Method and device for attaching a sheet or a Foil on an underlayer.

The invention relates to a method for attaching a sheet or a film to an underlayer using an adhesive, the film and undercoat during application and following on, respectively the application of the adhesive to the film and / or to the lower layer can be pressed against one another according to a line which progresses from one edge of the film to the other edge.

There are many forms of attaching a film on an underclass. One of the most well-known forms is the application of a wallpaper on a wall, whereby beforehand

with adhesive provided webs are arranged side by side in the vertical direction. It is also general known foils, which are provided with an advertising print are, as well as with a self-adhesive layer on the other side, which self-adhesive layer with a Silicon paper is covered, for V / erbebeitrag to attach to objects, being done before attaching the foil removed the silicone paper used as the cover layer. Such films are also known for cladding of all kinds of objects to maintain a different color or pattern. It is also known from sheets To provide plastic or paper with a non-active adhesive layer which is activated by heating and then it gets sticky. In industrial applications it is known to put the sub-layer, e.g. a panel, together with the film to be applied through between two rollers, the film being pressed onto the lower layer will.

Apart from this industrial application, all of the above-mentioned applications take place by hand. The application of such foils requires great skill and the difficulties increase depending on the size of the foils and when they are to be attached to non-horizontal surfaces such as the vertical walls of, for example, vehicles. The largest dimension that you could manage by hand until now when applying it to vertical surfaces and with a previous coating of the film with a self-adhesive layer is 1x1 meter. This is used, for example, when attaching advertising labels to vehicles. Attaching the individual sheets to one another without creasing and connecting them to one another then poses a major problem. Furthermore, it is of course known to attach strips of wallpaper with a width of 60 to 80 centimeters in the vertical direction. Due to the small width and the fact that the '

Mass must be attached essentially in a vertical direction, such tracks are still to be handled, also because an adhesive is used which does not immediately adhere, so that it is incorrect Arrangement pulling away and rearranging is possible. The upholsterer will also take care of the fact helped that these sheets were made on paper and by the adhesive diluted with water Become supple and pliable and thereby create small creases when the adhesive and thus the paper web dry be pulled smooth. Similar relationships occur when affjasheh is attached to advertising pillars.

However, when it comes to attaching large foils on difficult surfaces it is almost impossible to do this by hand, especially when using these foils consist of plastic films, which are provided with a self-adhesive layer or on a previously arranged Adhesive layer are to be attached, especially if these adhesive layers have properties of great strength have been, because such self-adhesive adhesive layers or adhesives applied to the underlayer have the ability to immediately and thoroughly grasp every object that comes into contact with it, so that it is extremely difficult to correct mistakes. So far, large slides have not yet succeeded It is absolutely impossible to apply sheets with a horizontal length of several meters to be applied in a quick and flawless manner.

The need arises, however, especially when one imagines large areas of trucks and containers which so far only in paint spraying workshops can be provided with labels, but a processing which takes several days to a few weeks take.

There are also materials such as glass and fiber structures which are to be coated with a film and which are on Due to their low strength, they cannot be treated in the usual rollers.

The purpose of the invention is now to create a method and a device with which it is possible to run webs : Any dimension can be perfectly applied to any surface regardless of its position or profile, and this too is possible on surfaces that are not completely smooth or are flat by using grooves, mete, profile strips and such are provided.

In its generality, this purpose is achieved by immediately preceding the line mentioned and moving with it is practically applied over the entire length of this line under pressure in such a way that the film is pressed onto the lower layer by atmospheric pressure. The fact that the under pressure in in such a manner and place and progressing with the line of attachment. is exercised, one achieves that the atmospheric pressure, where the foil comes into contact with the underlayer, for a always ensures even pressure, which pressure you certainly not with the hand and also not with rollers reach kf.nn, especially not if the lower layer is flexible or uneven. If the lower layer is permeable, so one can apply the "negative pressure on the back side of the backsheet, i.e. on the side which is from facing away from the side on which the film is to be attached. This applies, for example, to the tarpaulin of Vehicles.

If the lower layer is not permeable, which will most often be the case, the negative pressure will be between Foil and underlayer exercised and in particular

6Q9834 / 06S6

according to a narrow strip the length of which is the greatest The width of the slide. You so to speak suck the air out of the area which is immediately in front of the place located where the film comes in contact with the underlayer, leaving the atmospheric pressure on the other Side of the film ensures that the film is pressed correctly.

