Abstract:
1. A method for producing an elastomeric nonwoven laminate comprising the steps of: a) providing a surface cooled drum rotating about an axis and having a surface speed V b) providing an extruder extruding a plurality elastomeric strands in parallel alignment onto the cooled surface of the drum; c) providing first and second rollers rotating about parallel axis and forming a nip therebetween, wherein the first and second rollers have a surface speed V d) providing a first nonwoven with a first bonding surface; e) conveying the first nonwoven to the second roller; f) conveying the plurality of elastic strands on the cooled surface of the drum to the first roller at the first surface speed V g) passing the plurality elastic strands and the first nonwoven through the nip, joining the plurality of elastic strands to the first bonding surface of the first nonwoven in a controlled distribution; and h) conveying the first bonding surface of the first nonwoven over a portion of the cooled surface of the drum enabling the first bonding surface to pick up elastic strands from the cooled surface of the drum that fail to transfer to the first bonding surface of the first nonwoven.
