  • Publication number: 20260047645
    Abstract: A connection system has a first adhesive which has a plurality of adhesive elements. The first adhesive has a first free end and a connection region, wherein the connection region is arranged or formed on a carrier element preferably designed as a flexible tape. A first pivotable part of the first adhesive is movable, in particular, pivotable, relative to the carrier element. The first pivotable part has free edges. In a state in which the first pivotable part is not pivoted relative to the connection region, i.e., in which both lie in a common plane, the free edges in the plane are not directly surrounded by adhesive elements of the first adhesive. The first pivotable part has, in particular, a larger number of adhesive elements than the connection region. A method for releasing such a connection system is disclosed, wherein the connection system has a second adhesive.

  • Patent number: 12534644
    Abstract: The present invention relates to a carrier for adhesive, with the carrier being configured to be attached to a surface having a topology, in particular a time variable topology, such as a part of a human or animal body. The invention further relates to a use of the carrier, to a method of activating a carrier and to a method of making a carrier.

  • Publication number: 20260016325
    Abstract: A method for the state detection of a connection system includes a first adhesive means, a second adhesive means and a sensor arrangement. The method determines a position of the adhesive means relative to each other, wherein the first adhesive means is brought close to and/or attached to the second adhesive means and at least one parameter relating to the positioning is detected by the sensor arrangement. After alignment of the adhesive means, a final attachment can be carried out. The method can equally be used to detect the adhesion of the first adhesive means to the second adhesive means and/or to determine the loading or non-loading of an adhesive connection. Processed and/or unprocessed sensor data can be sent wirelessly by means of a communication component. A connection system is designed to carry out the aforementioned method and to a set including the connection system and a mobile router.

  • Publication number: 20250382502
    Abstract: An adhesive tape has a carrier and first and second projections, each of which is directly connected via one end to the carrier. The projections are situated on opposite carrier surfaces on the surface of the carrier. A first surface density with which the first projections are distributed on the first carrier surface is different from a second surface density with which the second projections are distributed on the second carrier surface. A further layer can be provided between layers of the carrier in order to be able to make the layers thinner while still maintaining high stability.

  • Publication number: 20250326185
    Abstract: A method for attaching a fastening system is disclosed. The fastening system has an application agent which, when viewed in relation to a surface to which it is applied, forms a smooth adhesion surface, in particular, after curing, and a functional part which, on its side facing the adhesion surface, has a functional surface which can be secured to the adhesion surface in a releasable manner. The method includes applying an agent onto the surface, allowing the application agent to cure so as to form a smooth adhesion surface, and attaching the functional part via microstructures of one functional surface to the adhesion surface of the cured application agent.

  • Publication number: 20250204648
    Abstract: A method for producing a touch-and-close fastener part has a plurality of adhesive elements with front-side contact surfaces for releasable adhesion to other components by an adhesive force. The adhesive elements are formed from a coating material in mold cavities of a mold screen of a molding tool. In the method, a carrier web is fed to the coating material and the adhesive elements are formed in the mold cavities of the molding tool on a side of the carrier web facing the coating material. The carrier web is preferably connected to the coating material before the adhesive elements are formed. A device for producing the touch-and-close fastener part is disclosed.

  • Publication number: 20240298754
    Abstract: A connection system consists at least of an adhesion part and a fastening part. The adhesion part has at least one support part having a plurality of stem-like adhesion elements integrally joined thereto, the head parts of which adhesion elements can be releasably fixed at their free end faces to third components by means of adhesion. The fastening part is rigidly connected to the adhesion part on one side, and on another, opposite side has exposed fastening elements which, when brought into engagement with additional, correspondingly designed fastening elements of an additional fastening part, form a releasable adhesive fastener.
