23836 ABSTRACT OF THE DISCLOSURE A moist, porous web is consolidated and dried by running it through the nip between two rotatable rolls, the surface of one of which is heated as it approaches the nip. One side of the web is in direct contact with the surface of the heated roll and the other side faces a permeable surface. The rolls are pressed together under high pressure to transfer heat from the heated roll to the web compressed therebetween to dry the same. The roll sur- face may be heated by hot gases from a fuel combustion burner or by a liquid medium. The dried and consolidated web may be removed from the heated roll by doctoring or it may be conveyed from the nip between the rolls to apparatus for processing it further.