According to the invention, it is useful for the lower layer and / or to heat the film. This is especially true for foils which expand slightly when heated and after making the connection with the cold underlayer, shrink again a little and thus good be excited. This is even more useful if the film is made of a thermoplastic material because it also becomes pliable due to the heating and then adapts well to uneven areas of the lower layer can and can even follow profiling of this lower layer. Also, the warming can be used for activating a non-active adhesive.

The heating is preferably applied at the point of and / or immediately in front of the said line of locomotion. This heating can take place by means of a stream of hot air or by means of thermal radiation.

The negative pressure can be generated in a simple manner by means of a vacuum cleaner and the heated air by using it of the evacuation of the vacuum cleaner in which a heating element can be arranged.

The invention also relates to a device for using the method described. This device can according to the invention be carried out in this way in its generality be that this device is provided with a gap-shaped suction mouth, with means for guiding this

• ι *

Suction mouth over the lower layer, as well as with means for carrying a supply roll of the film and for guiding the from the supply draining part of the film along the suction mouth, which suction mouth in the position in which it is open the bottom layer adjoins the mouth towards the point where the film on the bottom layer connects. Such a device can be used in any position of the slider, while during of applying the film to the lower layer, this suction mouth can move over the lower layer or the lower layer can move with respect to the suction mouth. This device can be provided with heating means, which can heat the film at a point between the supply and suction mouth, so before the film with the lower layer comes into contact. It deserves the advantage of extending the heating over the area of the film, which is already is applied to the underlayer. The guide means can be of any suitable shape.

If you have to do with a lower layer which is provided with profilings which run in the direction of movement of the attachment of the film, the device is preferably provided with a profiled guide plate which is located between the supply roll and the suction mouth, as in the area of the heating means. You then achieve that the film automatically adapts to the profile. Such a profiled plate can be interchangeable so that a suction mouth, which is provided with a flat guide plate between the supply roll and the suction gap, can easily be changed into a device which is suitable for attaching foils to profiled sub-layers. The nozzle for the heated compressed air is preferably located opposite the guide plate in order to promote the adaptation of the plastic film to the shape of the guide plate. In the case of difficult surfaces such as vertical surfaces, the suction mouth is

- 6 609834/0656

preferably hung on a guide member, which is provided with leg for the attachment of this organ to the object to be treated and by means of which the suction mouth moves according to a predetermined line can be. If you have to do with vehicles, e.g. trucks or containers, the guide frame is preferably there From a car, i.e. a frame with four wheels, drive more gently onto the upper edge of the vehicle can. Such a carriage can be made from simple structural elements adjustable in width and on the width of the upper part of the vehicle can be adjusted.

According to the invention, it is advantageous to provide the carriage with a guide rod which is parallel to the direction of movement of the carriage, which rod is longer than the carriage and on which the suction mouth with the supply roll is suspended displaceably in the longitudinal direction of the rod. Because this rod is longer than the car reaches you can work the entire length of the vehicle with the suction mouth, because it is moved further can be allowed as the wheels on the upper part of the vehicle.

The suction mouth can be articulated around a horizontal axis on the Car to be hung up. However, it is preferred to guide the suction mouth in a displaceable manner on horizontal pins of a frame which can be hung on the guide rod, which pins are directed perpendicular to the plane of movement of the suction mouth are which surface is parallel to the direction of movement of the carriage. The suction mouth is then always the same Distance to the plane on which the film is to be arranged and will even oppose each other during operation suck this area. This automatically adjusts to vertical profiles or uneven areas, which adaptation can still be promoted by the fact that the suction mouth has a flexible mouth.

609-8 ^ 70856

However, it is also possible to adapt to uneven or uneven surfaces. Profile ie nuigen to bring about that the yielding Orifice is used with a suction mouth whose position in relation to the surface to be processed is fixed is like a suction mouth which can pivot around an axis which is parallel to the one to be processed Surface and is directed transversely to the line of locomotion.

According to the invention it is also possible that the guide member consists of a supporting structure which is provided with a guide rod for the suction mouth. This structure can be made from Elements consist of which are attached to the object to be processed as well as of a position which is set up next to the object.

The suction mouth is preferably provided with means for braking the film, e.g. in the form of leaf springs or in the form of a brake on the supply roll, which ensures that the film is kept taut.
