Methods and devices for bonding a plurality of substrates in a nip provided between an anvil and a bonding device may involve preheating a portion of a first substrate for a preheating duration to impart a preheated temperature, and then conveying the plurality of substrates to the nip to form a bond. The portion of the first substrate may reach the nip at a final temperature that is within 0° C. to 40° C. of the preheated temperature. A time-in-nip to create the bond may be less than 20 milliseconds. The preheating duration may be at least 200% longer than the time-in-nip. Laminate materials formed via such methods and devices may include unbonded areas in the nonwoven material that may have at least 5 fibers per square inch that are fused at fiber-to-fiber intersections caused by preheating the nonwoven material.
