Abstract
A method of adhering first and second elongate webs includes depositing a first component of a two-component adhesive on a first face of the first elongate web and depositing a second component of the two-component adhesive on a first face of the second elongate web. The first face of the first elongate web and the first face of second elongate web are brought into contact, and the two components are mixed ultrasonically. In an alternate method, a two-component adhesive on at least a first face of the first elongate web, with at least one of the two components micro-encapsulated so that the two components of the two-component adhesive do not react. The first face of the first elongate web and the first face of the second elongate web are brought into contact. Ultrasound and/or heat is applied to free the microencapsulated components of the two-component adhesive, so that the components of the two component adhesive can react.
