Abstract
A method of gluing pieces of substrate together, by using an expandable gluing system comprising a resin component and a hardener component, wherein the hardener component is acidic, and the resin component comprises one or more gas generating substances capable of forming a gas when contacted with the hardener component, whereby the resin and the hardener components are separately applied onto the substrate. The invention also relates to a device suitable for carrying out the method.
Claims15
A method of gluing, comprising the steps of applying a resin component including a gas generating substance to a first substrate, separately applying an acidic hardener component to said first substrate, thereafter pressing a second substrate onto said first substrate and thereby effecting sufficient mixing of said resin and hardener components to form a glue mixture capable of forming a bond, generating a gas via said gas generating substance and thereby expanding said glue mixture, and forming a glue bond between said substrates via said glue mixture, wherein said resin and hardener components are applied to said first substrate in the form of strands, and wherein an excess, if any, of at least one of the resin or hardener is capable of being used in a respective said applying step.
