Device Having a Renewable Blade Surface For Treating a Target Surface

A device for treating liquid on a target surface, said device comprising:

• a pressure applying member, said pressure applying member having a primary orientation extending in a widthwise direction, said pressure applying member projecting in a longitudinal direction from a proximal end to a distal end suitable for contacting a film against the target surface, said pressure applying member having opposed first and second sides intermediate and connecting said proximal end and said distal end;
• whereby a sheet, if installed in said device, is movable in the longitudinal direction relative to the said pressure applying member, said sheet having a portion thereof movably positionable across the distal end of said pressure applying member from said first side to said second side thereof, to contact said target surface, or liquid deposited thereon, with the portion of said sheet positioned across said distal end of said sheet;
• and
• a sheet advance mechanism to move the sheet across said distal end of said pressure applying member in the longitudinal direction.
