nip or shoe - The part of the laminating process where the layers to be bonded are pressed together to make the adhesive form a better bond. The best way to do this is to apply pressure only at the glue-bond points, and avoid crushing any other part of the product. In nested lamination, this is done by using a marrying roll that is pressed against the same embossing roller that carried the paper which received the glue from the adhesive applicator. In pin-to-pin lamination, this is done in the laminating nip, which is where the two embossing rollers come into contact with each other. With random registration, it is not possible to avoid crushing unbonded areas of the product.
