Described here are embodiments of processes and systems for the continuous manufacturing of implantable continuous analyte sensors. In some embodiments, a method is provided for sequentially advancing an elongated conductive body through a plurality of stations, each configured to treat the elongated conductive body. In some of these embodiments, one or more of the stations is configured to coat the elongated conductive body using a meniscus coating process, whereby a solution formed of a polymer and a solvent is prepared, the solution is continuously circulated to provide a meniscus on a top portion of a vessel holding the solution, and the elongated conductive body is advanced through the meniscus. The method may also comprise the step of removing excess coating material from the elongated conductive body by advancing the elongated conductive body through a die orifice. For example, a provided elongated conductive body 510 is advanced through a pre-coating treatment station 520, through a coating station 530, through a thickness control station 540, through a drying or curing station 550, through a thickness measurement station 560, and through a post-coating treatment station 570.

A coating apparatus for continuously forming a coating layer on each surface of a substrate film includes a water tank located on a movement path of the substrate film, a water tank partition vertically located in the water tank, the water tank partition being configured to partition an inner space of the water tank into two zones, including a first water tank portion and a second water tank portion, a roller unit configured to continuously transfer the substrate film, and a heating unit located outside the water tank. The water tank partition is located spaced apart from an inner bottom surface of the water tank by a predetermined distance.

A coating device includes: a fiber passage through which a glass fiber passes downward in a vertical direction; a first flow path which is a flow path allowing a primary resin to flow toward the fiber passage and includes a first branch path horizontally dividing the primary resin moving in a horizontal direction; a first temperature controller which is disposed along the first flow path and controls a temperature of the first flow path; a second flow path which is a flow path allowing a secondary resin to flow toward the fiber passage, includes a second branch path horizontally dividing the secondary resin moving in the horizontal direction, and is located below the first flow path; and a second temperature controller which is disposed along the second flow path and controls a temperature of the second flow path.

A device and method for coating and curing a protective layer on large format graphics comprises a roll-to-roll machine having a coat stage and a cure stage. A roll of printed web material turns about a load reel, passing through the coat stage and cure stage, and is wound around a finish reel. The load and finish reels may be driven by servo-motors. The coat stage comprises a coat pan which is partially filled with coating liquid and a Mayer bar for removing excess coating liquid. The cure stage comprises a light source and a plate. One or more devices, such as idler rollers, dancer rollers, stationary rollers, or load cells, are placed between the load and finish reels to control the path, tension, and speed of the web material.
