A liquid applicator apparatus that allows for fast, convenient, and simultaneous application of a liquid to a plurality of surfaces, including: a handle member; an applicator retaining member; a first liquid applicator; a second liquid applicator; and wherein the first liquid applicator and second liquid applicator are adapted to enable a user to simultaneously apply a liquid to noncontinuous and/or nonplanar surfaces, that are ordinarily difficult to reach, in a fast and convenient manner.

Provided is a coating device for coating a web that is traveling with coating liquid. The coating device includes: a coating bar extending in a web width direction; a partition disposed below an axial center of the coating bar in a vertical direction, the partition extending in the web width direction; and an upstream container and a downstream container disposed on an upstream side and a downstream side in a web conveyance direction, respectively, with the partition interposed between the upstream container and the downstream container, the upstream container and the downstream container including side plates disposed inward in the web width direction with respect to both ends of the partition on a web width direction side, the upstream container and the downstream container being configured to store the coating liquid.

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.

An ultraviolet bottom coating system including a conveyor mechanism configured to route a plurality of cans in a machine direction, wherein the plurality of cans each have a bottom surface and uncured coating material applied on the bottom surface. The system also includes at least one ultraviolet light-emitting diode (UV-LED) device configured to emit ultraviolet radiation towards the plurality of cans, wherein the ultraviolet radiation is configured to cure the uncured coating material onto the bottom surface.

Systems and methods of applying self-seal strips of multiple different adhesives are disclosed. In one embodiment, two spaced apart spoked applicator wheel assemblies are positioned beneath a web of moving shingle stock such that each of the applicator wheels applies dots of different adhesives in an alternating pattern. In other embodiments, a layer of a second adhesive is deposited onto previously applied dots of a first adhesive to form layered adhesive dots with dual properties of both adhesives.
