Abstract: Methods and apparatuses for roll coating are provided. The roll coating system (100) includes a coating roll (110) having a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14), the inner layer being softer than the outer layer. A substrate (3) is conveyed to the nip (12) between the coating roll and a back-up roll (120). A metered coating material is transferred from the coating roll to a patterned surface structure (40) of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.

Abstract: Methods and apparatuses for applying coatings (9) on a moving web (3) are provided. A slot die (20) and a back-up roll (11) engage with each other. The back-up roll has a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14). The slot die and the flexible web at a contacting area are impressed into the back-up roll with an engagement depth D, which enables formation of a coating having a substantially uniform thickness.

Abstract: An idler roller having a fixed shaft with at least one spherical bearing and a second bearing which may, but need not be, a spherical bearing. In some embodiments, the second bearing is slidably-mounted on a central shaft. A shell is mounted between these bearings. Any changes in dimensions resulting from changes in temperature may them be accommodated by sliding movement of the second bearing, sparing the shell from distortion by bending or buckling. In other exemplary embodiments, the spherical bearing includes a first housing element fixedly-mounted on a central shaft and a complementary first free element disposed against the first housing element. A second bearing element is mounted on the central shaft, and a shell is attached to the first free element and rotatably-mounted to a second bearing element with a biasing element mounted on the central shaft urging a second free element away from the first free element.
