Abstract
A method for producing a composite web includes supplying two or more webs to an activation mechanism, where the webs are in an unbonded state relative to each other. The method further entails simultaneously activating the webs while they are in a face to face relationship and in an unbonded state, and then bonding the webs to form a composite web.

A method for producing a composite web comprising:
- (i) supplying two or more webs together in face to face relationships into a means for stretching the webs, where the webs are in an unbonded state relative to each other;
- (ii) stretching the two or more webs together until breakage of inter fiber bonds occur while the webs are in face to face relationship and in an unbonded state to induce softness to produce activated and non bonded webs;
- and
- (iii) bonding the activated and non bonded webs together in a face to face relationship with a bonding means to form a composite web.
