Patent ID: 8479371

Claim:
A process for supporting a porous media during a treatment which exposes the media to a fluid that modifies at least one property of the media via flow (F) of the fluid through the media, the process including: providing a perforate supporting core extending along an axis; wrapping the media in a plurality of layers about the core to form a first roll of the media; applying first securement mechanisms that do not extend the axial length of the first roll, subsequent to wrapping to form the first roll, at each end of the first roll for exerting diametrical pressure on the ends of the first roll to prevent fluid flow axially out of the ends of the first roll, while allowing flow of fluid in a direction outward from the core, outward through the media of the first roll and outward past the first securement means; wrapping, subsequent to applying the first securement mechanisms, an additional amount of the media in a plurality of layers about the first roll to form a second roll of the media, which overlays the first securement mechanisms; and applying second securement mechanisms that do not extend the axial length of the second roll, subsequent to wrapping to form the second roll, at each end of wrapped layers of the second roll for exerting diametrical pressure on the ends of the second roll to prevent fluid flow axially out of the ends of the second roll, while allowing flow of fluid in the direction outward from the core, outward through the media of the second roll and outward past the second securement means.
