Description

Apparatus for applying a strip-shaped

Dichtimgstnaterials

The invention relates to a device for applying a strip-shaped sealing material to a

Surface,

At various steps in the work, it is e.g. in the

Automotive sector required, a gasket material

In the field of repair and maintenance work of girders, strip-like sealing material is used, among other things, in the assembly of windshields and in the sealing of bodywork! ^" ai zen, but also used in many other operations

Application of strip-type Dichtanqsmaterial currently takes place mainly in that a sealant, e.g. is squeezed out of a cartridge with the aid of a cartridge press, wherein the application via a nozzle with a respective E Eissen appropriate

Outlet cross section is done so that a

Gasket with the corresponding cross section is formed. Alternatively, a prefabricated

Seal strip, for example, in rolled up. Status

is held in stock, be placed on the surface after the surface along a

strip-shaped area was provided with an adhesive. The application of the adhesive can take place with the help of a cartridge press.

Due to the relatively high demands on the

Accuracy and durability of the applied

Sealing strip, it is necessary that the appropriate professionals work with high accuracy, because it is not readily possible, an already attached sealer; to remove again and thus to correct the position of the seal. When applying the sealing strip from a cartridge consists of

Difficulty in applying the sealing material at a constant speed and in a constant width. Although there are Kar tuschenpressen known in which the sealing material is applied by means of a motor-driven Presskoibens, whereby the application of constant volume! However, in this case an unevenness can arise because the cartridge press is not pulled along the strip-shaped application area at a uniform speed. This may result in areas of the weather strip of varying thickness. Furthermore, the application of the

Diehtunqsstreifens along a curved spell with

Difficulties connected, because this requires an exact leadership of the cartridge press. In practice, therefore, it often happens that the sealing strip is placed in a too wide or too narrow radius. To correct such errors, the sealing material must be removed again consuming. Failure to correct the error will result in poor performance, resulting in both technical defects and visual damage

insufficient result.

The same problems exist in the fen fenförmigen

Applying an adhesive on which a prefabricated sealing strip is subsequently applied, it is disadvantageous in the case of the last-mentioned application process that at least two working steps are required in order to obtain a seal to attach a strip of thief, namely the

Adhesive application in a first step and the application of the sealing strip in a second step,

It is therefore an object of the invention to provide a device.- with which the above-described

Facilitated operations and M t softer an exact positioning of the weather strip at a constant application thickness is made possible.

To solve this .Aufgabe the invention provides a

Apparatus for applying a strip-shaped

A sealing material on a surface, comprising a feeding device for feeding the strip-shaped

Diehtungsreateri.als za A Aafbringungsbereich, an outlet opening having Austrittskanana 1 for adhesive and a Ausprssseiement for squeezing adhesive on the Austrittskanai, the outlet opening in the

Aufbrrngungsbereich is arranged so that the adhesive between the surface and the strip-shaped

Sealing material is applied. The device therefore has, on the one hand, a device for applying the adhesive and additionally a device for applying the sealing material, so that at the same time the

Glue on the surface and seal on the surface

Adhesive can be applied. Sticking a

Seal can be done in a single operation.

Another advantage of the inventive device is that the sealing strip relative to

Adhesive is optimally arranged. In addition, the possibility is created by the invention, the amount of T / AT2016 / 000096

4 stripe-shaped reinforcement material and the Kiebs offmenge to match and keep each constant, that an optimal result is achieved.

The mutual arrangement of the feeding device for the sealing strip and the outlet opening for the

Adhesive can either be provided so that the

upset, and will. the sealing strip is then applied directly to the applied adhesive or so that the adhesive first on the

Surface facing side of the weather strip

Applied, and the rait adhesive provided

Sealing strip immediately afterwards can be applied to the surface.

The supply of the strip-shaped Diehtungsrna erials Can be done in various ways, in particular

Seal material is kinked, resulting in undesirable Damage to the seal can result. Furthermore

facilitates the unrolling of the prefabricated

The tread strip feeding and applying the same at a constant speed, the feeder and

Application of the pre-saturated sealant

further facilitates the user to adjust the device in one of the application speed
