Definitions
- the present invention relates to a method for producing a sealed by an adhesive rabbet joint between a first surface element which comes to rest in the fold, and a second surface element which comes to rest in the fold, wherein a flange of the first surface element via a flange of second surface element is repelled and wherein the flange of the first surface element has a first surface and a second surface, comprising the steps:
- a rabbet joint between two panels is created by repelling an extended edge portion of one panel over an edge portion of the other panel.
- the result of the folding is referred to as seaming or flanging seam or flanged edge, the connection as a seam or flanged edge connection.
- a vehicle door may be made of an inner panel and an outer panel connected along their outer edges by a rabbet joint made by folding the extended edge portion of the outer panel over the edge portion of the inner panel to create an overlapping joint and crimping the edges together.
- a seal is then needed between the edge of the outer panel and the adjacent surface of the inner panel to keep moisture out of the space between the panels and prevent corrosion. If the seam or crimp edge connection is sealed, this is called a crimp seam seal or, in the case of the use of adhesive, also a crimp edge bond.
- the bonding or sealing of sheet metal parts in vehicle construction, especially in the bodies of automobiles, is often made on sheet metal parts.
- the curing of the adhesives / sealants used in this case takes place later in the paint drying ovens. Previously, the bonded or sealed parts undergo cleaning, phosphating and dipping priming steps. By means of the treatment agents used in these stages, the adhesives or sealants can be rinsed out of the adhesive joints.
- a curable material is placed in particular in the form of a bead over the outwardly open region of the fold, which gelled in a first curing process, such as inductive heating of the sheet in the curable composition, and in a subsequent curing process, in particular the KTL oven is fully cured.
- the hardenable mass used here is PVC in particular.
- two sheet metal parts are connected by means of folding.
- the body shell first an adhesive on the oily metal sheet, usually consisting of steel, galvanized or galvanized steel, magnesium or aluminum, along the edge of the outer part, for example by means of extrusion, spraying or spraying in a layer thickness of, for example 0.2 mm applied, and after inserting the inner part, the outer edge of the outer part is crimped around the periphery of the inner part.
- the corrosion-prone edge of the outer part is then only in the painting process usually by hand with a sealant, such as PVC plastisols, sealed.
- WO 201 1/020714 A1 discloses a rubber-based adhesive composition which can be used simultaneously as a bead seam sealant. It is a pasty composition that can be applied by spraying, extrusion or spraying. This is also the disadvantage of this mass, as easily order errors and squeezing can occur, which affect the visual appearance of the flanged seam.
- EP 1 041 130 A2 VW-Sika
- EP 1 334 161 B1 L + L Products Inc. discloses a process for preparing and enhancing a compound comprising the following steps:
- US 4,719,689 A discloses a method for simultaneously bonding and sealing a hemming seam in which the hemming tool is provided with a recess by means of which the adhesive emerging from the hemming seam is formed into a visually appealing sealing layer.
- the disadvantage is that with an inaccurately metered or placed amount of adhesive the Underfill or overfilled, which may affect the sealing function and appearance.
- US 6,000,118A discloses a preformed adhesive patch strip which is crimped during beading. This involves - as with adhesive beads - the risk of squeezing.
- EP 0 830 530 B2 discloses a weather strip suitable for sealing a joint between two surfaces adjacent to one another generally in parallel planes, for example surfaces (like plates) abutting or overlapping one another.
- the invention is particularly, but not exclusively, applicable to a weather strip suitable for sealing a seam joint as found in a vehicle body.
- the sealing strip has an inner surface for fastening the strip over the connection and a rounded, shape-containing outer surface; wherein the profile of the strip is such that when the strip is secured in position over the joint, the outer surface of the strip extends from one of the adjacent surfaces to the other.
- a disadvantage of this solution are the elaborate preforming of the outer surface of the strip and the necessary multi-layered structure.
- EP 1 451 010 B1 (3M) and WO 2004/108401 A2 likewise disclose a flange profile sealing material having at least two layers for sealing a flange profile of sheets in a vehicle, wherein the flange profile sealing material is characterized in that an inner layer containing a hot melt / flowing thermosetting resin having a curing temperature of 80 to 200 ° C, and an outer layer showing no substantial flow / shape change at 80 to 200 ° C, wherein the heat-melting / flowing thermosetting resin be liquefied and then cured to form a seal.
- the sealing material is externally molded around completely around the already made flange. It thus only performs a sealing function and no essential mechanical connection function (bonding).
- WO2012 / 166257 A1 discloses a method for producing a seaming connection, in which an adhesive tape is first applied to the inner or outer metal sheet of the seaming connection, then the outer sheet is wrapped around the inner sheet metal, so that the adhesive tape completely between outer and inner metal sheet of the rabbet joint comes to rest, and then the tape is cured. With this method, a Bördelnahtverklebung is produced. The disadvantage is that during the bonding, the edge of the outer folded sheet remains unprotected and must be sealed in a further operation.
- WO 2009/071269 A1 discloses the application of two adhesive tapes (FIG. 2) to one of the flange plates. During the subsequent crimping, the adhesive tape is squeezed out of the flare joint and forms a seal both to the inner and to the outer side of the fold. Despite the use of an adhesive tape, as in the case of the liquid adhesive, a significant flow process takes place, which causes the above-mentioned. Disadvantages. It was therefore an object of the present invention to provide a method for the simultaneous gluing and sealing of a seam connection, which can be carried out with little effort and results in a visually improved sealing seam compared to the prior art.
- the object is achieved by a method of the type mentioned, in which the adhesive is applied to both surfaces of the flange of the first surface element, and after the production of the seaming compound, the adhesive on the first surface with the adhesive on the second surface of the flange of the first Surface element forms a continuous layer on the edge of the flange, which covers the edge of the flange of the first surface element.
- the flange of the sheet lying outside is provided on both surfaces with a layer of a sealant and / or adhesive before the seaming is produced, wherein the projection of the layer on the first side into the plane of the layer on the second side lies at least partially within the layer on the second side, and after the production of the seaming the Klebemasse Mrs on the first surface of the flange with that on the second Surface connected.

