APPARATUS AND METHODS FOR SECURING ELASTIC TO A CARRIER WEB

摘要

Apparatus and methods are provided to allow for creation an elastic laminate. Non-stretched elastic can be laid at peaks over a nonwoven layer contained in valleys and atop peaks. Stretched elastic can be laid over tented nonwoven to create nonwoven tunnels when a second nonwoven is laid atop the first nonwoven and elastic, and the tunnels resist un-stretching of stretched elastic strands by frictional or obstruction forces. A laminated material comprising a first and second layer of material bonded at spaced apart bond sites is disclosed, with a plurality of elastic strands disposed in a non-linear manner between said first and second layer of material, so that said strands meander in a cross-machine direction and traverse a machine direction line, restraining movement of the strands by frictional forces between the strands and the non-woven layers.

1. A laminated material comprising:
a first layer of material; a second layer of material; a plurality of elastic strands disposed between said first and second layer of material; said first and second layer of material bonded together at spaced apart bond points; said elastic strands laid disposed between said first and second layer of material in a non-linear manner, said strands meandering in a cross-machine direction and traversing a machine direction line, said elastic strands restrained from movement in at least one of said cross-machine direction and said machine direction by said first and second layers.
