es ist bekannt, z.B. wetterfeste Textilien an den Nahtstel­ len zusätzlich mit Klebstreifen abzudichten. Diese aus einem Heißkleber bestehenden Klebfilme werden streifenförmig auf das Trägermaterial aufgetragen und vor dem Verbinden mit dem zu beklebenden Material üblicherweise mittels Heißluft er­ wärmt. Das zu beklebende Material wird dann mit dem den er­ wärmten Klebfilm aufweisenden Trägermaterial durch z.B. ein Rollen- oder Walzenwerk geführt und hierbei aufeinanderge­ preßt. Bei diesem Verfahren besteht der Nachteil, daß die Aktivierung des Heißklebers mittels Heißluft sehr energie­ intensiv ist, so daß hohe Energiekosten anfallen.It is known e.g. weatherproof textiles on the seams len also to be sealed with adhesive tape. This one Existing hot-melt adhesive films are formed in strips applied the carrier material and before connecting to the material to be glued usually by means of hot air warms. The material to be glued is then the same as the one he warmed adhesive material comprising e.g. a Roll or roller mill performed and here one another presses. This method has the disadvantage that the Activation of the hot glue by means of hot air very energy is intensive, so that high energy costs are incurred.

Die Aufgabe der Erfindung besteht darin, das Verfahren der eingangs genannten Art so zu verbessern, daß der Energiever­ brauch vermindert wird. Eine weitere Aufgabe der Erfindung besteht darin, eine zur Durchführung des Verfahrens optimale Vorrichtung aufzuzeigen.The object of the invention is the method of to improve the type mentioned so that the energy ver need is reduced. Another object of the invention consists of an optimal one to carry out the procedure Show device.

Erfindungsgemäß erfolgt die Lösung der Aufgabe bezüglich des Verfahrens durch die kennzeichnenden Merkmale des Anspruchs 1 und bezüglich der Vorrichtung durch die kennzeichnenden Merk­ male des Anspruchs 6. Nach der Erfindung ist es möglich, gezielt nur den Flächenbereich zu erwärmen, der zur Akti­ vierung des Heißkleberfilms erwärmt werden muß. Bei Still­ stand der Maschine kann die Vorrichtung leicht wieder außer Betrieb genommen werden. Die Vorrichtung ist somit an Tot­ zeiten der jeweiligen Maschine leichter anzupassen als es bei einer Heißlufterwärmung der Fall ist.According to the invention, the problem is solved with respect to Method by the characterizing features of claim 1 and with regard to the device by the characteristic note male of claim 6. According to the invention it is possible to specifically heat only the area that is to act The hot glue film must be heated. When breastfeeding the machine can easily turn the device out again Be put into operation. The device is therefore dead times of the respective machine easier to adapt than with hot air heating is the case.

Vorteilhafte Ausgestaltungen der Erfindung werden in den abhängigen Ansprüchen beschrieben.Advantageous embodiments of the invention are in the dependent claims described.

In den Zeichnungen ist eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens dargestellt, anhand derer die Erfindung nachstehend näher erläutert wird. Es zeigtIn the drawings, an apparatus for performing the Shown method according to the invention, based on which Invention is explained in more detail below. It shows

Fig. 1 die Vorrichtung in einer schematischen Seitenan­ sicht, Fig. 1 shows the apparatus in a schematic view Seitenan,

Fig. 2 die Vorrichtung nach Fig. 1 in einer schematischen Draufsicht. Fig. 2 shows the device of FIG. 1 in a schematic plan view.

Die Vorrichtung 1 zur Aktivierung eines auf einem Träger­ material 6 befindlichen Klebfilms 7 besteht aus einem Rollen­ werk 3, in dem das Trägermaterial 6 auf das zu beklebende Material 8 gepreßt wird, und einer Heizeinrichtung. Das Trä­ germaterial 6 mit dem Klebfilm 7 befindet sich auf einer Vorratsrolle 2 und wird von dieser abgezogen. Das Rollenwerk 3 besteht aus einer Rolle 4, sowie einer Vorschubrolle 5. Die Vorschubrolle 5 wird mittels einer nicht näher dargestellten Antriebseinrichtung in Rotation versetzt, wobei die Rolle 4 durch Reibung mitgedreht wird. Es ist aber möglich, die Vor­ schubrolle 5 und die Rolle 4 synchron mittels einer gemein­ samen Antriebseinrichtung anzutreiben.The device 1 for activating an adhesive film 7 located on a carrier material 6 consists of a roll mechanism 3 in which the carrier material 6 is pressed onto the material 8 to be glued, and a heating device. The carrier material 6 with the adhesive film 7 is located on a supply roll 2 and is pulled off this. The roller assembly 3 consists of a roller 4 and a feed roller 5 . The feed roller 5 is set in rotation by means of a drive device (not shown in more detail), the roller 4 also being rotated by friction. However, it is possible to drive the thrust roller 5 and the roller 4 synchronously by means of a common drive device.

Die Heizeinrichtung besteht aus einem als Ellipsoidreflektor ausgebildeten Reflektor 12, in dem als Heizstrahler 10 eine fadenförmige Glühlampe 13 angeordnet ist. Durch die besondere Formgebung des Reflektors 12 werden die Wärmestrahlen 14 der Glühlampe 13 auf einen Brennpunkt 11 fokussiert. Der Brenn­ punkt 11 ist dem Flächenabschnitt 9 im Bereich der Rolle 4 zugeordnet, wo eine abschnittsweise Aktivierung des Klebfilms 7 des Trägermaterials 6 vor dem Verkleben mit dem weiteren Material 8 erforderlich ist.The heating device consists of a reflector 12 designed as an ellipsoidal reflector, in which a filament-shaped incandescent lamp 13 is arranged as a radiant heater 10 . Due to the special shape of the reflector 12 , the heat rays 14 of the incandescent lamp 13 are focused on a focal point 11 . The focal point 11 is assigned to the surface section 9 in the area of the roll 4 , where a section-by-section activation of the adhesive film 7 of the carrier material 6 is required prior to bonding with the further material 8 .

Durch die Verwendung des Reflektors 12 in Verbindung mit der Glühlampe 13 ist eine gezielte Erwärmung eines Abschnitts des Trägermaterials 6 möglich, wobei eine Wärmeabstrahlung in die Umgebung vermindert wird. Die Umgebung der Vorrichtung 1 wird somit nur geringfügig erwärmt, wodurch erhebliche Energie­ einsparungen möglich sind. Es hat sich gezeigt, daß der Ein­ satz der Vorrichtung 1 gegenüber bekannten Vorrichtungen zur Aktivierung des Klebfilms eine Verminderung des Energiever­ brauchs um etwa 60% ermöglicht.By using the reflector 12 in connection with the incandescent lamp 13 , a targeted heating of a section of the carrier material 6 is possible, whereby heat radiation into the surroundings is reduced. The area around the device 1 is thus only slightly warmed, whereby considerable energy savings are possible. It has been shown that the use of the device 1 compared to known devices for activating the adhesive film allows a reduction in energy consumption by about 60%.