- the outside in the Falzitati coming flange is hereinafter referred to as the outer flange, the inside to come to lie as an inner flange.
- the second flange can rest with its end section in a region on the first side of the first flange, on which adhesive is applied, so that there is a region in which the adhesive is arranged between the two flanges (see FIG.
- the second flange is spaced from the adhesive region of the flange directly on the first side of the first flange (see Fig. 2.2). In this case, even if the distance from the second flange to the adhesive is only slight, when beading initially a cavity not filled with adhesive.
- the adhesive layer applied to both sides of the outer flange may be the same or different.
- the adhesive layers can each be present individually before the seaming connection is produced or already be formed coherently. In the case of individual adhesive layers, they may consist of the same adhesive or of different adhesives. Even with an already coherent adhesive layer, it is possible that two different adhesives are already connected, ie connected to one another. When the adhesive layers are single, they are joined to form a continuous layer as the seaming is made. A coherent adhesive layer is preferred. Therefore, it is particularly preferred if the application of the layer of the adhesive in step A takes place as a continuous layer which covers the first surface, the second surface and the edge of the flange.
- the adhesive is an activatable adhesive, wherein the adhesive is activated in a further step (C) after the flanging in step (B) for producing the hem flange.
- the adhesive is cured.
- the adhesive is preferably initially flowable. It flows on the Flanges on, so that a high-quality bonding and sealing is made. As a result of the flow, even in the event that the adhesive layers were not connected before the seaming was produced, a coherent adhesive layer is now obtained which ensures complete sealing of the seaming connection.
- a layer of adhesive is thus applied to the first surface and a further layer of adhesive is applied to the second surface of the outer flange, wherein the two layers are connected during the production of the seaming connection by activation of the adhesive to form a continuous layer.

- the adhesive tape may be partially or completely provided with a carrier material.
- the carrier material comprises all flat structures, for example films or film sections which are expanded in two dimensions, tapes of extended length and limited width, strip sections, diecuts, multilayer arrangements and the like. Different carriers such as films, fabrics, nonwovens and papers can be combined with different adhesives for different applications.

