Title: Bonding of gripper strip
IPC: C09J7/35
Filed: 1974-03-26
Abstract: 1505651 Carpets EVODE Ltd 26 March 1975 [26 March 1974] 13420/74 Heading A4S [Also in Division B5] A gripper strip is adhesively bonded to a surface in order to facilitate subsequent attachment of a sheet material to the surface, using an assembly comprising an electrically conductive substrate and a layer of heat-activatable adhesive disposed on each face'of the substrate or a single layer of heat-activatable adhesive disposed on one face of the substrate, while the other face is accessible to the adhesive through perforations in the substrate, by positioning the assembly between the gripper strip and the surface and activating the adhesive by electrical heating. The conductive substrate may be an aluminium foil, metal mesh or carbon fibres. If aluminium foil is employed, the foil may be coated on one or both sides as a continuous coating or a discontinuous coating in a desired pattern, e.g. beads or buttons. If the coating is on one face only, the substrate is  preferably perforated. However, an imperforate foil having an adhesive coating on one face only may be used with a separate film of heat activatable adhesive inserted between the uncoated side of the foil and the surface or gripper strip. Alternatively, the separate film may be pre-bonded to the gripper strip. In a further embodiment, the electrically conductive substrate is entirely uncoated and separate adhesive films are applied between the substrate and the surface and the substrate and the gripper strip.  A hot-melt adhesive coated tape as described in Specification 1328347 may be used. Alternatively, the heat-activatable adhesive may be thermosetting, e.g. heat-curing epoxides, phenol-formaldehyde resins, including resols and novalacs, melamine resins, aldehyde resins such as butyrals, thermosetting polyamides, polyimides and polymers and copolymers of vinyl monomers having unsaturated centres capable of cross-linking. A tackifier may be included in the adhesive formulation. The invention is applicable to bonding carpet gripper strips to a floor surface which is first primed using a solution, emulsion or dispersion based on a polymer having an affinity for the adhesive of the assembly. Alternatively, roof covering materials may be fixed to a roof.
