Abstract: A process for embossing a twin-web of film is described wherein a length of two superimposed webs of film are heated to a temperature above the vicat softening point, then passing the webs between a pair of embossing rolls at least one of which has an engraved surface which is sufficiently cooled to cool the webs to a temperature below the vicat softening point. The embossed webs are then passed into the nip of a pair of counter rotating driven rolls each having a high friction surface, separating the webs downstream of the nip by each of the webs maintaining contact with the surface of its respective driven roll, releasing each of the webs from its respective driven roll by continuing its passage over a co-operating pick-up or nip roll and then drawing each of the webs to separate wind-up stations.
