embossing / laminating - One of several ways in which two layers or plies of embossed product are brought together in a laminating nip for a general process known as double-nip embossing laminating. Nested lamination means that the raised elements of each layer fit between each other, as in interdigitating, so that the tops of each element come into contact with the recessed area (or floor) of the opposing layer. Although it is theoretically possible to cause the embossing rollers to engage with each other (as in a nip) with nested embossing, most laminators run with a significant gap between the engraved embossing rollers to prevent any possible interference between the raised elements, just in case the rollers were not installed correctly. In normal practice, an adhesive glue is applied to the tips of the raised elements of only one of the two layers, and those tips are bonded to the floor of the other layer. Other versions of embossing laminating are pin-to-pin, and random registration.
