The invention relates to a method for bonding flat moulded parts, according to which an aqueous adhesive dispersion is applied to at least one contact surface of the moulded parts that are to be bonded. Said aqueous adhesive dispersion is then dried carefully with the aid of electromagnetic radiation. Substantial portions of the radiation, which produce heat, lie in the near infra-red wavelength range. Coated (sheet-shaped) moulded parts of this type can be stored temporarily and the adhesive layer can be subsequently activated in such a way that the moulded parts can be optionally joined together by compression. Said method is suitable for producing moulded parts used in vehicle manufacturing, in particular door side sections, roof liners, body columns, rear parcel shelves, dashboards and similar functional elements used in vehicle manufacturing. |
