Abstract
A soft contact roll is mounted immediately downstream of the generator roll in a single facer to press the freshly glued single face web against the surface of the heated fluted bonding roll with a light load uniformly distributed across the full width of the web. The contact roll helps spread the adhesive more quickly and uniformly.
