Abstract

The current solution provides an application tool for stretching an adhesive tape into the correct form and applying it onto a surface. The current solution provides also a tool that helps reducing trim waste and that helps to wrinkle-free and uniformly apply the tape onto a curved part, e. g. a composite part or a metal part.

In some instances tapes, e. g. structural adhesive tapes need to be applied onto curved surfaces, e. g. a curved automotive metal part.

It is known to use pastures adhesives, e.g. structural adhesives, to adhere and seal two metal parts to each other. But these kinds of adhesives may have the disadvantage that they are expanding or oozing through holes in the metal parts. Manually cleaning of these holes can help but takes too long in a production process.

It has been found that an adhesive in tape form can prevent some of the disadvantages of pastures adhesives. This is for example because of its different geometry compared to a pastures adhesive.

An idea to apply a tape onto a curved surface is to use a roller and apply the tape with a roller onto the curved surface. Since the tape needs to be stretched on one side in order to perfectly fit onto a curved surface, an initial tack is required from the tape. If the tape does not provide enough initial tack, the roller solution does not work satisfyingly enough.

Another alternative is to use die cut parts. But the production of die cuts may be too expensive for the according application.

The current solution provides an application tool for stretching an adhesive tape into the correct form and applying it onto a surface. The current solution provides also a tool that helps reducing trim waste and that helps to wrinkle-free and uniformly apply the tape onto a curved part, e. g. a composite part or a metal part.

The tool can for example be an u-shaped profile providing slitted side panels, like for example a cable canal (see below picture).

The tool can also be any kind of profile that can be bend into one direction, e.g. by providing slits. The profile does not necessarily have to be u-shaped. According to the current idea, the tape to be applied is first applie...