- the carrier material has a softening temperature which is below the activation temperature of the adhesive.
- the support material softens upon activation of the adhesive, can flow and thus compensate for stress due to shrinkage or expansion.
- a single adhesive tape is applied around the edge of the flange.
- this adhesive tape is a double-sided adhesive tape, then this is usually covered on at least one side with a liner.
- Pressure-sensitive adhesive tapes which are coated with adhesives on one or both sides, are usually wound or crosswound at the end of the production process into a roll in the form of an Archimedean spiral.
- the adhesive tapes before wrapping with a cover material also referred to as a release material
- cover material also referred to as a release material
- a liner is not part of an adhesive tape, but only an aid for its production, storage or for further processing. Similarly, the composite is only temporary and not permanent.
- a prior art liner consists of at least one abhesive layer (release layer) to reduce the adhesion tendency of adherend products to these surfaces (release function). This layer can be applied to a carrier material.
- any of the systems known to the person skilled in the art in particular those which are mentioned in the Handbook of Pressure Sensitive Adhesive Technology by Donatas Satas (Satas & Associates, Warwick 1999), can be used as a separating layer

- Polymer-coated papers or nonwovens are also to be found.
- This liner is at least removed from the adhesive tape or part of the adhesive tape located on the first surface of the outer flange before the beading is carried out.
- the liner is removed only on the adhesive tape located on the first surface of the outer flange or part of the adhesive tape so that no adhesion to the crimping tool occurs during crimping. This is in the execution as a glued single tape facilitated by a two-piece or perforated liner in the longitudinal direction of the adhesive tape, from which then only a part is removed before flanging.
- the adhesive tape is an adhesive tape composed of two adhesive composition strips arranged parallel to one another and composed of different adhesives. These strips are arranged on a single liner so close together that they are connected together or in the course of the process, a connection is made.
- the second adhesive located on the second surface of the outer flange has, after an optional activation step, a lower modulus of elasticity than the first adhesive present on the first surface. This prevents the occurrence of cracks in the surface of the second adhesive by, for example, thermal expansion or shrinkage during further process steps, which is exposed to the flange, and thus leads to a visually better appearance.
- the adhesive tape glued around the edge of the flange is a partially single-sided adhesive tape.
- the carrier material is applied in the longitudinal direction only on the part of the width of the adhesive tape, which comes to rest on the second side of the outer flange.

- the carrier or liner material is preferably a thermoplastic polymer whose softening temperature is below the activation temperature of the adhesive. This has the advantage that the material flows during activation of the adhesive and thus can compensate for stress due to shrinkage or expansion. Furthermore, it is preferred that the adhesive of the second adhesive tape, which is covered by the carrier material, after activation has a lower modulus of elasticity than the adhesive of the first adhesive tape.
- Adhesive compositions, hot-melt adhesives or activatable adhesives can be used as the adhesive.
- an activatable pressure-sensitive adhesive has the advantage that even before activation, an adhesive composite of the fabric is produced. By activating the strength of the adhesive bond is then increased.

- a carrier material (32) covers a second adhesive composition strip (34) from a second adhesive.
- the adhesives of the adhesive tape strips (33, 34) are different.
- the adhesive masking strips may be in contact with each other as shown, or spaced apart. If they are spaced, it is advantageous for the liner (31) to cover both adhesive tape strips to make the composite more stable.
- the carrier material is arranged in the longitudinal direction only on a part of the width of the adhesive tape. In the case of different adhesives, it can at least partially cover one or even several adhesives.
- the carrier material is arranged on the edge of the adhesive tape, as shown in FIG.
- the adhesive masses of the adhesive tape strips (33, 34) are identical and the strips are in contact with each other.
- the carrier material is equipped with a release agent and the liner running on both sides, so that the adhesive tape can be advantageously wound without using a further liner on a roll.
- the liner not only covers the first adhesive patch strip but also the backing material. This protects the substrate and makes it easier to remove the liner due to lack of adhesion to the substrate. If the liner in this version is designed to cut on both sides, the adhesive tape can be wound up into the roll without another liner.
