Abstract
To provide a selective and repetitive junction system by adhesion of separate parts an adhesive element is suggested which is capable of being jointed only with another identical or similar element, which comprises a carrier and an adhesive layer on at least one side of the carrier, said layer being composed by an elastomeric material firmly anchored to the carrier. The layer is preferably rather thin and smooth.
Claims4
In a joining system wherein two like elements are to be repeatedly connected together and released, an adhesive element comprising a carrier and an adhesive layer carried by one side of said carrier, said adhesive layer being formed of elastomeric material and being firmly anchored to said carrier, said adhesive layer having a face surface bondable only to a like face surface, and the strengths of said carrier and that of the anchoring of said adhesive layer to said carrier being greater than the releasable bond between like face surfaces, said elastomeric material being cured but only to such a degree that said elastomeric material retains its adhesive characteristics on said face surface, said elastomeric material being cured to a different degree through its thickness with the degree of curing being the stronger adjacent said carrier.
A releasable joining system comprising two separate but like adhesive elements repeatedly joinable and separable relative to one another, each of said adhesive elements comprising a carrier and an adhesive layer carried by one side of said carrier, said adhesive layer being formed of an elastomeric material and being firmly anchored to said carrier, said adhesive layer having a face surface bondable only to a like face surface, and the strengths of said carrier and that of the anchoring of said adhesive layer to said carrier being greater than the releasable bond between like face surfaces, said elastomeric material being cured but only to such a degree that said elastomeric material retains its adhesive characteristics on said face surface, said elastomeric material being cured to a different degree through its thickness with the degree of curing being the stronger adjacent said carrier.
