Abstract

Methods, devices and support profiles are configured to match the method and device in profiles used to attach a support section for rubber seals to automobile body parts in the shortest possible time with the minimum of tools and personnel. The methods and devices are adaptable in such a way that modifications to the geometry of the sealing section and to the contours of the body parts are accommodated without long stoppages of the assembly line. The support sections and connecting regions mold to all the contours of automobile bodyworks, in particular corner regions, and permit the attachment of various sealing regions and application of extreme detachment forces. The support section for the sealing section is attached to the support surface in one single operation. The sub-steps of said operation are carried out by an industrial robot. Adhesive is applied to the support section during its production.

Claims

1. Method for positioning support sections (1) for rubber seals (11) on support surfaces (4), such as, for example, door bodies and trunk seals of automobiles using an application apparatus (3) in the form of an industrial robot which follows the contour of the support surface (4), whereby the support section (1) is pulled out of a drum-like storage device (2) by the application apparatus (3), guided by the application apparatus using guide rollers (5) after leaving the storage device (2), cut after attaining its final length by a path-controlled cutting unit (6) in the application apparatus (3) and pressed by the application apparatus (3) upon the support surface (4) using pressing and guide rollers (8), wherein the support section (1) is brought into adhering connection to the support surface (4) by the application device (3).

2. Method according to claim 1, wherein the application apparatus (3) applies the adhesive system to the support surface (4) using a coat of adhesive (7).

5. Method according to claim 1, wherein the application apparatus (3) sets the adhesive action of the adhesive system (12) into motion on the self-adherent support section (9) using an activation unit (10).

3. Device for positioning support sections (1) for rubber seals (11) on support surfaces (4), such as, for example, door bodies and trunk seals of automobiles, consisting of a storage unit (2) on which the support section (1) is rolled up, of an application apparatus (3) which includes at least 2 guide rollers (5), a path-controlled cutting unit (6) as well as at least one pressing and guide roller (8), wherein the application apparatus (3) is constructed with a coat of adhesive (7).

4. Self-adherent support section (9) for sealing sections (11) on support surfaces (4), such as, for example, door bodies and trunk seals of automobiles, wherein a gutter-like groove is hollowed out on the side which is to be joined with the support surface into which an adhesive system (12) is applied already during the manufacture of the self-adherent support section whose adhesive action is nonetheless first set into motion upon positioning the self-adherent support section on the support surface.

6. Device for applying self-adherent support sections (9) for rubber seals (11) on support surfaces (4), such as, for example, door bodies and trunk seals of automobiles, consisting of a storage device (2) on which the self-adherent support section (9) is rolled up, and of an application apparatus (3) which includes at least 2 guide rollers (5), a path-controlled cutting unit (6) as well as at least one pressing and guide roller (8), wherein the application apparatus (3) is constructed with an activation unit (10).

7. Support section (1) and connection region (13) for fastening sealing sections (11) to support surfaces (4) of automobile bodies, wherein the support section (1) is constructed in the form of a long, straight line segment (15) which is positioned on the support surface (4) using an adhesive system (12) and which runs somewhat parallel to the support surface (4) of the automobile body in the region of the adhesive surface, wherein the support section (1) has a retention peg (16) which points in the direction of the sealing section (11) and ends in a trapezoidal slip-fit flange (17), wherein the connection region (13) is constructed C-shaped and embraces the trapezoidal slip-fit flange (17) form-locking, wherein the connection region (13) is connected with the sealing region (140 of the sealing section (11).

8. Support section (1) according to claim 8, wherein the end of the segment (15) which lies opposite the retention peg (16) is constructed as a lip (18) which points toward the support surface (4) of the automobile body.

9. Support section (1) according to claim 8, wherein the surface of the segment (15) pointing toward the support surface (4) of the automobile body has an adhesive system (12) which was already applies at the manufacturer.
