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.

A layered object manufacturing system is described. The system is one arrangement provides for the use of water based adhesives to bind successive layers of paper in generation of a three dimensional model. The paper can be provided in conventional paper sizes and is moveable within the system from a storage stack to a build object location, individual pages at a time. The system typically effects the application of adhesive onto the paper using an adhesive applicator wheel having a plurality of circumferentially spaced apart recesses for receiving adhesive. The wheel is rotatable to convey adhesive filled in one or more recesses to a target substrate and to deposit controlled amounts of adhesive at discrete points thereon.

An applicator, for applying a glutinous substance to a seam between a first part and a second part, comprises a roller, comprising a circumferential surface, and a housing, comprising a delivery port, a scraper, and a shaper. The roller is coupled to the housing and is rotatable relative to the housing about an axis. The circumferential surface of the roller is communicatively coupled with the delivery port. The intersection of the circumferential surface and a virtual plane, passing through the axis, is a non-linear segment. The scraper is geometrically complementary at least with the non-linear segment. The shaper is communicatively coupled with the scraper.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.Attac

[Object] To reduce heat damage to a film when a lithium layer is formed on the film by using a roll-to-roll system.

[Solving Means] A roll-to-roll deposition apparatus includes a vacuum chamber, a film travel mechanism, a lithium source, and a first roller. The vacuum chamber is capable of maintaining a reduced-pressure state. The film travel mechanism is capable of causing a film to travel inside the vacuum chamber. The lithium source is capable of making lithium melt inside the vacuum chamber. The first roller is disposed between a deposition surface of the film and the lithium source. The first roller has a transfer pattern that receives the molten lithium from the lithium source. The first roller transfers a pattern of a lithium layer corresponding to the transfer pattern to the deposition surface while being rotated.

A coating system for applying a coating to a substrate that can be part of a wall assembly. The system includes a positioning stage and an end effector coupled at a distal end of the positioning stage, the end effector configured to apply coating to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the end effector and positioning stage to perform at least one coating task that includes applying coating, via the coating the end effector, to one or more substrate pieces, the generating based at least in part on obtained target surface data; and drives the end effector and positioning stage to perform the at least one coating task.

An apparatus for providing non-contact application of fluids onto web materials and articles is disclosed. The apparatus comprises a gravure roll having a hollow rotating shell having a plurality of cavities disposed within the outer surface thereof and a stationary cylindrical core having a central bore and a channel disposed therein. A fluid disposed within a respective cavity of the plurality of cavities disposed within the outer surface of the hollow rotating shell is removed from the respective cavity by the positive pressure when the positive pressure is fluidly communicated from the central bore through the channel and into the cavity from the surface of the stationary cylindrical core.

A gluing group for a rewinding machine for applying glue to an end edge of a log comprising a delivery roller (12) supported in an idle manner by supporting and translation guiding elements (15, 16), delivery means (20) for delivering a glue line (11) on one of the generatrices of the delivery roller (12), a linear actuator (30) connected to said delivery roller (12) to transmit the approaching and distancing movement of the delivery roller (12) against the paper (11) being wound onto a contrast roller (115).

A rewinding machine comprising such gluing group and a related method for gluing the end edge also form part of the invention.

An applicator (200), for applying a glutinous substance (140) to a seam (330) between a first part (310) and a second part (320), comprises a roller (210), comprising a circumferential surface (216), and a housing (220), comprising a delivery port (222), a scraper (232), and a shaper (234). The roller (210) is coupled to the housing (220) and is rotatable relative to the housing (220) about an axis (202). The circumferential surface (216) of the roller (210) is communicatively coupled with the delivery port (222).

The scraper (232) is geometrically complementary at least with the non-linear segment. The shaper (234) is communicatively coupled with the scraper (232).

A roll coater can be modified by the addition of one or more needle tubes that supply coating fluid to the roll coater in discrete locations across the face of the coating roll. The needle tubes supply a localized band of coating material onto the coating roll superimposed over the uniform coating layer already present on the surface of the coating roll from an upstream coating pond creating a stripe pattern over the uniform coating layer. By varying the relative speeds of the coating rolls in the coater, the width of the stripe can also be adjusted.
