Document Type and Number:

WIPO Patent Application WO2004110749

Kind Code:

A3

Abstract:

An apparatus and method for producing an elastomeric nonwoven laminate including a plurality of elastic strands joined to a nonwoven web in a controlled distribution is provided. The apparatus includes an extruder for extruding a plurality of elastic strands onto a cooled surface of a rotating drum, which transports the strands in parallel alignment to a nip formed between two rollers rotating about parallel axis. The drum transfers the plurality of strands to the nip in a controlled distribution where it is bonded with the nonwoven.
