Provided is a method for bonding continuous traveling webs, which allows for significant increase in web processing speeds. A method according to the present invention includes providing a web including a bonding agent that may require activation prior to adhesion. Bonding agent activation may be, for example, by heat transfer or wetting. The primary activation of the bonding agent occurs separately from any applied force required for proper adhesion. Adhesion force may be applied by a noncatalytic pressure means including a crimp roller. The method may further include the insertion of a product between web layers to be brought into adhesive engagement with one another. A further web process step may include the cutting of bonded webs.
