摘要: Two sheets of material are laminated together using a heat-activatable or moisture-curing adhesive by:(a) forming a layered composite of the material with a layer of the adhesive in between;(b) passing steam (preferably superheated) through one sheet of material into the adhesive layer;(c) compressing the heated composite before the adhesive sets;(d) releasing the pressure on the composite; and(e) allowing the adhesive to fully cure.A laminating machine is disclosed that pulls the composite between two open weave belts, past narrow jets of the steam.
