METHOD AND APPARATUS FOR STEAM LAMINATION

摘要

Two sheets of material (42 and 43) 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 (lines 21, holes 17) (preferably superheated) through one sheet of material (43) into the adhesive layer; c) compressing the heated composite (between rollers 13 and 39) 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 (10 and 11) past narrow jets of the steam.
