Abstract:
An apparatus for making a flexible sheet product for sorbing liquids, said apparatus comprising:a frame; a first drum assembly including a first, generally cylindrical screen, the first drum assembly mounted to the frame for rotational movement in a first rotational direction; a first vacuum within the first drum assembly for pulling air in a first direction into the first drum assembly; a second drum assembly including a second, generally cylindrical screen, the second drum assembly mounted to the frame for rotational movement in a second rotational direction opposite the first rotational direction; and a second vacuum within the second drum assembly for pulling air in a second direction, substantially opposite the first direction, into the second drum assembly, the first and second vacuums creating a loft zone between the first and second drum assemblies such that a molten polymer-based material blown into the loft zone is pulled in substantially opposite directions onto the first and second screens of the first and second drum assemblies, respectively, forming a flexible sheet product for sorbing liquids.
