  • Method and apparatus for producing laminated articles
    Patent number: 6969441
    Abstract: In the invention, a method is provided for producing a composite nonwoven fabric. A polymer is extruded into heated continuous filaments, possibly elastic, from the die head to a first chilled roller, wherein the extruder is configured to provide the continuous filaments to the chilled roller in a canted direction that is at a tangent or angle to the surface of the first chilled roller. The filaments are conveyed in a downward direction by way of chilled rollers to a nip. In a next step, the nonwoven web is sprayed with an adhesive and is laminated on the continuous filaments in the nip to form a composite nonwoven fabric. The continuous filaments move vertically downward approximately in line with the lamination process, facilitating automatic re-threading of filaments when they are broken or interrupted in their travel downward onto the chilled rolls.

  • Elastic stranded laminate with adhesive bonds and method of manufacture
    Publication number: 20020119722
    Abstract: A laminated article having elastic strands or filaments contained therein for providing elasticity to the article, are provided. The particular adhesive pattern bonds the relatively inelastic nonwoven layers to the more elastic continuous filaments in a pattern that allows adhesive-to-adhesive, adhesive-to-nonwoven layer, and adhesive-to-elastic filament bonding.
