  • Publication number: 20240050973
    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.

  • Patent number: 11865571
    Abstract: Methods and apparatuses for applying coatings on a moving web are provided. A coating die and a back-up roll engage with each other. The back-up roll includes a shell rotatably supported by a pressurized air layer. When a coating material is dispensed from the coating die onto the web to form a liquid coating, the pressure of the air layer is controlled such that the shell translates in space to balance forces from the air layer and the coating bead, while the web is being translated to drive the shell.

  • Publication number: 20210324907
    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.

  • Publication number: 20200189870
    Abstract: Web handling apparatuses and methods are provided to passively control a lateral position of a moving web. The web wraps around support rollers adjacent opposed web edges. One or more guide rollers are positioned adjacent to the support rollers. The guide rollers are in rolling contact with the web edge to guide the moving, misguided web back into its desired lateral position.

  • Patent number: 10384231
    Abstract: A system and method for controlling curl in multi-layer webs. The method can include providing a coated web, curing the coating to form a multi-layer web, and stretching the web during curing of the coating. Some coatings shrink at least partially when cured such that curing the coating induces a strain in the multi-layer web. Stretching the web occurs during curing to induce an opposing strain that at least partially counteracts the strain induced by curing to form a multi-layer web having a desired curvature. The system can include a curing section configured to cure the coating, and can further include a web stretching section, which can be located proximate the curing section and can be substantially coincident with the curing section, such that the web is stretched while the coating is cured.

  • Publication number: 20190112711
    Abstract: A method is provided. The method may include engaging a first edge region on a first surface of a substrate with a first support roller; engaging a second edge region on the first surface of the substrate with a second support roller; transporting the substrate over the first and the second support rollers; repeating the following sequence of steps to form a thin film on the substrate: (a) exposing the substrate to a first precursor; (b) supplying a reactive species to the substrate after exposing the substrate to the first precursor; and depositing a vapor on the thin film to form a coating on the thin film.

  • Patent number: 10221028
    Abstract: An apparatus for steering a web, including a web path having at least one steering roller and an exit roller, each having a mount; wherein the steering roller(s) each have an axis of rotation and wherein the mounts for the steering roller(s) can pivot those axes with a total of two degrees of freedom. An array comprising a plurality of sensors for monitoring the position of the web is present connected to a controller so as to determine the position and angular orientation of the web. The controller adjusts the pivot(s) of the mount(s) so as to control the angular orientation and the lateral position of the web at a particular point along the web path.
